Arches National Park has the densest concentration of natural stone arches in the world. There are over 2,000 documented arches in the park, plus pinnacles, balanced rocks, fins and other geologic formations. Some are more notable than others. Here is a sampling of some of the longest, tallest, and most famous rock formations in the park.
Arches' Rock Stars
With a light opening measured at 306 feet (93.3 meters), Landscape Arch has the longest span of any arch in North America. (Four arches in China now outrank Landscape in the claim for largest arch in the world.)
The southern span of Double Arch soars 112 feet (34 meters) above ground level in The Windows Area of the park. It is also the second-longest arch in the park, at 144 feet (44m) across.
Standing beneath Balanced Rock, it's hard to grasp its size. The massive sandstone boulder perched atop the pedestal is estimated to weigh 3,577 tons. That's the weight of an icebreaker ship or approximately 27 blue whales.
Without a doubt, Delicate Arch is the most famous natural stone arch in the world. Referred to as "The Arch" by many arriving visitors for whom it is No. 1 on their must-see lists, Delicate has an allure that is hard to explain but impossible to deny.
The light opening beneath Delicate Arch is 46 feet (14 m) high. The entire rock span is around 60 feet (18 m) tall.
