The Black Crack is a natural fissure in Canyonlands National Park. It is said that the White Rim Trail, where the crack is situated, was used by cowboys and miners in earlier times to get to the lower benches of Canyonlands. In 1918, it was made into a trail by a group of cattle ranchers, and it was widened by uranium miners in the 1950s. The crack is a natural formation, and its intimidating looks attract many people.

The Trail has now become one of the most interesting treks among tourists. If you happen to be here, don’t forget to check out the low cliffs on your right on your way back from the trek. There is a large alcove around 200 yards away from the trail with 2 holes in its roof. It is said that the flint flakes scattered across the wash in front of the alcove are remains from the stone age. These flakes don’t occur naturally but were used as tools by prehistoric men.
