Here are a couple of the "basic" aid stations from Pinhoti.
Some of the aid stations at Wasatch were just as basic as you will see below. Again, most pictures are from Chihping Fu of Fremont, California. I did get his approval to use them. Thank you, Chihping. He is running the Bear 100 this year, which I had planned on running until Saturday. I received an email from The Tahoe Rim Trail 100 that slots had been added and everyone on the waiting list could register. I registered immediately.
At Wasatch, Most of the aid stations are very hard to reach. Some, like Grobbin's, Swallow Rock and Pot Bottom require serious four wheel drive vehicles. Rock Springs requires carrying everything in, along a miserable and very steep 2 mile long ATV trail. Almost all are very remote and require a drive up 8 or 10 miles of steep, dirt roads.
