All three forks of Leprechaun in one day. Not difficult to do at all when exiting at the junction.
Be careful because the brief descriptions provided here lack any detail. These are not difficult canyons, but are far from easy walk through either. Also, the easiest access (sans driving) is to walk up the slickrock from the highway.
I went in from the bottom in the early 1990's and down from the top of both forks in 2003. The right fork was at the "freeze fest" at North Wash with Steve Ramras.
