The goats are attracted to salt - and are getting way to comfortable around people. Almost all of these were chased off, one of the ones in Glacier was using the trial, we climbed up a bit to let him pass. All the goats I have encountered seem to respond to rocks.
There was a fatality in Olympic NP a few years ago.
I have never had a problem with them messing with a campsite, but if you left sweaty clothes hanging you might.
Good to know. I keep a clean camp, but when destructive animals are around (javelinas come to mind), I usually go ahead and pack up even if I'm returning for the night. Sounds like the goats are no more bother than any other critters.
Salt draws in the Colorado marmots like crazy. I spent a night at the Boulderfield site on Longs Peak, and those bold buggers would sit a few feet from the tent, waiting to pounce on anything left unattended for a moment. I've heard of trekking pole grips & pack straps being chewed up, and I'll bet they'd love to drag off a shoe or boot. That'd make for a rough hike home!
