Oh that's not anywhere near as bad as what I saw on the west switchbacks up from Guitar Lake a few years ago. Rather dig a hole in the sandy soil there...someone left a standard clear gallon ziplock full of crap in the rocks, which was visible on a moonless night.
A solar latrine would never be put in the NF but if they were along the MMWT...that bag would not be encapsulating that human waste.
