Overview

Jacks Backbone is a volcanic peak in the Cascade Range. It is located in Lassen National Forest, just west of Thousand Lakes Wilderness and north of Latour State Forest. The rocky summit offers great views of Crater Peak, Lassen Peak, and the Bunchgrass Valley.

Cross-country travel is required to access the summit, although a number of forest roads surround the mountain and offer a variety of scrambling route options. This area has a lot of brush, so it's worth your time to scout out a good line and also to wear some sturdy pants. The peak has approximately 800 feet of prominence.

The Name

According to California Place Names (Gudde & Bright), the mountain was named when J.M. Simmons' hired man, Jack, was washing his clothes in a nearby stream (probably Cow Creek). Simmons noted "when you're humped over like that, you look like yonder mountain".

Backbone Lake Trail

There is also a hiking trail located on the northeast side of the mountain. Forest Service Trail 3E02 follows an old road alignment northwest for 3/4 mile, climbing 370 feet in elevation and ending at Backbone Lake. This clean, shallow pond is very scenic with a great view of the west side of Crater Peak. There is no sign or trailhead, so bring a map and look for the clearing where the trail starts.

Getting There

Jacks Backbone is accessed by Forest Service Road 16, which begins at State Highway 44/89 at the Ashpan Snowmobile Park. Follow this road northwest for approximately 10 miles to access the east side of the mountain and the Backbone Lake Trail.
While winter and spring automobile access is usually limited due to snow, the convenient snowmobile park makes a snowmobile approach to the area a feasible option.
Alternate access to the southwest side of the peak is available through Latour State Forest. Forest Road 32N47A, located on State land, probably provides the highest starting point for a scramble of the peak. This road begins near Cow Creek and ends at an old log landing near the National Forest boundary.
