Located east of Mono lake, the great western divide, this part known also as the Mono Divide. Tioga Pass via Lee Vining canyon, as you likely know, and the east road into Yosemite. Mt. Dana, Gibbs, Tioga etc. straddle that backdrop, truly amazing country any time of year.
It (Tioga) was closed in early October, then reopened lacking snow but closed for season late January.
