Timing is everything – a Grand Canyon adventure

Last May, three of us decided to hike from the North Rim of the Grand Canyon to the South Rim in one day. Now this is a 25-mile hike, down about 15 miles and 6000 feet to the Colorado River and then back up to the North Rim another 10 miles and about 5000 feet; a challenging hike at the best of times but the real difficulty is the temperature.
