Looking Toward Greenfield Flat Trail

Greenfield Flat Trail - The greenfield Flat trail is an old road that begins at the end of Forest Service (FS) Road 646C.

The trail climbs gradually then steepens as it passes through a mature pine forest and comes out onto a wide flat ridge top, where there is a 360-degree view.

The trail travels through grasses and small aspens along this ridge, while on both sides of the trail, dense forest and low brush exist. This ridge also serves as a cattle driveway.

After crossing the ridge, the trail turns sharply and drops down onto the flats, which are an expansive, gently sloping grassland dotted with an occasional clump of subalpine fir and spruce.

Once on the flats, the trail turns east again and climbs up through the flats to a wide saddle where it ends at its junction with the Wilson Creek Trail.

This junction is not signed. The Wilson Creek Trail provides access to the Poison Creek Trail and the West Mountain Trail.

The unsigned trailhead is at the end of Forest Service (FS) Road 646C.
