 Nope, I'm not in the Sahara. You don't get frequent flyer miles by coming to the Kilpecker Sand Dunes in southwest Wyoming, the largest active dune fields in all of North America. And these dunes are found just a few miles north of Rock Springs, Wyoming. They offer a lot of wildlife habitat, tremendous recreational space and opportunity and great opportunities for energy exploration. The Kilpecker Dunes total 109,000 acres and can rise up to 150 feet with sharp ridgelines steep enough to really spoil your day if you make the mistake of tumbling off the back of one. The area is certainly one of the drier places on earth, but the location and high elevation of up to 8,000 feet means that most of the precipitation that does fall is snow. And that snow gets buried by the sand and turns into ice. Then in the summer, the ice melts and forms ponds between the dunes. But the dunes aren't just for wildlife, they're also a popular recreation spot. And if you're up to a good hike, you can check them out on foot. Plus there are some significant energy reserves in the area, but you can imagine the challenges that come with planning any sort of stationary infrastructure in the shifting sands of the Kilpecker Sand Dunes.
