So it's been since 2008 since my last Whitney summit. Completed one day summit via Mountaineers, then did Thor the next day with larger group. Since I haven't been back in 12 years, I've been reading through the post. Doesn't seem like too much has changed, still need permits, don't need bear canister via Mountaineers. My uncle whom I hiked with passed so I don't have all his knowledge anymore. I've got permits for May, group of 6. The current plan is to do Thor via smiley face rout- Iceburg lake first day. Russel and Whitney second day and maybe hike out or hike out 3rd day. I plan on trying to keep my pack below 30lbs. I currently live in Idaho so I'm not worried about elevation or temperature( I'm used to a high of 30F and lows down to single digits) and I have tons of snow experience although I did notice the snow pack this year for Whitney is lower than normal. I'm trying to look at old pictures and get my gear in line. The main thing that I will be using now that I didn't when I was younger is some trekking poles. Any advice or suggestions that might help would be great.
