Geologic History of the Lakotas’ Sacred Hills
Oasis on the Plains
The Black Hills rise incongruously from surrounding prairies of the Great Plains. While the Plains Indians' main food source, bison, grazed in the open space of the prairies, the Black Hills provided such resources as wood, water, berries, shade, stone, minerals, and smaller prey. The hills are still important to the culture, with many sacred sites located here. The Black Hills cover an area 100 miles long and 50 miles wide that straddles the Wyoming-South Dakota border. Geologists call the formation a dome or uplift. This feature results from a mountain building event 80 million years ago called the Laramide Orogeny in which Precambian stone buried miles underground was pushed to the earth's surface. Upper,
Black Hills, Red Clays
Encircling the granite core of the Black Hills from inside out are the Madison limestone plateau, Red Valley, Dakota Hogback ridge, and an outer belt of mountains in the north. The Visitor Information Center is located in the Red Valley, also known as Redwater Valley, Red Beds and Red Racetrack. The last name refers to a Lakota account of a great running contest that caused the Black Hills to rise, spilling blood and staining the ground red. Notice the 200-300 million-year-old clays and shales around you that give the area its colorful name. Being extremely soft, this formation erodes easily, sculpting dramatic gullies and buttes. Interspersed deposits of bright white gypsum erode and dissolve even more quickly, leaving underground voids that collapse to create sinkholes like the Vore Buffalo Hunt.
A Ring of Mountains
The outermost ring of the Black Hills is a belt of mountains in the north. Some located nearby include: Sundance Mountain and the Bear Lodge Mountains to the west, the Black Buttes and Inyan Kara Mountain to the south, and Devils Tower and the Missouri Buttes to the northwest. Like the central peaks of the Black Hills, these are igneous rocks;
