Diamond Craters VulkanDiamond Craters is a 60 sq km volcanic field in SE Oregon, 11 km east of highway 205 and 64 km (40 miles) southeast of the town of Burns. It consists of cinder cones, maars (explosion craters) and lava flows.
Diamond Craters were named after the Diamond Ranch, established in the area by the pioneer Mace McCoy and his partner Albert Hugh Robie. The ranch used a diamond-shaped brand, hence the name.
Beschreibung:Tectonic uplift at Diamond Craters has created a series of six overlapping topographic highs, the highest is known as Graben Dome; its 1435-m-high summit is cut by a NW-SE-trending graben 0.4 x 2.1 km long and 30 m deep. Lava flows on the eastern side of the volcanic field and scattered cinder cones and maars formed during the last stage of activity.
