If you ever have a question about where you need an adventure pass, visit this website.
Wilderness passes are just needed in designated wilderness areas like the San Gorgonio Wilderness.
Thanks for the update!!
The peak was climbed well before the 20th century. The Sierra Club merely mentions that Weldon climbed it in 1938 on their web site, no claim that he was the first.
Went up it with a friend two weekends ago, using his car, and forgot to put the Pass on the dashboard where we were parked at the Green Canyon Creek trailhead on 2N93. We had a citation on the windshield when we got back. That sucks . . .
Sorry to hear. If you send in your Pass number, you don't have to pay it though. Or if you don't have a pass, well, you're probably still fine if you don't pay it :).
