San Gabriel Mts.
Mt San Antonio
From Manker Flats to ski hut. Climbed steep and deep snow fields to Devils Backbone ridge just below summit at 10,064ft. Tricky descent down the Devils Backbone due to boiler plate icing conditions and some steep drops down NE gullies. Eventually elected to take deep snow slopes down Manker Canyon back to start rather than further risk a quick exit down the wrong slope. Local maps do not illustrate the nature of this ridge but then I guess the name is the big clue.
