From Betty Bear Hut ski for 1/8 mile through timber E to Lily Pad Lake. Ski SE then E around the lake to intersect a snow-covered road which leads through timber and an open area E to an open saddle at 11,400 feet.
Ski E from the saddle on a snow-covered road which traverses SE then E around the head of the Ivanhoe drainage about 1 mile to the Hagerman Tunnel portal (11,520 feet). The road ends at the portal. Take a climbing traverse NE from the portal for 3/8 mile to intersect the Hagerman Pass Road at 11,800 feet. The Hagerman Pass Road can be obscured by snow, but is sometimes marked by bamboo poles. This route also may be marked with blue diamonds, but they are infrequent. Climb the Hagerman Pass Road for 3/8 mile NE to Hagerman Pass (11,925 feet). Then follow the Hagerman Pass road down to the Skinner Hut.
Much of this route is at or above timberline. Be ready for limited visibility due to storm and wind.
