SHR Trailheads

Howdy folks,

Just wanted to double-check some details for a North to South SHR hike (Beginning at Twin Lakes).

1. In the Rec.gov system would the starting trailhead at Twin Lakes that goes up Horse Creek to Matterhorn Pass be Robinson Creek?

2. Which trailhead is the official exit where the SHR meets the 120? Appears to be Tioga Pass but not sure that’s the name in the system.

Thanks!
