Arches National Park
"An intricate maze of fins with different hues of red rising up from deep ravines" could be one way to describe the Fiery Furnace. It is possible to hike into countless dead-end passages amoung the network of towering rock walls. Because of the complex arrangement of fins and canyons, one could spend several days hiking and climbing and still miss seeing much of what is in the Fiery Furnace.
At a span of 63 feet, Surprise Arch is the largest arch within the Fiery Furnace.
