The REI in Fresno sells Probars (Blackstone and Nees, Riverpark – east side of Blackstone). You can also get them at Whole Foods (Shaw and Palm).
People poo poo the marmot stories… I just observe things and act accordingly. Go ahead and call the rangers – they observe a lot more than I do, as they live there all season… there is a short list of tow services that will come out from Three Rivers on the ranger station outside, and a pay phone. I bring a tarp until September.
There are other places in the Sierra where marmots chew up cars. The campground host at Courtright Reservoir – arguably far less bombarded with tourists than any park – told me he has problems with them attacking his truck. But, consider that it's parked there for weeks at a time…. They also have problem bears as well.
Marmots in Yosemite totally wrecked the handles of my trekking poles, leading to my obtaining a Lightheart Solo, which allows me to keep the poles inside with me, rather than the outside ala the Tarptent Sublite. And, it led to the habit of washing the handles off frequently in streams, in hopes of decreasing the salt content.
Marmots harassed us to the point that we threw rocks at them up in the Tablelands (Sequoia NP). Those things are not afraid of anyone. One of them stood up like a little bear and stared at me from five feet away as I was trying to set up the tent. They would have made off with stuff sacks if we hadn't been vigilant. One of us had to be on duty to chase them while the others were setting up and stashing gear. I was glad to have the bear cans.
Deer and squirrels are pests at Hamilton Lake. Deer at Pinto Lake – that's at the foot of Blackrock pass out in Mineral King.
Stories? Sure. True? Yep.
Is Mineral King worth it? You bet! More than worth it. I love that area. We did an awesome loop in October from Monarch Lakes over Sawtooth, down the valley and around to climb up Franklin Pass and back to the car – more rain, snow, hail and rain plus a totally crazy lightning storm way up in the clouds at 2 am that was noiseless but impressive. Cold, wet, but awesome. We were very happy to get that hot coffee with our pie at Silver City. Farewell Gap out into Golden Trout is another kind of awesome. This year we are going up to do some cross country out Mosquito/Eagle lakes way.
