1958 Map of Essex Mountain

About this map

The Emigrant Trail cuts across this high desert landscape of Sweetwater County, marking a historic corridor of western movement through a region defined by complex drainage networks and volcanic landmarks. The terrain is characterized by the prominent rise of Essex Mountain and the distinct formation of Tule Butte, while the Middle Hay Hills and Steamboat Rim provide rugged vertical relief. Water is a critical and concentrated resource in this environment, found at isolated points such as Oz Yoke Springs, Marine Spring, and Hillside Springs. Settlement is sparse, represented by the Middle Hay Ranch and Bar X Ranch, reflecting a landscape dedicated to large-scale ranching. The presence of Pacific Creek and various washes like Alkali Wash illustrate the intermittent nature of water flow in the basin, while industrial activity is noted by a solitary Oil Well and two private airstrips, suggesting the remote logistics of mid-century Wyoming land use.
