Start the trail by entering toward the end of Stem Cell
and heading north along the edge of the wheat field. Cross the trail and head up hill on moderate switchbacks.
On the way down, you'll flow past several corners and drops and into two huge jumps that can be rolled or you can air it out 25 feet. Go as fast as you can for as much air as you can. Follow a few more flowy corners to the bottom, then drop into the ravine and over a ladder bridge/berm/ladder bridge system.
Continue out the bottom of the ravine for fun rollers, jumps, and flow.
