Where is Medicine Lake Highlands?
Medicine Lake Volcanic Highlands, in the mountains of northern California, has a natural healing energy that the Native people in the area have long recognized. Corporations sense a different kind of energy—steam—and seek to tap this underground power to run electric generating plants.
What type of volcano is Medicine Lake volcano?
Medicine Lake is a large Pleistocene-to-Holocene, basaltic-to-rhyolitic shield volcano east of the main axis of the Cascade Range.
When was the last time Medicine Lake volcano erupted?
The Medicine Lake Highlands were formed with the development of the broad shield-shaped Medicine Lake volcano around 500,000 years ago. The center block began to collapse along fractured lines between 180,000 and 100,000 years ago, creating an enclosed basin or caldera, 7.5 miles long by 4.3 miles wide.
Is the road to Medicine Lake open?
Area Status: Open The popular Medicine Lake Recreation Area and adjacent Medicine Lake are located in the Medicine Lake Highlands in northeastern California.
Why is Medicine Lake called that?
Aboriginal peoples called the lake Medicine because of its seemingly magical powers, and the United Nations created the Rocky Mountain Parks World Heritage Site partly because of this unique drainage system.
How tall is Medicine Lake volcano?
The most recent eruptions occurred about 11,000 years ago around Mount Konocti. Although Clear Lake volcanic field has not erupted for several millennia, sporadic volcanic-type earthquakes do occur, and the numerous hot springs and volcanic gas seeps at in the area point to its potential to erupt again.
Are there Shield volcanoes in California?
California and Oregon shields. Shield volcanoes occur in California and Oregon in the Cascades and Modoc Plateau provinces. They are considerably smaller than Hawaiian shields, but some are massive: Calilfornia’s Medicine Lake Highland (MLH) has the largest volume of any volcano in the state.
Is Medicine Lake dormant?
Medicine Lake Volcano has been active for 500,000 years. The eruptions were gentle rather than explosive like Mount St. Helens, coating the volcano’s sides with flow after flow of basaltic lava. Medicine Lake is part of the old caldera, a bowl-shaped depression in the mountain.
How often does Medicine Lake erupt?
Although it probably has not erupted for 1000 years, there have been at least 6 eruptions during the past 4,000 years, and it is likely to erupt again in the future. Its proximity to inhabited towns, roads and other infrastructure, it has been designated a “high threat volcano” by the USGS.
What tectonic plate is Medicine Lake on?
Medicine Lake is a broad shield volcano, built up by successive basalt flows. In contrast, the other Cascade volcanoes are tall peaks made mostly of andesite lavas. The magma for all the volcanoes in the Cascade Range originates near the subducting plate, about 120 kilometers below the surface.
When did medicine lake erupt?
Volcanic lakes are formed when a volcano-hydrothermal system, manifested in the liquid phase, intersects with the Earth’s surface. In poetry this would sound like: volcanic lakes are “blue windows” into the “lymphatic system” of volcanoes. Volcanic eruptions are ideal to create depressions (maars, calderas,
