This is from the exit of the Left Fork of North Creek (aka "The Subway") slot canyon in Zion Natl. Park. An often photographed location for a good reason, it pretty unique (even in canyon county terms). The hike is a fairly miserable 8 mile round trip scramble up and down a river bed/flood zone with numerous river crossings and lots of boulder-hopping. It's worth it once you round the corner to a truly spectacular section of sandstone. I left a couple hours before sunrise to beat the mid-day rush and had the place to myself for a couple of hours before at least 20 others began crowding the narrow exit. It was a fun day, soon I hope to do the slot top down and explore the whole canyon.
