High Quality Content by WIKIPEDIA articles! Mount Tehama (also called Brokeoff Volcano) is an eroded andesitic stratovolcano in the Cascade Volcanic Arc and the Cascade Range in Northern California. Part of the Lassen volcanic center, its highest remaining remnant, Brokeoff Mountain, is itself the second highest peak in Lassen Volcanic National Park and connects to the park`s highest point, Lassen Peak. Located on the border of Tehama County and Shasta County, Tehama`s peak is the highest point in the former. The hikers that summit this mountain each year are treated to "exceptional" views of Lassen Peak, the Central Valley of California, and many of the park`s other features. On clear days, Mount Shasta can also be seen in the distance.
