>>490218 also if you reduce the point of the stilt /modified shoe to a nail or so it should be hard to see it from further away.
this might have a advantage vs animal tracks since those might be followed by a hungry trapper. so use bird track since they are more likely to be ignored.
besides that the ash will be gone soon since wind will collect it and move it to certain areas. (like snow drifts)
rain will wash it then it will harden to some extent. the evaporation cycle of the seas and clouds should unaffected or you are kill
>>489909another idea would be to fake a undisturbed area. for example to mix the ash with some binder to make "ash rocks" and lay a secret path. (think of sandstone among of sand or snow-ice among snow ) On your way you will step on the stones that blend in surroundings. but wont leave footprints.
