A steep, slightly technical descent beneath the trees, down a little-used corner of the canyon.”
— David Gregg
From the top of Marshall, look for a trail marker, a street-sign looking pole with a white sign, and turn right. This trail is short, but steep and fun and, like the rest of Marshall, is also buried under the trees. The little-used trail quickly snakes its way through the forest, losing altitude in a much more direct line than the fire road on the way up.
I rated it intermediate/advanced because some of the steep, thin sections have a rut, and some of the sections are sort of "tight", or confining. Eventually, the trail drops you into a shaded clearing with a picnic bench at its center with trails branching in all directions.
