Salty,
It's not that easy. Those who patrol Cucamonga Wilderness can tell you.
You need people...a lot of people. There is not a volunteer base big enough in the Owens Valley to get compliance rates where they need to be...in the very high 90s and you also have interagency problems in play here. Mt Whitney has its high compliance rate not because of there is a permit required for day hiking but because there are boots on the group checking those permits...both volunteer and seasonal rangers.
Mt. Langley will never require a zone stamp, it is just not that popular. People do not plan for the better part of year to get to 14,023' like they do for Mt. Whitney. I know I did not...or for any other Sierra peak.
