    These are channels carved out by decades of subliming CO2 gas, and the dusty deposts arrising on them show the weak points where pressure releases, and a fountain of gas and dust is fired out.. We have nicknamed them 'spiders'.If there is no wind you get a 'blotch, if wind, ypu get a fan. We are supposed to mark these tp give data on sublimation and wind changes. Plenty more info on the P4 blogs. Great fun. Welcome to P4 ~Pete 😃
