Rimrock Ramble Professional Review and Guide
"Heart-pounding” is about the only word that could sum up this ride. The first mile winds along the top of the ridge and is filled with fun, fast singletrack, and some nice-sized rocks. Once the trail dumps you out into Morrison Run, it starts to get nice—nice and scary! Your technical skills will be tried to the utmost as you pick, choose, and slam your way down this gnarly streambed. Water washes over your rims and grit packs into your brakes as you try to stave off the tenacious pull of gravity. The ability to choose a solid line down this valley will be your only redemption.
As the stream nears its destination, the trail will peel off right and begin a series of short but extremely steep climbs. A signpost with the trail name marks the tiny singletrack that leads down to the Morrison campground. This is a great spot to stop and soak in this beautiful lake. Highlights: Lakeshore primitive campsites (walk, ride, or boat in only!), gnarly rocks, dense hemlock forest, beautiful lake vista, cold-air caves, rock climbing. Tread: technical singletrack in the first 2 miles gives way to wet and dry creekbeds for the next 4 miles; 3 more miles of technical singletrack lead to 3 miles of old logging roads."
