    Is there a way to collect fingerprints from tree trunks, rocks, etc... in the wilderness?

    Human fingerprinting normally depends on oil left on a smooth nonporous surface.

    Where rough objects like rocks have been handled we're more likely to retrieve DNA than a print image.

    They are now branching into porous surfaces such as paper and kitchen surfaces using chemicals that react with the oils on the skin (I think one is LCV, but that may just be for blood evidence), but yeah, excessively rough objects would be near impossible.
