#frost........... very light, summer?
light #frost or frost 'shadows' from frost...going into summer? similarily light #fans or fan-'shadows'
no markable features. looks like a possible boulderfield.
marked as a giant #blotch, but it is more likely multiple features overlapping
1 tiny #blotch, a partial, and either a lot of #frost...or just a false color image
#Interesting terrain......like a frozen ocean
could be a dark fresh #fan......or just shadowing
dark #fans overlapping
small #fans
Something says this is a series of REALLY dusty #fans side-by-side but no way to know. Interestingly unnatural straight egde to the dust

#fans on well formed spiders
#blotches on buggy spiders
#blotches in a #boulderfield
#Penitentes......or #boulderfield.
marked a few #fans, but they're not very clear as either fan OR blotch. Could be it's just surface dust covered over by ice.
one lonely little #fan, and some #boulders
slightly darker #blotch hidden in the dust
there is Soooo much going on in this image it's CRAZY!.........................
............just kidding 😉
narrow #fans in heavily pitted terrain. #boulderfield or #penitentes
dendritic #spider channels
body-less #spiders, heavy #dust but no distinct fans or blotches
#fans and #blotches with #boulders
a few #fan-like marks but they all have a different orientation, so it may be just a trick of light and shadow.Seems like ridges and valleys
#dendritic-spider with a few #blotches
Marked one as a #fan and one as a #blotch, cos the orientation says fan, but mostly they look like blotches. #interesting 'hybrid' features!
#Yardangs with #transparent #hairline-cracks crossing the #ridges all over the image
#blotchfield
tiny #blotches on ice
multi-lobed #fans, a few #blotches on 'scooped-out' terrain and a tiny crater like feature with a shiny spot in it. #boulder? or MPL debris?
#vent with #boulder?
#fans and an #interesting broad channel in what looks to be a lowland area with tributary channels flowing to the main channel
#yardangs forming?? with embroyonic spiders forming too??

#blotches on spiders
#fans from #cracks
scalloped terrain.....#thermokarst-failure?
#interesting terminator of sorts....maybe an elevation change? some #boulders here too
small #fans on ice-sheet
narrow #fans along linear and curving #cracks may suggest an underlyaing shape or feature of the terrain. fan tool froze after marking 75%
looks like #crack-fans and some A1 spiders
looks like #fans and #frost-fans
probably a #fan on lace

#fans on dendritic channels
#ans on dendritic channels
much ice in channels, but no fans or blotches
#blotches in a #slab-ice region
The vent in the lower right is ambiguous. Looks much more like #blotch, but it has expressed a definite #frost-fan
#frost-fan and #fan oon well formed spider
#pits, and #boulders
marked 1 #blotch in upper right, but it really just looks like dust in channels. May be an underlying #boulderfield here
The tinyest #blotches in a transition area. To the right and up, is a #boulderfield, or #Penitentes
faint #blotches ina dusty region
similar size and shape #fans
deep reddish #blotches
a couple of very 'rectangular' shapped #blotches
afew small #blotches and a few larger #fans
1 very small @blotch
#fan, plus a perfectly curved arc of material. Perhaps it is a fan that formed at the moment wind speed was increasing?
2 elliptical #blotches with amazingly well defined and straight edges. Throw in a camera filter glitch for good measure
some small #blotches on #spiders
#Penitentes....or #boulderfield, with a few #blotches from #spiders
marked a few #blotches, but mostly this is just dust in channels
fresher, slighty darker #fan deposited on other fan material....and now I see I missed one!
#blotches along the slope and bottom of a depression
#Penitentes...or #boulderfield
alot of this is just dust in, or spilling from channels, neither blotch nor fan, but I marked a few as #blotches where there were no gaps.
hardly can call these anything, but I'll go with #blotches
Looks more like #fans than anything else
a few tiny 'shadow' #fans and afew tiny #blotches on chain-link spiders
#boulderfield or #Penitentes
small #blotches
nothing but ice....
loooks like a CO2 snow on some of these surface features
the radial nature of the #fans suggest a bowl shaped depression whose center is just a bit south of the bottom left of this image
most of these #fans seem to be laid out in a radial pattern around a 'center' outside the bottom left of the image. A few #blotches also
looks like old #fans with "shadow-fans, and 1 tiny white patch of ice at the bottom of a vent hole
#fans #frostfans and ice tipped #boulders in spiders
wide-spread #frost
#chain-link-spiders
#Penitentes.....or #boulderfield

many pits #boulders and vents. #penitentes
tiny #blotches along the ridge of a depressed region?

a few #fans. looks like a sloping terrain, but maybe just a trick of lighting?
no vents
bad image
a few narrow #fans
Just dust, with little ice
#chain-link-spider, witha few tiny, narrow #fans
A single #fan
#chain-link spider Very processed image. Red "flag" in the upper left and another red mark left center of image. No active vents.
#boulders
may be the most #interesting image I've seen. #Fans, #blotches #frost, channels even spots that look like they're venting 'live' A feast!
#penitentes....or #boulderfield
maybe a #fan but this image is really heavily processed, blurring real definition.
a few #frost tipped #boulders
#blotches on spider channels
#blotches on isolated spider parts ....looks like an underlying #boulderfield
#Interesting image on many levels. Color, elevation, vents with #boulders or shadows..not sure which. Bird shaped #blotch to top it all off!
darker areas may be #blotches but the total shape can't be seen in this image
#pits and #boulders
#blotches and a lot of dusty channels. great image!

terribly over-processed image.No distinguishing features
hard to identify any specific features, lot of dust but no source vent...maybe a few #blotches
Awesome image. Looks like frozen ocean waves. A few small narrow #fans here, and some #blotches too
a lot of dust a couple of #blotches
no blotches or fans, but #interesting #boulder-field or #penitentes?
could be #yardangs forming. #Interesting transparent hairline #cracks throughout the image when magnified
lots of #blue-frost, but hard ot spot any real shapes....some dark dust in channels but no #blotches or #fans
#ice on #boulders.... or #penitentes
another heavy processing job. So bad it blurs the image. This looks like a #boulder-field or #penitentes.
few #blotches on a large well formed #spider
something very odd about this image. Under a little magnification, heavy processing artifacts can be seen, ruining the real image. Too bad!

One small #blotch inside a multi-lobed #frost #fan
One tiny #blotch.......'scooped'-out terrain features
#Yardangs, and a few tiny #blotches. Hairline #cracks also visible overlaying and crossing the parallel ridges
Dang! #Yardangs. with either specular ice or icy #boulders, not sure which
Great pic. I'm calling it a BIG #fan within a little short stubby #fan
#interesting. Tiny spike like dots. Looks like a field of #boulders, but they're probably pits. Also see some fine channeling when magnified
a few small #fans on #chain-spiders
#fanfield.....a few #blotches too #Dendritic terrain
Like frozen waves
no discernable vents. #Interesting terrain
dark #frost-fan and maybe a few blotches ....too dark to tell. Really well formed #spiders too
#interesting color change (not the green stripe) looks like a newly frosted area..or a receding one. few small #fans and many tiny #blotches
#interesting color change (not the green stripe) looks like a newly frosted area...or a receding one.
#fans with very faint #frost on extreme #lace-spider terrain
#fans and #blotches..when magnified. Spider territory.
central #fan has 2 fainter lobes. Was it wind driven at different times? or was it the shape of the vent, with or without wind?
#Interesting #fans.....some have 'wings' at their origination point. Holes but no channels visible. Looks tike a tufted sofa cushion
Mostly just dust seeping through cracks. Markd a few as #blotches
mostly #fans
fading #double-fan
few pin point #blotches and a few #boulders

group of #fans in interesting terrain
#blotches on cracks
#Fans with #frost on #spiders
they look 'directional like fans, but no feathering out, so I'm calling them #blotches
#interesting-feature, these #fans are different colors. Like the dust is of different composition.
#interesting, but can't tell if it's either or!
Looks like a place that used to have features, but is now covered over
#blotches, and a few #fans
Wow. This is the most featureless image I've see to date!
blotches with #frost among #spiders
hunderds of pin point #blotches
maybe a broad #fan
#fans, and a couple tiny #blotches
a few #fan shapes and a lot of dust on spiders
#fanfield with spiders
fading large #blotch at upper center edge
just a few tiny #blotches, but there is an #interesting crater-like feture on the right edge of the image witha channel running through it
this is an amazing image of a mound of #frost/snow in the middle of a large #frost-fan starting in the upper right and runnimg east (left)
remnant shadow of a large #frost-fan
complex mix of #fans and #blotches against a background of spiders
few #blotches in a crazy patchwork of #lace #spiders
3 #blotches on chain spider
a few #fans on dusty chain spiders
#frostfans
monster #fan along right margin
Yes! #Yardangs
alphabet soup...#fans, #frost, #blotches, and #frost.....did I mention #spiders ?
#blotches, a few #fans
#fan and dendritic #spider channels. very homogeneous landscape
#fans, #frost and even a few #blotches
marked it blotch, but now I see a snow #fan from the blotch to lower left. so it should be "fan"
#fanfield but not one directional....not sure that wind is shaping some of these some of this dust looks to have been ejected horizontally
2 large features may be fans, but I marked them blotches
very dusty #blotchfield with a few spiders.
#interesting feature. there is a north/south line, where a transition takes place. elevation change or something. less pitting on left side.
#Yardangs. A lot of speckles, but hard to say what they are boulders or just specular ice 1st ydangs I've seen without those fine ice cracks
few small #blotches
dendritic spiders....pretty featurless otherwise
#boulders in a very dusty area. No discernable fans or blotches
just 2 faded blotches in a field of spiders
a bunch of tiny flotches
looks like just a giant #blotch
something
justa few small #blotches in a dendritic spider field. Interesting circular feature in upper right
complicated #fan pattern variable direction/winds, and the #frost pattern suggests times of no wind. #blotches seem to confirm calm at times
#frostfans that are crossing? like an "X" dead center very well developed #spiders
A few small #blotches and a fan-shaped depression in the upper right. Maybe an fan was there in the past?
a few depressionsand a few thousand #pits
1 large #fan
3 minimal #blotches
#yardangs with a few small #fans and afew tiny #blotches. Crazy hairline #cracks seem to 'float' above the ridges.
#Triple-fan! and #frost
4 tiny #blotches
maybe 1 tiny #blotch...otherwise it's spiders on pig-skin
ugh! this is a messy image to mark. #blotches I guess
dusty #chain-spider
truly bizzare image. #blotches, but not really. #fans, not really. An extremely difficult classification. crazy fine dust #tendrils
#frost-fan, #frost-blotches, interesting image but bad lighting
a half dozen small #blotches and #boulders
#interesting several #double-fans, spider-land
few #blotches
single #fan
tiny #blotches and #pits
#fans along unseen #cracks
the small dark #fan is the only feature I can be sure of
just a few #blotches here along one channel. This area looks like an area where #Pingo's form
no #fans or #blotches, just a very dusty surface
couple of #blotches, mostly just dust
1 small #fan, and maybe a small #blotch.....mostly just dust
lot of #dust, but no distinct features
about 10 #fans, mostly tiny
not enough wind to form fans, so I'm callin them #blotches because the #frost encircles the entire feature
some dust in #channels, a few #blotches from #cracks, and what looks like #shadows of old #fans
just a handfull of tiny #blotches
dusty #channels, but no vents
#boulders but very little dust. just a few #blotches
half dozen #fans
#fanfield, many #frost-fans, and #boulders, one clear #double-fan
#fans along a crack #frost too. marked 2 #interesting-features in upper left quadrant
#fans from spiders
can't differentiate any fans or blotches, but that looks like a decent sized crater in the center
I'm calling #blotches, 'cause I see no fans and mostly it just looks like dust in channels
technically I guess #fans predominate here..low lighting makes it tough to decide on some...and they face all different directions kinda odd
#interesting black 'smudge....not really #fans...also lot of #frost, and a few real #fans
afew small #fans
one #double-fan.....low low lighting
one tiny #fan....looks like forming yardangs
#fans along #crack lines
very weak #fans
I'm thinking more #blotch than fan on this one unless this is a decaying #fan???
tiny #fans.....bad lighting
very faint #fan
#blotches along fine rcacks, looks like these are early yardangs?
#frost and a few #fans
... has some of those very fine channels that look like they're in a layer "on top" of the regular ground surface....as in the #yardang pics
#interesting feature in upper right, but not the 'bright" spot... below and left of that, you have to zoom in, but there is NO mistaking it.
..then many of the dark channels have very regularily spaced circular #pits, each possibly having what looks like a #boulder in the center
..can see a series of very fine cracks crossing the N./S. channels, almost like they're 'above' the surface, in a layer of clear ice (more)
#interesting image....the N to S alignment of the ridge/channels suggests developing yardangs. with 200% zoom or greater, ( to be continued)
#fans and a #blotch or two. look to be lining up along unseen #cracks
could this be an active vent? #sno-cone
#boulders...looks like they're ice-tipped....and a few very fine #channels
on close inspection, this image is a composite of at least 3 frames. some parallel lines suggest possible #yardang formation???
few #fans .....really dimly lit
gives the impression of overlapping #fans...no distinct features
seen in the 'right' orientation, this looks like alligator or snake skin in close-up
an interesting #blotch in the upper left a #fan and some #frost..zoomed in, it appears there may be many more blotches and small fans
much #dust one large #fan and an #interesting feature

Blue 'frost' shows signs of moving downwind (to left), but not fans with a central vent. More like long #fissures that cracked open suddenly
Characteristics of both fans, and blotches, but I'm voting 'fan'. What is not very fan-like, are the sharp borders not usually seen in fans.

marked a few #fans, but they're not very clear as either fan OR blotch.
Could be it's just surface dust covered over by ice.
one lonely little #fan, and some #boulders
slightly darker #blotch hidden in the dust
there is Soooo much going on in this image it's CRAZY!.........................
............just kidding 😉
narrow #fans in heavily pitted terrain. #boulderfield or #penitentes
dendritic #spider channels
body-less #spiders, heavy #dust but no distinct fans or blotches
#fans and #blotches with #boulders
a few #fan-like marks but they all have a different orientation, so it may be just a trick of light and shadow.Seems like ridges and valleys
#dendritic-spider with a few #blotches
Marked one as a #fan and one as a #blotch, cos the orientation says fan, but mostly they look like blotches. #interesting 'hybrid' features!
#Yardangs with #transparent #hairline-cracks crossing the #ridges all over the image
#blotchfield
tiny #blotches on ice
multi-lobed #fans, a few #blotches on 'scooped-out' terrain and a tiny crater like feature with a shiny spot in it. #boulder? or MPL debris?

#fans and an #interesting broad channel in what looks to be a lowland area with tributary channels flowing to the main channel
#yardangs forming?? with embroyonic spiders forming too??

The vent in the lower right is ambiguous. Looks much more like #blotch, but it has expressed a definite #frost-fan
#frost-fan and #fan oon well formed spider
#pits, and #boulders
marked 1 #blotch in upper right, but it really just looks like dust in channels. May be an underlying #boulderfield here
The tinyest #blotches in a transition area. To the right and up, is a #boulderfield, or #Penitentes

deep reddish #blotches
a couple of very 'rectangular' shapped #blotches
afew small #blotches and a few larger #fans
1 very small @blotch
#fan, plus a perfectly curved arc of material. Perhaps it is a fan that formed at the moment wind speed was increasing?
2 elliptical #blotches with amazingly well defined and straight edges. Throw in a camera filter glitch for good measure
some small #blotches on #spiders
#Penitentes....or #boulderfield, with a few #blotches from #spiders
marked a few #blotches, but mostly this is just dust in channels
fresher, slighty darker #fan deposited on other fan material....and now I see I missed one!
#blotches along the slope and bottom of a depression
#Penitentes...or #boulderfield
alot of this is just dust in, or spilling from channels, neither blotch nor fan, but I marked a few as #blotches where there were no gaps.
hardly can call these anything, but I'll go with #blotches
Looks more like #fans than anything else
a few tiny 'shadow' #fans and afew tiny #blotches on chain-link spiders
#boulderfield or #Penitentes
small #blotches
nothing but ice....
loooks like a CO2 snow on some of these surface features
the radial nature of the #fans suggest a bowl shaped depression whose center is just a bit south of the bottom left of this image
most of these #fans seem to be laid out in a radial pattern around a 'center' outside the bottom left of the image. A few #blotches also
looks like old #fans with "shadow-fans, and 1 tiny white patch of ice at the bottom of a vent hole

A single #fan
#chain-link spider Very processed image. Red "flag" in the upper left and another red mark left center of image. No active vents.
#boulders
may be the most #interesting image I've seen. #Fans, #blotches #frost, channels even spots that look like they're venting 'live'
A feast!
#penitentes....or #boulderfield
maybe a #fan but this image is really heavily processed, blurring real definition.
a few #frost tipped #boulders
#blotches on spider channels
#blotches on isolated spider parts ....looks like an underlying #boulderfield
#Interesting image on many levels. Color, elevation, vents with #boulders or shadows..not sure which. Bird shaped #blotch to top it all off!
darker areas may be #blotches but the total shape can't be seen in this image

#fans with very faint #frost on extreme #lace-spider terrain
#fans and #blotches..when magnified. Spider territory.
central #fan has 2 fainter lobes. Was it wind driven at different times? or was it the shape of the vent, with or without wind?
#blotches

they look 'directional like fans, but no feathering out, so I'm calling them #blotches
#interesting-feature, these #fans are different colors. Like the dust is of different composition.
#interesting, but can't tell if it's either or!
#blotchfield
Looks like a place that used to have features, but is now covered over
#blotches, and a few #fans

#fans, #frost and even a few #blotches
marked it blotch, but now I see a snow #fan from the blotch to lower left. so it should be "fan"
#fanfield but not one directional....not sure that wind is shaping some of these some of this dust looks to have been ejected horizontally
2 large features may be fans, but I marked them blotches
very dusty #blotchfield with a few spiders.
#interesting feature. there is a north/south line, where a transition takes place. elevation change or something. less pitting on left side.
#Yardangs. A lot of speckles, but hard to say what they are boulders or just specular ice 1st ydangs I've seen without those fine ice cracks
few small #blotches
dendritic spiders....pretty featurless otherwise
#boulders in a very dusty area. No discernable fans or blotches
just 2 faded blotches in a field of spiders
a bunch of tiny flotches
looks like just a giant #blotch
something
justa few small #blotches in a dendritic spider field. Interesting circular feature in upper right
complicated #fan pattern variable direction/winds, and the #frost pattern suggests times of no wind. #blotches seem to confirm calm at times
#frostfans that are crossing? like an "X" dead center
very well developed #spiders
A few small #blotches and a fan-shaped depression in the upper right. Maybe an fan was there in the past?
a few depressionsand a few thousand #pits
1 large #fan
3 minimal #blotches
#yardangs with a few small #fans and afew tiny #blotches. Crazy hairline #cracks seem to 'float' above the ridges.
#Triple-fan! and #frost
4 tiny #blotches
maybe 1 tiny #blotch...otherwise it's spiders on pig-skin
ugh! this is a messy image to mark. #blotches I guess
dusty #chain-spider
truly bizzare image. #blotches, but not really. #fans, not really. An extremely difficult classification. crazy fine dust #tendrils

the small dark #fan is the only feature I can be sure of
just a few #blotches here along one channel. This area looks like an area where #Pingo's form
no #fans or #blotches, just a very dusty surface
couple of #blotches, mostly just dust
1 small #fan, and maybe a small #blotch.....mostly just dust
lot of #dust, but no distinct features
about 10 #fans, mostly tiny
not enough wind to form fans, so I'm callin them #blotches because the #frost encircles the entire feature
some dust in #channels, a few #blotches from #cracks, and what looks like #shadows of old #fans
just a handfull of tiny #blotches
dusty #channels, but no vents
#boulders but very little dust. just a few #blotches
half dozen #fans

single #fan
#fans along a crack #frost too. marked 2 #interesting-features in upper left quadrant
#fans from spiders
can't differentiate any fans or blotches, but that looks like a decent sized crater in the center
I'm calling #blotches, 'cause I see no fans and mostly it just looks like dust in channels
technically I guess #fans predominate here..low lighting makes it tough to decide on some...and they face all different directions kinda odd
#interesting black 'smudge....not really #fans...also lot of #frost, and a few real #fans
afew small #fans
one #double-fan.....low low lighting
one tiny #fan....looks like forming yardangs
#fans along #crack lines
very weak #fans
I'm thinking more #blotch than fan on this one unless this is a decaying #fan???
tiny #fans.....bad lighting
very faint #fan
#blotches along fine rcacks, looks like these are early yardangs?
#frost and a few #fans
... has some of those very fine channels that look like they're in a layer "on top" of the regular ground surface....as in the #yardang pics
#interesting feature in upper right, but not the 'bright" spot... below and left of that, you have to zoom in, but there is NO mistaking it.
..then many of the dark channels have very regularily spaced circular #pits, each possibly having what looks like a #boulder in the center
..can see a series of very fine cracks crossing the N./S. channels, almost like they're 'above' the surface, in a layer of clear ice (more)
#interesting image....the N to S alignment of the ridge/channels suggests developing yardangs. with 200% zoom or greater, ( to be continued)
#fans and a #blotch or two. look to be lining up along unseen #cracks
#blotchfield
could this be an active vent? #sno-cone
#boulders...looks like they're ice-tipped....and a few very fine #channels
on close inspection, this image is a composite of at least 3 frames. some parallel lines suggest possible #yardang formation???
few #fans .....really dimly lit
gives the impression of overlapping #fans...no distinct features
seen in the 'right' orientation, this looks like alligator or snake skin in close-up
an interesting #blotch in the upper left a #fan and some #frost..zoomed in, it appears there may be many more blotches and small fans

Blue 'frost' shows signs of moving downwind (to left), but not fans with a central vent. More like long #fissures that cracked open suddenly
Characteristics of both fans, and blotches, but I'm voting 'fan'. What is not very fan-like, are the sharp borders not usually seen in fans.
