Route: South Ridge from CDT via Boss Lake
Posted On: 2019-10-16, By: supranihilest
Info: The route up Monumental from Boss Lake, by taking the CDT to the ridge and traversing over several 12ers, is incredibly long. The road from Monarch to the start of the Boss Lake trail is obvious, and the trail to Boss Lake itself is obvious, though steep. From there follow the CDT; at one point there's a marker that says the trail is closed. I don't know why as I headed off on a route that I got from Google Maps that doesn't seem to exist, so my advice: STAY ON THE CDT! It will eventually lead you to a saddle just north of 12er Bald Mountain, and from there the route goes north over several 12ers and finally to Monumental. Most of this off-trail portion is tundra though there's plenty of talus thrown in, especially Monumental's summit push. The entire route is dry.
