1894 Map of Idaho Basin

About this map

Idaho City stands as the central hub of this late 19th-century reconnaissance of the Idaho Basin, a region defined by its rugged topography and early mining infrastructure. Surveyed in 1892, the map documents a cluster of significant settlements including Placerville, Centerville, and Pioneerville, all interconnected by a network of gulches and creeks that drove the local economy. The drainage patterns of Mores Creek and Grimes Creek are charted in high detail, illustrating how the landscape dictated the placement of sites like Warm Springs and the Halfway House. To the southeast, the terrain opens into Smith Prairie near the confluence of the North Fork Boise River and Middle Fork Boise River. The placement of Quartzburg and numerous named gulches like Slaughter House Gulch and Ophir Creek provides a clear view of the territorial era's footprint before later development reshaped these mountain communities.
