Overview
The Boise Basin once contained a thriving network of mining towns and contained the Pacific Northwest’s largest city in Idaho City. Idaho City has several hundred residents with a wide scattering of rural homes near Centerville, Placerville, and Pioneerville.
Mineral Mountain is one of the more gentle peaks in the region, even by Boise Mountain standards. A jeep road winds it way from the Alder Creek Summit past Mineral Mountain and ends near Grimes Pass. The last 100 feet of the peak must be hiked, but most of the outing can be trail run, hiked, biked, or skied. The summit is covered with large Ponderosa Pines, and is one of the few summits in the area of this fully tree covered nature. At one time, the largest Yellow Pine (Ponderosa) in Idaho was found just south of this area.
