Elevation: 6,705 ft
Clifty Mountain is found on page 51. A P2K summit.
This peak, which has 2,165 feet of prominence, appears to be gaining in popularity as the population of northern Idaho grows. Here is another take on the access which updates the information in the book.
The Clifty Mountain Trail, FST-182 will take you from the trailhead to the summit in 1.5 miles. The trailhead is reached 18.0 miles southeast of Bonners Ferry via Twenty Mile Road FS-408 and Black Mountain Road FS-274 which will take you to the trailhead at saddle east of Black Mountain. This trail is reportedly in good shape.
