    The official USGS Topo Vector trail layer preserves a connected Warner Valley approach to Boiling Springs Lake and an around-lake network as twelve atomic NPS trail features. Feature names change along the shared approach, and the lake network contains parallel branches, so the features are retained rather than collapsed into a single inferred line. Dataset publication warns that temporal changes may have occurred and current NPS conditions remain necessary.

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.
