Cahto, August 5, 2018

Our trip to the Bureau of Land Managment’s Cahto holding began with a climb to Cahto Peak for sweeping views along the coast and all over northern Mendocino County. From there we walked to Stoten Opening, a peculiar long narrow grassy meadow.

Lassics, June 23, 2018

The distinctive humps of the Lassics peaks can be seen from some distance around Southern Humboldt. They are good representatives of the confused geology of northwest California, where many types of rock have been jumbled together by tectonic forces. Conical Black Lassic is often mistaken for a volcano, but is actually marine sedimentary rock; Mount Lassic was formed from a different mix of sedimetary rock; Red Lassic has material from a deep ocean trench. We looked at a possible glacial basin from the last ice age, and a recent wildfire.

Red Mountain, June 9, 2018
Red Mountain is a Bureau of Land Management property in northern Mendocino County, and a favorite with ISF for its interesting geology and botany.
This sparse forest has never been logged, though it looks like it. Difficult soils containing toxic minerals limit vegetation. Only a few species can survive.
One of the specialized rare plants that lives on Red Mountain is Red Mountain buckwheat, Eriogonum kelloggii.
