A moderately difficult out and back trail to the seldom visited Monument Geyser Basin.
This trail meanders along a gentle gradient following the Gibbon River then it turns sharply uphill and climbs 500 feet in 1/2 mile to the top of the mountain! Footing is on eroding geyserite and rhyolite, somewhat reminiscent of ball bearings. The geyser basin is a very interesting collection of dormant cones of varying sizes. One resembles a thermos bottle! Most of the activity here has dried up; hikers looking for exciting thermal activity will be disappointed, but those looking for adventure will find it. Remind folks to stay on trail!
