Grand Canyon, March 2010: Four days of hiking covering 60 miles (and a couple miles vertical). Includes a one day Bright Angel hike from rim to the Colorado River and back, and another down the South Kaibab and across on the Tonto and up on the Bright Angel trails. The higher trails were ice covered and required crampons, those just below were very muddy, and the rest were dry. They were great! - Andy Speth.
