It is about 12 miles over. Aneroid read 4600 at camp, 7500 on top of ridge, 6900 at Medicine Lake. From the caves we traveled up the gradual pumice slope in a S.W. course & crossed the range at lowest point just north of the highest peak. Then down the west slope into a great pumice basin in which Medicine Lake lies on the west side of the east base of a long, high ridge. Glass Mountain is probably 9000 feet high & has a distinct timberline & considerable snow on the N.E. side. Many of the crests & ridges are pure obsidian of all sorts & kinds & colors. Craterlets are scattered all over the slope, some are rough masses of lava, others are cinder. Medicine Lake is a beautiful, deep blue, clear lake, a/mile long by half a mile wide, surrounded by an extensive forest Pinus murryana, beautiful meadows & little streams make the shores attractive. There are good springs, lots of grass, open parks, snow on the ridge just above. A good place to camp
