3.4 miles, 2000’ elevation gain, 5:10 roundtrip time
Brian and I left US 50 near Maysville and drove north on CR 224 and then turned left on FR 228 and climbed steeply up into the national forest. We left Brian’s vehicle when the road got too rough and 4-wheeled in my truck up to about 11,200’ feet. Remarkably, we gained nearly 3000 feet of elevation on the road in a few short miles after leaving the highway. We proceeded to walk up the road a short distance and then bushwhacked to the right up a steep slope to gain the south ridge of Missouri Hill.
we left the road here and angled up the slope to the right to the ridge. missouri hill can be seen ahead.
We followed the ridge to treeline and then engaged a talus slope all the way up to the summit.

lost mountain, our next objective
After a while we picked our way down another talus slope to the saddle between Missouri and Lost Mountain.

Missouri seemed like a big pile of talus rubble.

The climb up to the summit of Lost Mountain was much friendlier, mostly on grass.
We enjoyed the nice views here as well.

After half an hour or so we headed down the slope to the southwest and contoured below Missouri back to the south ridge and then on down to the road.
the talus insisted that we fully pay our dues
The climb covered only about three and a half miles but it seemed like more than that.
