MISSOURI (KSNF/KODE) — A state park in Missouri is staking claim to the nickname “America’s Little Grand Canyon.”
Grand Gulf State Park, located in South Central Missouri (along the Missouri/Arkansas state line), is one of the natural wonders of the Ozarks. The highlight of the park is the collapsed cave system (one of the nation’s largest) known as the Grand Gulf. It stretches for nearly a mile between 130-foot-high walls, making it deeper than it is wide.
The cave’s roof forms one of the largest natural bridges in the state, spanning 200 feet with an opening 75 feet high and 50 feet wide.
Visitors of Missouri’s Little Grand Canyon will come across a variety of natural wonders. Inside the 322-acre park, boardwalks and overlooks have been installed so that visitors can get a view from the edge of the cliffs and descend partway into the canyon without endangering themselves or the environment. Many of the outdoor exhibits tell the story of the Grand Gulf and help park visitors understand how it was formed.
Visitors can also travel along several hiking trails, which all offer great views of the canyon from above. As a word of caution: There is no trail leading to the gulf’s bottom, so approach with caution if you attempt to go there.
While the cave is inaccessible now, in the late 1800s, early explorers entered it and discovered a very low ceiling and several small, white-eyeless fish.
By the 1920s, a severe storm washed many downed trees and other debris into the gulf, filling the cave and leaving it impenetrable.
In the early 1990s, a robot with a digging tool and a remote camera was able to make it into the cave, determining it was not feasible to gain access through the massive blockage. Even now, heavy rains will fill the gulf to depths exceeding 100 feet, with water slowly draining out over a period of weeks.
In 1971, Grand Gulf was designated a National Natural Landmark. In 1984 the property became a Missouri State Park through a donated lease with the Missouri Department of Natural Resources.
In July of 1986, a 60-acre portion of the L-A-D Foundation property was designated as a Missouri Natural Area.
