About this map

Frontier Town sits along the Continental Divide in this late-century survey of the high mountain passage between Powell and Lewis and Clark Counties. The landscape is defined by its transit history and extractive roots, featuring the prominent MacDonald Pass and Priest Pass. These corridors have long served as vital crossings for both infrastructure and industry, evidenced by the numerous Prospect locations and mining operations like the Third Term Mine found tucked into the gulches.
