Introduction

Background: 1

The rugged beauty of the Badlands draws visitors from around the world. These striking geologic deposits contain one of the world’s richest fossil beds. Ancient horses and rhinos once roamed here. The park’s 244,000 acres protect an expanse of mixed-grass prairie where bison, bighorn sheep, prairie dogs, and black-footed ferrets live today.

Nature

Ecology: 6

Located in southwestern South Dakota, Badlands National Park consists of 244,000 acres of sharply eroded buttes, pinnacles and spires surrounded by a mixed-grass prairie ecosystem . The mixed grass prairie is a transitional zone between the tall-grass prairie to the east and the short-grass prairie to the west. The buttes and spires of the park were formed through the geologic processes of deposition and erosion. The rocks of Badlands National Park were deposited as early as 75 million years ago and began eroding just 500,000 years ago. As erosion continues today, fossils buried in the rock slowly reveal themselves and park paleontologists study them to learn about ancient life in the area . Amid the prairies and buttes, numerous animals call the park home. There are many forms of wildlife in the Badlands, ranging from bison to butterflies and everything in betweeen.

Campgrounds

Cedar Pass Campground: 10

Cold running water, flush toilets, and covered picnic tables are available. A limited section of the campground is open during the winter months. Four campsites are available in the Cedar Pass Campground for organized groups with a designated leader.

Sage Creek Campground: 11

Bison often wander through this primitive campground, located on the west side of the park's North Unit. Access is located off of the Sage Creek Rim Road, an unpaved road that may temporarily close after winter storms and spring rains. The road provides limited turnarounds for large recreational vehicles. Camping is free of charge. Pit toilets and covered picnic tables are available, but no water is available on-site. A portion of the Sage Creek Campground is designated for horse use.
