The high ridges of the Warner Mountains dominate this 2021 survey, marking the border between Modoc and Lassen Counties within the Modoc National Forest. This remote section of Northeastern California is defined by its seasonal hydrology and high-elevation landforms, including Emerson Peak and Bearcamp Mtn. The landscape is characterized by narrow valleys and drainages such as Long Valley and Snowslide Canyon, which feed into complex stream systems like East Creek and Mosquito Creek.
