Is it necessary to mark every black mark? and is the white ice?

I'm really sorry you've got so many, but we would really like you to mark as many as you can. Start from the lager ones and work your way to the smallest untill you can not stand it anymore 😃
If you'd mark the ice with interesting feature tool and #ice - would be perfect.
Thank you so much for doing this!
