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.
