Prospect Peak, also known as “East Prospect”, is one of the major peaks in Lassen Volcanic National Park (LVNP). At 8338 feet, Prospect Peak offers great views of the NE portion of LVNP as well as beyond into Lassen National Forest. When viewed from Hwy 44 to the north, twins Prospect and West Prospect Peaks tower above the surrounding terrain. There is an impressive lava flow between the mountains that especially stands out in the winter. Prospect Peak has 1938 feet of prominence.
Compared to the popular nearby Cinder Cone Trail, which shares the approach from the Butte Lake Trailhead, the Prospect Peak Trail offers a longer, shadier, and quieter experience – and expansive summit views that include Cinder Cone with a Painted Dunes and Fantastic Lava Flows backdrop.
You can also see Mt Shasta, Lassen Peak, Mt McLoughlin, Caribou Wilderness, and several LVNP lakes.
Prospect Peak is one of four shield volcanoes located in LVNP; each is topped by a cinder cone.
A Forest Service fire lookout was built atop Prospect Peak around 1912, prior to the 1916 establishment of the National Park. The building served as an active lookout until 1935, when the Civilian Conservation Corps built a new lookout on neighboring West Prospect Peak, 2 miles away on National Forest System lands. The wooden Prospect Peak lookout was added to the National Register of Historic Places in 1978. The lookout continued to stand atop the peak until at least 1980 (last dated photo I could find). All that remains now is a pile of weathered lumber. This may just be the remains of an outbuilding, as I came across one reference that implies the lookout building was actually dismantled, removed, and rebuilt in a storage facility in southern California.
Take California Highway 44 to the Butte Lake Road. This is approximately 11 miles east of the junction with Hwy 89 in Old Station, and 40 miles west of Susanville. Head south on the gravel Butte Lake Road for approximately 6 miles to Butte Lake. Park in the small lot near the boat launch, looking for the signs for Cinder Cone.
In LVNP, only Lassen Peak and Brokeoff Mountain have higher summits attainable by trail.
The trail to the top is 3.75 miles one-way from Butte Lake, and gains 2250’ of elevation. Follow the signs and trail heading for Cinder Cone. During this first stretch you are actually on the old alignment of the Nobles Emigrant Trail. In about 0.45 miles, there is a signed trail junction on your right. Take this the remaining 3.3 miles to the summit. A short loop around the outside rim of the forested summit crater will provide you with excellent views in all directions.
If you still have energy when you get back to the trail junction, I recommend turning right and making the short jaunt to Cinder Cone. Then enjoy a refreshing dip in the cool waters of Butte Lake before your drive home.
A geologist once found a 6-inch diameter pumice rock atop Prospect Peak. It was believed to be from the May 1915 “Great Hot Blast” of Lassen Peak, meaning it would have traveled 10 miles!
