Cinnamon Butte, Thirsty Point, and Kelsay Point are forested cinder cones along a WNW-ESE line immediately west of the Cascade crest and NE of Diamond Lake. The cones have well-preserved summit craters, and lava flows appear to be unglaciated, suggesting they are younger than 11,000 years (Sherrod, 1991). Lava flows from Cinnamon Butte pass through gaps of late-Pleistocene moraines, although all three cones are covered by the roughly 6,845-year-old Mazama Ash associated with the formation of Crater Lake caldera (~30 km S). Other Pleistocene cinder cones and a lava dome are located nearby, mostly west of the Cascade Range crest.
