New WSGS Pamphlet Highlights Seminoe State Park's Geology


The Wyoming State Geological Survey (WSGS) has released a new publication about the geology in Seminoe State Park in south-central Wyoming. The pamphlet highlights the park’s rock formations, sand dunes, and hydrogeology.

"Seminoe State Park has some of the most spectacular geology in Wyoming,” says WSGS Director, Dr. Erin Campbell. “It's rare to have such a complete geologic section, from Precambrian to Cretaceous rocks, so beautifully exposed and easily accessible." 

Readers of the "Geology of Seminoe State Park" pamphlet will learn that the area’s oldest rocks – granite and other metamorphic rocks – are at the north end of the park and make up the core of the Seminoe Mountains.

They will also learn that Seminoe Reservoir can hold more than one million acre-feet of water (1 acre-foot=326,000 gallons), most of which originates as snowpack in the nearby Medicine Bow, Sierra Madre, and Shirley mountains. The reservoir’s largest inflow is the North Platte River, which is an important tributary to the Missouri-Mississippi River System and a major source of municipal water for several Wyoming cities. 

The pamphlet is the second in a series about the geology of Wyoming’s state parks. The first focuses on Curt Gowdy State Park in the southeastern corner of the state.

"The WSGS is pleased to provide these geology pamphlets for the state parks,” says Campbell. “We hope they will help increase visitation to the parks, as well as help visitors understand the geology around them."

The pamphlets are free and available at the WSGS office on the University of Wyoming campus in Laramie, as a download from the agency’s website, and at their respective park’s visitor centers. Pamphlets now in production will focus on Glendo and Guernsey (eastern Wyoming), Buffalo Bill (northwestern Wyoming), and Keyhole (northeastern Wyoming).
