Hobart Butte is a mountain in the United States. Hobart Butte is located in Lane County in the state of Oregon, in the western part of the country. It is 3,800 km west of the capital city Washington, D.C. The elevation of Hobart Butte is 755 meters above sea level, or 135 meters above the surrounding terrain. Its foothills are about 1.3 kilometers wide.
The land around Hobart Butte is mostly hilly. Bald Butte is the highest place in the area, 1,216 meters above sea level, 10.7 km southeast of Hobart Butte. The nearest larger town is Drain, 17.8 km west of Hobart Butte. Hobart Butte is almost covered in pine forest.
The climate is Mediterranean. The average temperature is 9 Β°C. The warmest month is August, at 19 Β°C, and the coldest is December, at 2 Β°C. The average rainfall is 1,427 millimeters per year. The wettest month is November, with 229 millimeters of rain, and the driest is July, with 11 millimeters.
Cinnabar is occasionally reported as occurring in the high-alumina clay deposit on and near Hobart Butte.
From the principal quarry, lying near the crest of the Butte, about 3 miles (ca. 5 km) northwest of the Black Butte mine, 12,000 to 15,000 tons of clay were shipped to a brick plant at Willamina during the 1930s (Oregon Department of Geology and Mineral Industries 1951, p. 90-91).
A substantial tonnage of the clay was blocked out by a joint drilling program of the U.S. Bureau of Mines and U.S. Geological Survey in 1943 (Allen, Loofbourow, and Nichols, 1951).
Quicksilver was not reported in any of their analyses. It is thought that perhaps realgar, the arsenic sulfide which is rarely found in the clay, has, on occasion, been mistakenly identified as cinnabar. On the other hand, cinnabar may reasonably be expected to occur here, since the Butte lies within a district of rather widespread hydrothermal alteration and cinnabar mineralization.
The rocks from which the clay has derived are thought to have been volcanic breccias, tuffs, conglomerates, lava flows, and mud flows of the Fisher Formation (Brookes, 1963).
