Welcome to Spattercone Trail. This 1.5 mile loop trail will take you to the origin of the recent Hat Creek Lava Flow, an area with many spattercones and associated volcanic features.
CAUTION. Some portions of the trail are steep. Due to hot, dry conditions, it is best to take this hike in the early morning or late afternoon. Carry water!
Stay on maintained trails! Some of the rock outcroppings and cave-ins are unstable and dangerous.
You are standing on the edge of the Hat Creek Lava Flow. About 20,000 - 30,000 years ago, large volumes of fluid lava poured from a series of fissures (cracks in the earth) and flowed northward for 16 miles, covering the floor of the Hat Creek Valley. The spatter cones, further up the trail, mark the approximate locations of these fissures.
