    A bounded National Digital Trails query returned connected USFS-originated, distance-bearing features for Parker Lake and Heart Lake, plus an approximately two-mile named Convict Lake Loop shore-trail component whose endpoints do not close. Fourteen selected public-domain features are retained in a versioned snapshot.

Before you go

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

What are the official distances and exact facility inventories for the Crystal, Heart, and McLeod Lake day hikes?

The official map establishes route identity and access, but this batch does not infer distances or facilities from map scale or symbols that are not unambiguous.

Open question. Linked evidence does not resolve this gap.

No specific claim evidence is linked to this question.

Which candidate trailheads, roads, restrooms, and seasonal services will be open for the planned trip?

Access and developed facilities are seasonal and condition-dependent; recheck current Forest Service alerts and local trailhead status shortly before departure.

Open question. Linked evidence does not resolve this gap.
