Ascend Rock Creek Tr1509 to Rock Creek Tie Tr1538, followed by a swooping descent on Basalt Ridge Tr1515.
The toughest ascent of the ride is on the 2.4mi (1800', 14% grade) Rock Creek Tie Tr1538, although the switchbacks are mostly rideable.
Basalt Ridge Tr1515 can also be accessed from Minnow Ridge Orv Tr1524 or FR6210, using Minnow Creek Tr1539 (1000', 13% ascent) and Basalt Pass Tr1530 (1300', 25% ascent) to form an 8mi (3600' ascent) advanced-skills CW loop.
Add Chikamin Creek Orv Tr1534 to create a near-epic 18mi (6900' ascent) excursion, possibly the best area ride.
As with all trails where it is possible, please sign in at the trailhead, to help let the forest service know that mountainbikers are using the trail.
Ding: Although Orv are prohibited on these trails, mountainbikers are infrequent users as well, so the trail can become overgrown in late summer and maintenance can be as infrequent as well.
Wilderness Hiking: Rock Creek ascends to the base of Carne Mountain, with several great hiking trails in the Glacier Peak Wilderness Area.
Old Gib Tr1528 offers a rugged ridgeline route, over Estes Butte and Old Gib Mountain, to Carne Mountain.
The hike can be extended with Leroy Creek High Route Tr1512 and FR6200 is well suited for shuttling.
