The Sand Mountain Volcanic Field (also known as the Sand Mountain Field) is a volcanic field in the upper McKenzie River watershed, located in the United States in Oregon. Part of the Cascade Volcanic Arc, it lies southwest of Mount Jefferson and northwest of Belknap Crater and Mount Washington. Its highest elevation is 5,463 feet (1,665 m).

Sand Mountain is a singing sand dune 20 miles (32 km) east of Fallon, Nevada along U.S. Route 50. The dune is two miles long and 600 feet (180 m) high. [2] The full sand field area is 3.25 square miles. [3] The sand originates from the ancient Lake Lahontan, that for the most part dried up 9,000 years ago.
Sand Mountain, especially the northern end, i.e. eastern Jackson County and northern DeKalb County, is mostly a rural, [15] agricultural area, with a mix of chicken, cow, and potato farms, as well as other assorted farms, [16] and large expanses of both rolling pastures and forests. [1]
Black sand is sand that is black in color. One type of black sand is a heavy, glossy, partly magnetic mixture of usually fine sands containing minerals such as magnetite, found as part of a placer deposit. Another type of black sand, found on beaches near a volcano, consists of tiny fragments of basalt.
The researchers calculated that the sand volcanoes formed 2,500 years ago. About 50 miles (85 kilometers) away from the sand volcanoes, the scientists also found a large river channel that filled ...
There are clear trends among volcanic centers in the area including at Sand Mountain and Inaccessible Cone, suggesting underlying faults; according to Taylor (1965), Belknap's alignment with the Spatter Cone Chain and Blue Lake Crater might similarly indicate underlying faults or fractures connecting the vents at depth, though there are some ...
Close to Santiam Pass, [2] it forms part of the United States Geological Survey topographic map for the Three Fingered Jack volcano. [1] Hayrick Butte lies south of Three Fingered Jack near Hoodoo Butte, Sand Mountain Field, Potato Butte, and Black Butte, with Belknap Crater and Mount Washington further to the south. [3]
