1915 Map of Sunnyside

About this map

The Denver and Rio Grande Western railroad corridor anchors the southern edge of this survey, following the drainage of Grassy Trail Creek as it moves through the high desert of Carbon County. This landscape is defined by the massive verticality of West Ridge and Patmos Mountain, where deep drainage systems like Whitmore Canyon and Horse Canyon carve through the Book Cliffs formation. At the base of these heights, Pierson Ranch provides a rare marker of early 20th-century settlement in an area largely characterized by industrial and ranching potential. The high-altitude terrain is marked by peaks such as Mt Bartles and Bruin Pt, which overlook a network of seasonal water sources including Willow Spring and North Spring. This map captures the region's topography just as the coal-rich canyons were being developed into critical hubs for the Utah rail economy.
