Monitor ridge

From Marble Mountain Sno-Park follow trail 244 through the forest and on to the ridge. 216B via June Lake is also possible, but has longer flats. Stay on the ridge going directly N from the forested cliff (W of the smaller hill). The ridge finally merges with the Monitor ridge and the summer route at about 2300m (7600ft). With only a short hike to the crater ridge and summit. Other routes are likely to be possible depending on snow cover and conditions. Many nice and scenic camp sites below forest line or just above.
