Fort Sublette coming soon!

Thanks to a very generous donation from the Gooch Family and a matching grant from Sublette County, the Museum of the Mountain Man is building an 1830s-era fort to be named Fort Sublette. The Fort will expand the Museum’s living history programs, providing opportunities for demonstrations and interpretation throughout the summer. It will also strengthen the partnership with the American Mountain Men (AMM) who have provided living history interpretation during Green River Rendezvous and Living History Days for 25 years.

Dirt work to prepare the site for construction will be completed this fall. During the winter, cabins and blockhouses will be built off site and moved to the fort site in the spring and summer of 2026. When complete the site will include a 100 ft by 100 ft log palisade wall with a gate opening onto the large lawn at the Museum. If all goes as planned, Fort Sublette will be ready to welcome visitors in time for Rendezvous in July 2026.
