Sand Creek

Sand Creek is a river and natural landmark in Wyoming known for its exposed sandstone formations shaped by erosion. The waterway cuts through layers of cross-bedded rock, revealing geological patterns visible throughout the canyon walls and streambeds.

The National Park Service designated this location as a National Natural Landmark in 1984 to protect its geological features. The designation recognized the scientific importance of the sandstone formations and erosion patterns found here.

Indigenous communities historically relied on Sand Creek's resources, establishing connections through hunting and gathering activities in the surrounding territory.

Multiple trails run along the creek and can be accessed year-round, though checking weather conditions beforehand helps plan your visit. Seasonal conditions affect trail accessibility and water levels in the canyon.

The sandstone formations here serve as a reference point for studying North American sandstone geology and erosion patterns. Researchers use the visible layers to understand how water shapes rock over time.
