Mammoth area, hot creek camping/hiking

Registration is now open on my geology.trampleasure.net website.

• You need to register on that site to be officially included.
• When you register, you will not pay online, but I'll send you information about how to pay (PayPay, Venmo, CashApp, Zelle, or good old check in the mail).
• If you can't make all five days, you can still register if you can make at least three days of hiking.
• The road to Devil's Postpile is closed for construction until July, so we won't he able to visit this this year.

Just a placeholder to let folks know this is happening. You can RSVP to this event if you think you will come, but we'll create another event in late April for confirmation of your attendance.
We have Obsidian Flat Group Campground reserved for June 15-21. This is a 'primitive' campground that only has vault toilets (no running water), but is located right below an obsidian dome, and not near any other campsites, so we'll be on our own.
If anyone wishes to stay in a hotel, there are options in the Mammoth area, or elsewhere along highway 395. I recommend getting a reservation early, as they may book up (especially the more budget-friendly ones). The campground is closest to Crestview, but is also close to Mammoth. Folks who stay in the hotel are welcome to join us at the campground for socializing, campfire, etc.
More details about the trip, including maps, photos, and geology information, can be found here.

Update on getting there through Tioga pass (Highway 120).
This is considered the best and fastest way to get to our destination from the SF Bay Area, but Peak Hour Ticketed Entry tickets are required (even if you have a Senior or other National Parks pass).
I just bought one last night (5/6) and as of that time there are still 231 left. The only timeframe that was available was 6:00 AM to 2:00 PM, which should work well for getting through. This means you can enter during those times. The pass is good for three days, so you'll need to buy one for the drive out and one for the drive back. They are only $2; I think it's just about limiting the number of people going into the park. I'd buy one now if you think there's a chance you are going to need it.
