Marshall is a typical unmaintained trail along a brook. Tons of roots, goes in, out, and next to herb brook on both sides (look for cairns) with a fully wooded summit and summit sign. A boring hike that unless going for all 46 high peaks I wouldn’t recommend it. I paired it with Mt Colden, starting/ending at the ADK loj. This mountain took me 1:15 up and about the same coming down.
