Known for its 2000 natural sandstone arches, Arches National Park was chosen to be Utah's state quarter under the America the Beautiful Quarters program.
The most famous of the eponymous sandstone structures is the Delicate Arch, depicted on Utah License Plates and on a special commemorative Utah stamp. Formed of Entrada sandstone, the arch is the result of countless years of gradual withering and erosion.
For those less enamored of freestanding support structures, the park has much to offer in the way of hiking and wildlife. The park is particularly popular with climbers, who clamor to conquer the variously sized structures. While, following Dean Potter's free (i.e., no support or protection) climb of the Delicate Arch, the NPS forbid climbing on any "named arch or natual bridge", many other structures are still open for such activities.
In terms of wildlife, the park is home to species as diverse as peregrin falcons, red foxes, rattlesnakes, sparrows and mountain lions. It's also home to desert stalwart plants like catcti, bunch grasses and juniper.
