Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Eagle Lake Field. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Eagle Lake Field page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

Deformation History

There is no Deformation History data available for Eagle Lake Field.

Emission History

There is no Emissions History data available for Eagle Lake Field.

Forest-covered Brockman Flat, formed by lava flows from a chain of cinder cones in the Eagle Lake volcanic field, extends into Eagle Lake. The cinder cones, out of view to the right, were formed along N-S-trending faults within the Eagle Lake volcano-tectonic depression, whose SE margin forms the peaks beyond Eagle Lake. The flows from the depression represent the southernmost late-Quaternary magmatism associated with backarc spreading in the NW Great Basin.

Forested cinder cones of the Eagle Lake volcanic field rise above the SW shore of Eagle Lake. The volcanic field occupies the junction of the Cascades, Sierra Nevada, and Basin and Range geologic provinces. The Eagle Lake field consists of 15 cinder cones and basaltic lava flow vents within a larger Quaternary basaltic field. The vents are aligned along faults defining the Eagle Lake volcano-tectonic depression. The latest eruptive period occurred during the late-Pleistocene or early Holocene.
