From the Canyonlands “information” online service:

…I’m not in a very good position to inform or advise you. There is snow in shaded areas here in town, but open areas are presently clear and dry….Overall you’d do best by speaking with the staff in the Island in the Sky, and doing so by phone…

Good luck, of course, getting hold of an actual person on the number they provided.

Elevation in Moab: 4.1k
Elevation at the top of the Shafer Trail: 5.8k
Elevation at bottom of Shafer Trail: 4.5k
Elevation of Murphy’s Hogback: 5.3k

We’ll be fiiinne this Saturday. It’ll give a good excuse to walk up from Mineral, too.

And so it begins….
