1975 Map of Cornish Gulch

About this map

Deerlodge National Forest encompasses the majority of this mid-1970s landscape, where the Sapphire Mountains rise sharply above a dense network of drainages. The area is defined by its deep alpine gulches, ranging from the prominent Cornish Gulch and Ginger Gulch to the complex systems of the North and South Forks. Early industrial activity is visible at the Silver King Mine and through various prospects scattered near Quartz Gulch, indicating the mineral interests that shaped this portion of Granite County. Transportation through this terrain is limited to isolated crossings like Gillies Bridge and a network of jeep trails and the Spring Trail. The drainage patterns are particularly intricate, with Rock Creek and its many tributaries, including Stony Creek and Sluice Gulch, carving through the timbered slopes and reaching prominent peaks like Ram Mountain.
