Excellent Kathy! I've passed by this peak many times while driving on 395 and have wondered what the climb would be like. This is on my short list of peaks to climb.
Hmmm, I must have driven right by this peak on my way to do Boundary and wasn't aware of what I was looking at. I will be next time I go that direction. A great page.
Glass Mtn is not actually the highpoint of Glass Mtn Ridge as stated. The highpoint is located a short distance to the south, probably only important if you are chasing the DPS point.
I think I missed the topo map you provided entirely, having only read the text at the very top. So I'm a moron. It was abundantly clear to folks who can read. :-)
