National Forest - California
The Modoc National Forest protects parts of Modoc (82.9% of acreage), Lassen (9.4%), and Siskiyou (7.7%) counties. Most of the forest was covered by immense lava flows occurring over the last 500,000 years. The eastern part of the forest east of Alturas contains the Warner Mountains. The Warner Mountains drop steeply on the eastern slopes, whereas the western flank has a more gentle topography.
