The cap of the hill is a bed of diabase 30 to 40 feet thick. Specimens No. 694 & 695-both spec 696 was taken from bed of much decon- posd diabase(?) lying below the cap and perhaps separated from it by a bed or beds of quartzite. Upper portions of thermometer hill show gravel + boulder streams or flows (solidfication) in exceptional develop- ment. 50-100 feet below summit on western side there is a well marked flow of this kind which seems to be 150-200 yds long and 20-40 yds wide, descending east southward. The rock illustrated by spec. 696 disin- tegrates into bullet-like gravel scatter- ed through ferruginous yellowish brown sand and this mixture flows down hill like a stream or glacier. The level portion of the hill 850-900 feet above sea is a regular quicksand or quag- mire mixture of clayey matter + quartz bits-
