Somewhat of a test of balance and focus, Four Wheel Drive moves up through the large scoop, into the hueco and finishes up the slab.
Although a hold broke at some point in 2007 (technically a key crystal on a sloper broke), the problem is still do-able and is roughly the same grade.
Located on a boulder about 20' almost directly south (towards the campgrounds) from Pink Crack, Four Wheel Drive faces north. Look for a large concave scoop with a flake in it that marks the start. Sit Start.
