A few weeks ago I headed up to photograph Antelope Canyon, a slot canyon in Navajo Nation, Arizona (a little northeast of the Grand Canyon). If you've never experienced these (or caves like it in Zion National Park in Utah), you may wish to consider doing so. Like the Grand Canyon nearby, these sandstone canyons were carved by thousands of years of running water. Photos cannot do the place justice -- the canyons are absolutely beautiful. Some of my favorite images appear below:
