1995 Map of Mastodon Mountain

About this map

The St Joe River corridor defines the southern reaches of this landscape, where a Gaging Station monitors the flow near the mouth of Hoyt Creek. This mid-1990s survey by the U.S. Forest Service captures a high-elevation interior of the St Joe National Forest, a region dominated by steep drainage systems and prominent summits. Resource extraction and forest management are evident through the presence of the Franklin Mine in Slate Creek canyon and the unidentified Prospect X near Prospect Mountain. High points like Dunn Peak, which features the Nud Lookout, and Mastodon Mountain serve as primary landmarks for the Avery Ranger District. The terrain is deeply incised by numerous drainages, including Lumberjack Gulch and Daisy Gulch, illustrating the complex hydrology of the Shoshone County backcountry before the turn of the century.
