A short, but technical, canyoneering route in Zion National Park turned deadly when heavy thunderstorms filled the slot canyon with water, killing at least five hikers while two others were still missing Wednesday.

One million visitors. That seems like a lot for an entire year, and definitely a lot in one month for Yellowstone National Park, which came within 19,000-odd visitors of reaching 1 million during July.

It's not often that I'm stopped in my tracks by a product. After a quick loop through our local REI in Salt Lake City a while back, I headed over to International Mountain Equipment just a few doors away. This small shop is the real deal for climbers and outdoors people. It's the type of store that sells things you'll use for decades until they wear out. So, as I looked over some climbing nuts and harnesses I spotted a book on the glass counter: the 3D Atlas of Zion National Park in Utah. Sounded interesting.
