Description - The Warner Ranger District is home to some of the highest points on the Forest. The Warner Mountains and Surprise Valley were caused by a double fault. The mountains rose and the valley dropped. For this reason, the Warner Mountains look most promising to prospectors who come into the area looking for mineral deposits. Clear Lake in the Warner Mountains is a landslide lake formed when a landslide filled part of a deep canyon.
- The north and south Warner range of mountains is one of the most popular areas in the Modoc Forest for vacationers and hunters. There are many excellent fishing streams and small, clear lakes, none of which is heavily used. The South Warner Wilderness is also a great place to do some hiking or horseback riding. The Wilderness is surrounded by many campgrounds that make up the trailheads for the Wilderness area.
Recreation - Folks venturing to South Warner can enjoy excellent fishing opportunities, scenic trail routes, remote camping experiences, and seasonal hunting episodes.
Climate - The variable climate ranges from warm, dry summers to cold, severe, moderately wet winters.
