from "Rock Climbing Utah's Wasatch Range" guide book -
"Approach: Drive up BCC4.2 miles to the first swhitchback of the S-Curve. The road branching off to the right leads to a parking lot and the trailhead to Lake Blanche. A three-mile hike following a good trail is required to reach the lake, and a half-hour scramble reaches the base of Sundial, the prominent summit south of the lake.
Descent: The descent can be accomplished by continuing south on the Sundial ridge (toward the true summit) until downclimbing to the east looks feasible. Another option is descending a gully just north of the final ridge to the summit and dropping west.
