Located about 20 miles north of Moscow, ID, McCroskey State Park stretches along Skyline Ridge to the Washington state line. The land was donated to the Park Service by Virgil McCroskey in 1955. Worried about maintenance cost, the state of Idaho only accepted on the condition that McCroskey maintain the land at his own expense for 15 years. He accepted, maintained the property for 15 years, and died a few weeks later at age 93. The park is named after his mother, Mary Minerva McCroskey. The loop trail ascends the southeastern flank of Mineral Mountain in the easternmost section of the park, then follows the ridge to Mission Mountain, and completes the loop by returning via the Korth Trail, a logging road that contours along the side of the ridge.
