Black Rock Desert volcanic field, Volcanic field in west-central Utah, US
Black Rock Desert volcanic field is a volcanic zone in central Utah featuring cinder cones and lava flows spread across a broad landscape. The area displays multiple types of volcanic formations that developed over millions of years as molten rock reached the surface.
The oldest volcanic eruptions occurred more than 6 million years ago, creating rhyolite lava domes and basalt flows in the northern section. A younger eruptive phase later added more features to the volcanic landscape.
Petroglyphs scattered across the area mark where ancient peoples once traveled near prehistoric lakeshores. These rock carvings remain visible today and show how people lived in and moved through this volcanic terrain.
The area can be reached via dirt roads from nearby towns, and visitors should gather information at local ranger stations before heading out. Preparation for desert conditions and navigation tools are helpful when exploring this remote landscape.
One of Utah's most recent volcanic episodes happened in this area during the medieval period, leaving fresh-looking cinder cones and dark basalt flows across the ground. These comparatively young features stand out from much older volcanic formations nearby.
