Big Basin Prairie Preserve

The Big Basin Prairie Preserve in Kansas encompasses a significant sinkhole system, most notably the mile-wide Big Basin and the water-filled St. Jacob's Well. These geological features, formed by sinkhole activity, are historically notable as resting places for the Northern Cheyenne and landmarks for cattle drives. The preserve is a designated National Natural Landmark, managed to protect its unique landscape and wildlife.

Key Facts

  • The Big Basin is approximately one mile in diameter and 100 feet deep.
  • St. Jacob's Well is a water-filled sinkhole within the Little Basin.
  • St. Jacob's Well is 84 feet wide and 58 feet deep, and has never been known to go dry.
  • The preserve was designated a National Natural Landmark in 1978.
  • The area was a historical campsite for the Northern Cheyenne during their 1878 exodus.
  • The Big Basin was used as a landmark and watering site for northbound cattle drives.

About Big Basin Prairie Preserve

The Big Basin Prairie Preserve, situated in the Red Hills of Clark County, Kansas, is a significant natural area managed by the Kansas Department of Wildlife and Parks. The preserve's most notable geological features are the Big Basin, a vast, mile-wide depression resembling a crater, and St. Jacob's Well, a water-filled sinkhole located within the smaller Little Basin. These formations, resulting from sinkhole activity, have a rich history predating their preservation as a nature preserve.

Geological Significance

The Big Basin is described as being approximately a mile in diameter and historically noted to be around 100 feet deep. It lacks an outlet, leading to occasional shallow ponding on its floor. Adjacent to it is the Little Basin, and on the rim of the Little Basin lies St. Jacob's Well. Research has determined St. Jacob's Well to be 84 feet wide and 58 feet deep, and it is known for never going dry. The floor of the Little Basin itself exhibits shallow depressions that are believed to be the healed remnants of earlier sinkholes, suggesting a dynamic geological past.

Historical Context

Historically, the area served as a resting place for the Northern Cheyenne during their exodus in the fall of 1878. It was also utilized as a crucial landmark and watering site for northward cattle drives originating from Texas and heading to Kansas railroads. Willard D. Johnson of the United States Geological Survey documented the Big Basin in 1901, providing early scientific observations of its dimensions and characteristics.

Preservation and Public Access

Efforts to preserve the land that now constitutes the Big Basin Prairie Preserve began in earnest in the early 1970s. Mrs. C.G. "Janie" Stein was instrumental in these efforts, forming the Big Basin Foundation and working with various agencies and individuals to protect the area, particularly for its bison and pronghorn populations. The Nature Conservancy was involved in facilitating the land's acquisition, which occurred in 1974, with the condition that it be operated as a nature preserve. In recognition of its natural importance, the preserve was designated a National Natural Landmark in December 1978. The Big Basin Prairie Preserve is open to the public and is stocked with buffalo, making it a destination for observing both unique geology and wildlife.
