Gitchie Manitou State Preserve, Nature reserve in Sioux Township, Iowa, US.
Gitchie Manitou State Preserve is a nature reserve in Sioux Township in northwestern Iowa featuring wooded sections, grasslands, and distinctive pink quartzite rock formations. The preserve covers roughly 37 acres and brings together different landscapes in one location.
The land came into state ownership in 1916 when it was first used for quarrying stone. Later the focus shifted to environmental protection and conservation instead of industrial use.
The name comes from Anishinaabe tradition, meaning 'Great Spirit' in their language. Visitors walking through the preserve can feel this cultural connection to the land that indigenous peoples have valued for generations.
The preserve opens at 4:00 AM and closes at 10:30 PM daily, managed by the Department of Natural Resources. Hiking trails are available for exploration, though visitors should come prepared for uneven terrain and outdoor conditions.
The site contains some of Iowa's oldest rock formations, Sioux quartzite that is roughly 1.6 billion years old. These ancient stone layers are rarely visible at the surface, making them noteworthy for nature enthusiasts.
