The 120-m-thick Hutchinson Salt Member of the Permian Wellington Formation of central Kansas supports multiple industries. Composed of bedded halite, gypsum/anhydrite, and minor siliciclastic mudstone, it was deposited by shallow saline waters in a warm, dry climate. Underground salt mines access the purest horizon, producing salt that is distributed through the United States and Canada. The vast space left by mining supports a prosperous commercial storage enterprise and a popular underground tourist attraction. Vertical solution-mined caverns host the nation’s primary midcontinent liquid petroleum gas storage industry. This field trip will explore the origin and use of the Hutchinson Salt in core samples and subsurface outcrops while meeting in an underground salt cavern, and above ground at a solution-mined storage cavern.

The flat-lying sedimentary strata of the North American midcontinent are typically thought of as uniform and predictable. However, midcontinent geology contains a record of exciting geologic events and processes. The papers in this volume examine four geologic phenomena associated with the continental interior: Pennsylvanian and Permian cyclothems, the origin of a massive Permian salt deposit, Cretaceous kimberlite intrusions, and Quaternary glacial geology. The guides cover processes and events that are unique to the geology of Kansas and highlight important economic and rich historical influences of these geologic features.
