aka Waterfalls Canyon. Hidden behind Timbertop Mountain and Nagunt Mesa is an interesting canyon that makes a fine adventure on a long summer day. Two entrances are available: the Slickrock Pass start offers a big wall, technical, station to station rappel route suitable for a small party of expert canyoneers; while the North Pass start provides a dramatic 4th class slickrock couloir followed by two steep rappels – an interesting approach at a more moderate standard.
The canyon itself is narrow and lush, keeping a trickle of water even in drought conditions. A few rappels and a swim lead to the top of a huge, three-drop waterfall. From the bottom end, this canyon is known as Waterfalls Canyon. Bypassing the waterfall and descending the adjacent ridge, the delighted canyoneer passes below one of the world's largest arches (Kolob Arch) on her way to LaVerkin Creek. Then there's only the little matter of a 7 mile, 1000-foot gain (11 km, 280 m) slog back to the trailhead.
Either route can be done as a long day-canyon or as an overnight trip. However, humping bivy gear up the wooded ridge and down the rappels is a lot of work, and not recommended. The hike back to Lee Pass can be brutally hot in the summer.
