Fremont County, Wyoming

Fremont County is in west central Wyoming. This is the home of the Wind River Indian Reservation (home of the Shoshone and Arapaho Nations) and the grave of Sacagawea. There's a lot of the Bridger-Teton National Forest here, too. Named in honor of explorer John C. Fremont, Fremont County was formally organized in 1884 and contains 9,182 square miles of land and 84 square miles of water. The county seat is Lander.

South Pass is in southwestern Fremont County. This is where the Oregon, California and Mormon Pioneer Trails crossed the Continental Divide. The rise and fall from the pass are so gentle that most folks didn't even know they had crossed from one ocean drainage to the other. That's in serious contrast to Togwotee Pass at the northwestern edge of Fremont County. Togwotee is in between the Absaroka Mountains to the north and the Wind River Range to the south. The highest (and sharpest) mountains in Wyoming are here.
