This gap, approximately ten miles west of Mills, is a shallow pass though a ridge that is now known as Emigrant Gap Ridge. During the emigration, the trail briefly divided into three routes at present-day Casper. Those following the more northerly route passed through Emigrant Gap after crossing the North Platte River via one of the ferries or bridges around Casper. The route was especially favored by those using the Mormon Ferry.
Although it wasnít always evident to the emigrants, Emigrant Gap marked the beginning of their gradual ascent up and over the Continental Divide at South Pass. From this point, the emigrants got a grand, sweeping view to the west. Today, the site is marked by a BLM interpretive panel.
