About Eagle Lake Field
Eagle Lake Field is a fissure vent(s) rising to 1,652 meters (5,420 feet) in United States's North America Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Eagle Lake Field is located in United States, within the Basin and Range Volcanic Province of the broader North America Volcanic Regions. Situated at 40.63° N, 120.83° W in the Northern Hemisphere, the volcano lies within a temperate climate zone. With a summit elevation of 1,652 meters above sea level, Eagle Lake Field is a moderately sized peak that remains accessible to hikers and researchers for much of the year. The volcanic landform is characterized as a cluster, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
GVP Reference Summary
The Eagle Lake volcanic field occupies the junction of the Cascades, Sierra Nevada, and Basin and Range geologic provinces, and 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, and are the southernmost example of late Quaternary back-arc spreading in the NW Great Basin. The Brockman Flat lava flow, the largest of the younger flows, was erupted from a N-S oriented 3-km-long fissure vent along a fault that forms the west boundary of the Eagle Lake basin and created an approximately 63 km2 tube-fed flow field that extended across the Eagle Lake basin to the east side of Eagle Lake. Miller (1989) mapped four Holocene centers west of Eagle Lake; however, recent 40Ar/39Ar dating indicates that the youngest lava flows were erupted during a relatively short interval between about 130 and 125 ka that was unlikely to span more than a few thousand years (Clynne et al., 2017).
