1950 Map of Harrison

About this map

Harrison and Pony serve as the primary hubs in this Madison County landscape, where the agricultural plains of the Antelope area meet the mining-rich slopes of the Bacco Root Mountains. The 1950 field check reveals an economy deeply rooted in both extraction and land management, evidenced by the cluster of workings like the Garnet Gold Mine and the Atlantic and Pacific Mine near the Deerlodge National Forest boundary. The presence of the Indiana University Geology Field Sta highlights the region's importance for scientific study, while the Northern Pacific railroad provides the essential link for the local Harrison Mill. Higher elevations are punctuated by numerous alpine waters, including Hollow Top Lake and Branham Lakes, alongside the Potosi Ranger Station and the nearby Potosi Hot Springs. This period captures the Missouri River Basin development era, as noted in the margin, reflecting a landscape of active placer mining and established ranching operations like the Springside Ranch.
