Here's a little more info I found while researching:
primitive camping, no established campgrounds (just like DAA said).
Weather is unpredictable, so be prepared for rain/thunder in the afternoon. If it doesn't rain, even better. If it does rain, we'll be prepared.
Hazards in the Uintas (mainly as it applies to backpackers, but it's worth us paying attention)
Lightning occasionally kills people in the Uintas. It's a serious threat, especially above tree line. If a storm starts to build, take cover. Don't wait until you see lightning - by then it might be too late. Get off the peak or ridge. Head for lower ground. Don't hide under a tree which stands by itself; but you can take refuge under a grove of trees off the side of a ridge.
Hypothermia can also be a killer. Be prepared for harsh weather. Bring clothing and gear that protects against rain - it rains almost every day in the high country. It often snows and hails, even in August. The weather can change from hot to freezing cold within just a few minutes. If you get wet and cold then do whatever it takes to get dry and warm. Put up your tent. Build a fire. Drink warm soup. Spending the night in a wet sleeping bag can be more than just uncomfortable - it can be dangerous.
Sunburn is a common problem when hiking at high elevations. The atmosphere is thin and does not filter the sun's rays, so people bum quickly. Wear a hat and sunscreen.
Mosquitoes are public enemy number one in the Uintas. They are everywhere, and they can drive you crazy. Bring strong repellent - it really helps.
Black bears occasionally cause concern at some campgrounds at mid-elevations. Watch for advisories. Never leave food or garbage around camp, and don't keep food in your tent.
Moose can also be dangerous. They are often seen along the rivers and in marshy areas. Don't try to approach a moose. Pay attention and never walk between a cow moose and her calf.
