Stonewall is a one-way trail in the Mammoth Bar OHV park. My favorite way to access this trail is after finishing culvert, head into the OHV as though you're heading to confluence. Instead of going right to confluence, turn left and head up the wide dirt road. This climb is the old stagecoach road and has a few spots with a decent view.

Compared to the fast flowing nature of culvert, stonewall feels like an exciting step up. Get a bit of a running start into the start of the trail as a bit of momentum helps keep your speed up for the first short uphill, then get ready for a ride. The trail immediately gets much steeper and chunkier than anything on culvert or confluence. At low speeds, it is easily manageable, but careful if you're pushing yourself, this rollercoaster goes straight into a 180 right hander that requires a hefty handful of brakes to negotiate. Just after this is a steep little pedal, keep your speed up, but be ready to dump gears. After this crest the trail drops into a steep left that hurls you into stonewalls best. Fast and flowy, with rollercoaster like drops and berms, broken a few times by odd off cambers and one rocky left that tends to push people safely off trail. A few more fun turns and you drop back to a double track that often has motorcycles and quads on operational days.

Go down to the right a bit, and choose between Rocky Trail(1/8th mile rock garden), or bombing the fire road to the bottom. Enjoy the climb out It's short, but very steep.
