Grand Gulf State Park, Natural canyon formation in Oregon County, Missouri, US
Grand Gulf State Park is a deep canyon in Missouri's Ozark region with sheer rock walls and a natural stone bridge overhead. The site formed through underground water dissolving limestone over millennia, creating a dramatic geological formation.
The canyon formed millions of years ago through natural processes that shaped the Ozark landscape. The state recognized its importance in the 1980s and took steps to protect and manage the site as a public park.
The park stands as a research location for understanding karst topography and the natural processes that shaped the Ozark region throughout geological periods.
Two walking trails take you through the canyon and offer different viewpoints of the rock formations and natural bridge. Wear sturdy shoes since the paths are uneven and can become slippery after rain.
Rainwater seeping into the canyon floor flows underground for nine miles and emerges in Arkansas within a few days. This hidden underground route connects two states through nature's plumbing system.
