History & News


courthouse exhibit
July 16, 2020
The Sweetwater County Historical Museum recently completed an enhanced exhibit at the County Courthouse in Green River entitled "Mapping Our History: Surveying & Engineering in Sweetwater County." The new exhibit is an expanded version of a previous display of surveying instruments, books, and other items that belonged to the late Richard (Dick) C. Day, a distinguished former employee of Sweetwater County.
Day was an acclaimed civil engineer, land surveyor, and longtime resident of Rock Springs. Thanks to the efforts of Wayne Johnson, his former employer and colleague, Day's collection was donated to the County Museum.
Shortly after the Day Exhibit initially opened, a second collection of surveying artifacts was donated by John T. Nelson, Sweetwater County’s first full-time county engineer. To accommodate Nelson's collection, the exhibit grew fourfold, from a small five-foot case into two 10-foot cases.
With the expansion, interpretive wall panels were added to the exhibit, featuring the history of surveying and engineering in Sweetwater County and the West. Contributors to the project’s content and research included Mary Dunnewald, Tom Crank, Wayne Johnson, John T. Nelson, Mark Kot, Gene Legerski, and County Commissioner Wally Johnson.
The exhibit is located in the hallway near the front entrance of the Sweetwater County Courthouse at 80 West Flaming Gorge Way in Green River. It may be viewed during business hours of 8:00 AM to 5:00 PM, Monday through Friday.
Due to COVID-13 restrictions, the public may only enter the Courthouse through the front entrance on Flaming Gorge Way and are asked to exit the 2nd floor west entrance on North 1st West. Visitors are asked to observe social distancing and face masks, while optional, are recommended.
The County Museum is located at 3 E. Flaming Gorge way in Green River is open. Summer hours are Monday through Saturday, 10:00AM to 6:00 PM, and closed on Sundays and national holidays. Admission is free.

Museum Director Brie Blasi said that full measures will be in place to ensure the safety of Museum visitors.

Only two groups or parties will be admitted to the gallery at a time. Once those group have completed their tour, the next can begin their own visit.

"Our goal is to keep the experience of a tour of the Museum as normal as possible for everyone," Blasi said. She encouraged anyone with questions to contact the Museum at (307) 872-6435 or via email at This email address is being protected from spambots. You need JavaScript enabled to view it..
