Southeast of Eugene near Roseburg in the Umpqua National Forest, the North Crater Trail #1410 is a 9 mile cross country ski trail through open meadow.
The North Crater Trail begins at the Howlock parking area. It passes behind the horse corrals, crosses a snowmobile trail and then proceeds south through heavily timbered areas with occasional views of Diamond Lake. At about 1.1 miles there is a stream crossing (Spruce Creek) which could be tricky. At about 2.5 miles there is a downhill slope to your right and the trail continues close to the snowmobile trail for a short distance. The next big challenge is a gully (Camp Creek), past that you are behind the RV park and then the Summit Rock snowmobile trail (3.6 miles). A right turn here down the snowmobile trail will take you to the Pizza Parlor or continuing south for another 1.1 miles you will arrive at Hwy 230 near the South Diamond Sno-park. The trail makes two quick highway crossings, then proceeds 4 miles to the North Crater trailhead (elevation 5900).
To reach the Howlock Mountain Parking Area from the intersection of I-5 and SR 138 in Roseburg, go east on SR 138 for about 79 miles to Diamond Lake. Turn right on NFD 4795, parking is the first left.
