Before you go

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

Does the selected Half Dome date, route, and cable status require and satisfy a Half Dome day-use permit?

This route profile identifies the permit topic without adding an incomplete rule; a focused permit batch must model current seasonal applicability, lottery mechanics, and fulfillment coverage.

Open question. Linked evidence does not resolve this gap.

No specific claim evidence is linked to this question.

Which reviewed NPS trail features form each Yosemite Valley route, variant, junction, and turnaround from its exact access point?

The official sources establish named routes, starts, objectives, variants, and published distances, but continuous feature-by-feature topology still requires a separate reviewed geometry pass; proximity is not a connection.

Open question. Linked evidence does not resolve this gap.
