Climb Route (Untimed): Start at Mountain Bike Parking lot. Climb up road to Upper Notorizer. Climb Upper Notorizer into Vedder Climbing Trail. Climb up Vedder Climbing Trail. Climb up road to entrance to the Den. The timed section will start at the top the Den. NO SHUTTLES!!!
The hikers have packed the snow down into a bumpy slick ice layer, some of which is covered with a thin layer of snow. Its hard riding up for sure but with good technical skills it can be done. I wouldn't suggest riding down it in such slippery conditions.
