McCroskey State Park Loop

Located about 20 miles north of Moscow, 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.

Trailhead On US-95 take the Skyline Drive exit. This is about 26 miles north of Moscow or 10 miles south of Tensed. The exit is located right on top of the hill. Head east on Skyline Drive for about a mile and park at the large vehicle turnaround. There is an old beer hall and restrooms at the parking lot. The trailhead begins on the other side of Skyline Drive.

    The first licensed beer hall in Benewah countyThe structure beside the restroom at the parking lot is the first tavern in Benewah county to have a beer license. It was actually located on Marsh Hill, along US-95, but had to be moved when that road was widened. Built in 1933, the building did not benefit from the move, as a downed pine tree took out a corner of the house.

    Much of the Lazy T trail meanders through dense forestThe start to the trail is on the opposite side of Skyline Drive, a trail called Lazy T Trail. It meanders through a mixed pine, fir, and cedar forest for just under 3 miles, crossing a few seasonal brooks in the process. The trail is a packed-dirt single-track and is fairly hemmed in by trees, though some mountain views open up occasionally. There are a couple of forks in the trail, but they are marked. The trail ends on a grassy logging road where you take a right and slight uphill towards a pretty camping spot near Skyline Drive (about at the 3-mile mark).

    View from Mineral MountainCross Skyline Drive and ascend quite steeply along a single-track that is not marked on the park’s map. It climbs the southern flank of Mineral Mountain and about two-thirds up the forest opens up and you’ll enjoy some nice views to the south. For a while the trail follows a level logging road, but eventually veers away and climbs again, along a ridge, and heads straight up to the mountaintop. Mineral Mountain formerly featured a lookout tower and now surprises with nice views and a picnic table.

    Logging road down north sideThe trail continues on the other side of the peak, leading down into the woods and a few lingering patches of snow. Now a single-track, the path crosses a saddle, which is also the county line, and spills out onto a logging road that provides sweeping views to the north. This side is tribal land, not state park land, and has been logged extensively. One really needs to cross the small knob to the left to get back to Skyline Drive, but there is no obvious trail and since it wasn’t clear whether the land was private or public we followed the logging road downhill in a north-easterly direction until it met up with another logging road, a little before the 5-mile marker. Take a left onto that logging road and follow it uphill back to Skyline Drive, which is at the 6-mile marker.

    Lone Pine picnic areaNext are three choices, to the left is Skyline Drive, to the right a logging road, and in the middle a single-track ascending a small knoll. They all lead to the same place, so we picked the single-track, which crossed the knoll in perhaps half a mile and emerged onto Skyline drive (there is one fork along the way; take a left). There is a burned area to the south providing decent views. Follow Skyline Drive for perhaps a quarter-mile, then take a left onto a wide logging road that leads to a picnic area, nice views, and an interpretive sign detailing the life of Mrs. McCroskey.

    View northwest across the PalouseA single-track, marked as Lone Pine Trail on the map and signed as Fireplace Trail, heads off westwards, paralleling Skyline Drive but staying well below the ridge. In about a mile the trail heads back up to the rim to a campground and picnic shelter called Fireplace Campground. Stay on Skyline Drive until you’re passed the campground, then take a right onto a logging road that straddles the ridge and provides phenomenal views to the north (the entire north side has been clearcut).

    A singletrack along the northwestern flank of Mission MountainAt the 9-mile marker the trail once again meets up with Skyline Drive and another interpretive sign, this time a 1955-newspaper article detailing McCorskey’s land donation. The single-track remains to the north of Skyline Drive, however, and parallels the road. It bypasses Mission Mountain, dropping down its northern flank and reemerges onto Skyline Drive at the 10-mile marker.

    After crossing Skyline Drive, this road leads south for a mile to the beginning of the Korth trailCross Skyline Drive and take the logging road that heads due south. After about a mile take the single-track that tumbles down into the woods to your left. Shortly it spills out onto another logging road, which is the beginning of the Korth Trail.

    A splendid example of a Buick Century. Are the bullet holes post or perimortem?Follow this logging road for the next 10 miles. It meanders along the mountainside, at first very broad and open, then narrowing and swallowed by woods. In fact, this first section of road could easily be traveled by car, but the narrower and deteriorating road clearly took its toll on the driving populace, as evidenced by several wrecks sprinkled throughout the woods (though, we mused, perhaps this was the result of a drive-by shooting, a particularly delicate operation on a single-lane overgrown forest road, that caused the assailant to follow the victim down into the depths of the forest, only to be crushed by toppling trees….). Anyway, the road does cross several gullies where you may find water, but late in summer it likely is dried up.

    Skyline Drive is a gravel road, single-handedly built by Virgil McCroskeyThe last quarter of the Korth Trail is on a logging road that clearly is heavily used and makes for poor hiking. The road leads back to Skyline Drive around the 22-mile mark. Then it’s downhill on Skyline Drive, a gravel road, back to the trailhead.

    Trailmap
    Not so great

    • Much of the trail is on gravel or logging roads
    • Trails are shared with motorbikes and ATVs


    Alternate Routes

    • There are many more trails (32 miles in total) along Skyline Drive, which follows the ridge for another 10 miles. Refer to the trailmap
