The 11 Bizarre, Wild, And Downright Weird Wyoming Attractions You Gotta See

It may be surprising enough to find a desert oasis in the mountainous state of Wyoming, but that's not even the half of it. The sand dunes in this desert sing. The grains of sand in the Killpecker dunes are smoother than your everyday run-of-the-mill sand. As the round, polished grains move against each other, either when people walk on them or the wind blows over them, it produces a whistling sound. It's a phenomenon that happens in only 7 locations in the world, and Wyoming is one of them.

As long as you're at the Killpecker Dunes, you may as well check out the other oddity the site has to offer. Boar's Tusk is one of the few variations of the mostly flat terrain of the desert area, so you're not likely to miss it. It looks like a giant tooth (thus, the name), but it's really what's left of an extinct volcano.

The residents of Douglas are particularly fond of Wyoming's unofficial state mammal, so much so that they've erected not one but two of the largest monuments in the world to the arguably mythical creatures.

With Douglas and Dubois on opposite sides of the state, you have equal opportunity to see a big jackalope no matter where you are. The one in Dubois is a huge stuffed creature inside a convenience store. It's sporting a saddle so visitors can climb aboard and have their pictures taken for posterity.

The Popo Agie River runs through Sinks Canyon, but it does more than flow. It actually disappears into a cave where it seems to end abruptly. It took scientific tests to find out that the river doesn't truly vanish, but re-emerges some distance away in a huge pool known as the Rise. There's still an unsolved mystery, however. The Rise gets filled with more water than comes out of the Sink, and no one has yet figured out where the excess water comes from.

Right along I-80, near where the railroad was built by the tiny town of Buford, is an oddity over a century old. It's there where railroad workers found a tree growing out of a crack in a boulder. It was fascinating enough back then for the crew to alter the railway path slightly to allow the determined little tree to continue growing where Nature had planted it, and it's still there today.

The stretch of HWY-89 that serves as the gateway to Afton is marked by the largest elkhorn arch in the world. Rising 18 feet high and spanning 75 feet across, it took more than 3,000 antlers to create this iconic Wyoming attraction.

Out in the middle of nowhere, along North Fork Highway near Wapiti, stands a Big Boy statue. No one knows where it came from or why. It simply appeared in the summer of 2013, concrete pedestal and all, with no explanation.
