The El Dorado mountains, paralleling the west side of the Colorado River, were uplifted during the Miocene Basin & Range Uplift, about 15 million years ago. The northwestern part of the area is a wide, gentle slope of gravels that has been washed down from the mountains above. The rest of the area is higher and rugged with narrow drainages, thick vegetative cover and seclusion from the outside world. Desert Tortoise, scorpions, a multitude of reptiles including rattlesnakes and Gila Monsters, Desert bighorn Sheep and birds including Gambel's quail all make their home in the Eldorado Wilderness. The wilderness is jointly managed by the National Park Service and the Bureau of Land Management.
