Actually winter is a fine time to climb Drury. The tram runs year round, and skiing or snowshoeing to Drury is not much more effort than going to San Jacinto.
Plz insert topo for these coordinates 33.8082N -116.6857W.
Topo link added!
the route you linked from Humber Park is my route for Tahquitz Peak. The route you want is "via Humber Park (devil's slide)".
Thanks Alex. Fixed it
Your coordinates show that this peak is on the east side of Jean Peak while the peak is actually located on the west side of Jean. Please try these numbers instead. I think you will find that they are quite exact.
