After ascending up the standard Slant'n'Dicular
route along the northern edge of the Jumbo Mountain Trail System loop, you'll top out on the Grassy Knoll. From here, you can continue on the loop by going further up or turn left to descend this amazing ridgeline.
Along the route, you'll see The Plunge
off to your left that descends straight down the mountainside but if you stay on the trail you'll continue your descent to the central intersection called CC's Crossing that provides options for many other trails.
