About this map

The Continental Divide serpentines across the northeastern corner of this 1958 survey, marking the high country of the Helena National Forest. The landscape is a complex of mining and ranching history, with the Northern Pacific railroad corridor following the Little Blackfoot River through the settlement of Avon. A notable inclusion is Blackfoot City (Ghost Town), once a bustling gold camp, situated along Ophir Creek near numerous Placer Mines and the Victory Mine.

Evidence of the area's mid-century industrial diversity is seen in the Shearing Plant near Mc Donald Gulch and a Microwave Relay Station atop Rocky Ridge. Significant mining activity is documented throughout the gulches, including the Luke Mine and Gimlet Mine located between Gravely Mountain and Luke Mountain. Local water systems like Spotted Dog Creek and Threemile Creek drain these mineral-rich highlands into the river valley below.
