Pine Mountain is a rhyolitic mountain east of Bend and south of U.S. Route 20 (US 20) in eastern Deschutes County, Oregon, United States. [3] It is the site of an astronomical observatory called the Pine Mountain Observatory. [4] The mountain is a part of the Deschutes Formation (which is related to Cascade volcanism) and is the southeasternmost exposure of the formation and is of similar age to Cline Buttes. [2] Pine Mountain is also well known for its spectacular "glass off" weather conditions which are ideal for paragliding. [4]
Pine Mountain shows considerable erosion and is covered with thick soil deposits. [3] The mountain consists of basalt, rhyolite, andesite and dacite. [5] [6] Dunes mark the northwest flank of the mountain, consisting of pumiceous dust and lapilli. [7]
On September 17, 1984 a large fireball was seen from the Pine Mountain Observatory heading northeasterly before breaking into six orange fragments. [8]
