Hi Guys/Girls,
I just climbed Green Butte Ridge (including the top of Sargents Ridge) last weekend so I have some beta for you.
The Fifth season did not have permits. They informed me they would not have permits until April so they may have them on the 1st or maybe not. Either way you can get a permit for $25 at the trailhead - self registration. The trailhead permits are not the annual pass they are only good for 3 days.
There is tons of snow! However I dressed for a winter climb and it felt like July! So pay attention to the weather. For my climb it was around 60 degrees low on the mountain with no wind and only light clouds so it was Hot during the day. I slept at 10,000' and it was roughly 25 degrees at night. Also the sun was brutal, bring lots of sunscreen if your not going to be totally covered.
We climbed the ridge proper and did harness up and used a rope, pickets and slings/cordellete (to sling rocks).
Also we started the approach at 10am saturday and the snow was already starting to get soft. We wore/carried snow shoes and poles and even with the additional weight I was glad I did. Also there was a huge avalanche in Avy Gulch around valentines day, which on the mountain is invisible due to later snow fall. However when we descended the mountain via Avy Gulch we found varying soft and hard snow which became very soft to hard snow by late in the day. For this reason I was also happy to have snow shoes for the walk out. Up to you though.
Hope this helps, good luck to you all!
