Other summits located along the same ridge include the 4,045 ft (1,233 m) Round Mountain, the 4,924 ft (1,501 m) Cable Peak, the 4,852 ft (1,479 m) Shasta Butte, and the 4,377 ft (1,334 m) Blossom Mountain.
During the Prohibition Era Mica Peak was the site of numerous bootlegging operations. The mountainous and thickly forested terrain provided cover that allowed the bootleggers to hide their stills. Most were small, individual operations but some larger commercial endeavors existed as well. The mountain's location on the state line, which inconsistently demarcated in the area, made the location even more ideal for the illegal ventures as Idaho and Washington authorities could be easily tricked into believing the stills were located just outside of their jurisdiction.[3]
Mica Peak (Idaho)
Mica Peak or Signal Point—located in Kootenai County—is the higher of the two peaks with an elevation of 5,243 feet (1,598 m). State Line is the closest city at seven miles (11 km) away.
Mica Peak (Washington)—located in Spokane County—is the lower of the two peaks with an elevation of 5,209 feet (1,588 m).
The mountain is the southernmost peak in the Selkirk range.[10] The peak is home to the now-decommissioned Mica Peak Air Force Station. The northern slopes are drained by Saltese Creek. The mountain dominates the view to the east and southeast from the city of Spokane Valley.
