    The NPS brochure map depicts the Warner Valley trail network, including the Pacific Crest Trail, Drakesbad, Devils Kitchen, Dream Lake, Boiling Springs Lake, Terminal Geyser, and the connecting trail junction pattern. The map does not print atomic mileage for these connectors.

    Terminal Geyser Trail starts at Warner Valley Trailhead and is 5.8 miles round trip. It follows the PCT to a y-junction serving Dream Lake, Devils Kitchen, and a horse trail, then veers left toward Boiling Springs Lake. A second y-junction is at 0.9 mile, followed by a signed three-way junction southeast of Boiling Springs Lake. At 2.5 miles the route rejoins the PCT; about 25 feet later another junction sends the PCT toward Little Willow Lake while the Terminal Geyser route continues ahead.

Before you go

These open questions need confirmation; Wayproof does not fill them with guesses.

What exact segment traversal connects each remaining published Lassen trailhead and destination, including shared junctions and alternatives?

Wayproof publishes complete, bidirectional, distance-bearing trailhead-to-summit approaches for Lassen Peak and Brokeoff Mountain, plus a bounded summit approach for Cinder Cone; a connected distance-bearing parking-to-basin-entry graph for Bumpass Hell; and the atomic shared approach plus around-lake network for Boiling Springs Lake. Cinder Cone rim/crater circulation and the full Bumpass basin circulation remain explicit route-specific gaps. It also publishes ordered, bidirectional Warner Valley topology for Devils Kitchen and Terminal Geyser, but atomic leg distances remain unknown where route descriptions print only cumulative positions. These remaining questions still require route-specific reconciliation.

Open question. Linked evidence does not resolve this gap.
