Salty, my LEO incident was before 1980, and was a CHP ticket.

SierraNevada, I will indeed to the right thing in the Whitney Zone. But I am still a bit puzzled with the § 261.11 words. a, b, c and e are pretty clear:
a: Don't plug the sewage system and don't throw garbage into a toilet.
b: Don't leave unburied excrement.
c: Keep it out and away from water.
e: hauling and dumping garbage anywhere but in provided containers and authorized dumps.

But (d) is curious:
(d) Failing to dispose of all garbage, including any paper, can, bottle, sewage, waste water or material, or rubbish either by removal from the site or area, or by depositing it into receptacles or at places provided for such purposes.

Everywhere but Whitney Zone, Yosemite and Seki, people have been digging (apparently) authorized cat holes, and burying their poop and TP. Nobody has changed the rules on that.

But where and how did TP become something Yosemite and Seki hikers are required to carry out? For that matter, part d could be interpreted to mean that carrying out poop is also required. Or does a properly dug cat hole fall under "places provided for such purposes"?
