2014 Map of Ophir Creek

About this map

Quigley and McGillvary sit along the creek-carved drainages of the Helena National Forest in this 2014 topographic study of the Montana landscape. The map highlights the rugged intersection of the Powell and Lewis and Clark county lines, where high elevations like Black Mtn overlook deep-cut ravines including Illinois Gulch and Ohio Gulch. This modern survey documents a persistent network of mountain roads such as Ophir Creek Rd and Georgia Creek Rd that navigate the drainages of Sixmile Cr, Threemile Cr, and Ballarat Cr. Genealogists may find particular interest in the Blackfoot Cem, located near Illinois Ridge, while hydrologists can trace the many water sources feeding the Avon Valley, including Warm Spring Cr and Beaver Pond.
