Our programs produce accurate geologic maps and 3-D geologic frameworks that provide critical data for sustaining and improving the quality of life and economic vitality of the Nation. They also organize, maintain, and publish the geospatial baseline of the Nation's topography, natural landscape, built environment and more.

Geologic map and structure sections of the Clear Lake Volcanics, Northern California

The Clear Lake Volcanics are located in the California Coast Ranges about 150 km north of San Francisco. This Quaternary volcanic field has erupted intermittently since 2.1 million years ago. This volcanic field is considered a high-threat volcanic system (Ewert and others, 2005) The adjacent Geysers geothermal field, largest power-producing geothermal field in the world, is powered by the magmati

Geologic map of Newberry Volcano, Deschutes, Klamath, and Lake counties, Oregon

Newberry volcano, one of the largest Quaternary volcanoes in the conterminous United States, is a broad shieldlike landform with a summit caldera 7 km across. It comprises the products of thousands of eruptions, at least 25 of which occurred during the last 10,000 years (Holocene Epoch). Eruptions have occurred as recently as 1,300 years ago, but isotopic ages indicate that the volcano began its g

Geologic map of the Mount Adams volcanic field, Cascade Range of southern Washington

One of the dominating peaks of the Pacific Northwest, Mount Adams, stands astride the Cascade crest, towering 3 km above the surrounding valleys. The icecapped 3742-m (12,276') stratovolcano has for centuries been called Pah-to by the region's indigenous people, who hold the mountain sacred as a symbol of continuity and a source of prosperity and inspiration. Comparable reverence helped secure inc
