Well we did the hike today. Got up a 4am made our way to the South Kiabab trailhead for a 5am start. My plans to try and beat the heat and go down and up Kiabab were quickly discarded. Kiabab was a shadeless inferno so we decided to return to the rim via Bright Angel. Glad we did, it was a 104 degrees at the river and still 103 at Indian Gardens. Drank tons and tons of water, drenched ourselves at every opportunity and snacked almost continuously. Spent two hours waiting for the trail to come into the shade at Indian Garden then finished the climb. Really tough day, but incredible place and views. We are glad we did it. 17.5 miles, 13.5 hours inclusive off waiting out the sun.
Well done, glad you came up the BA as there's no water anywhere on the S. Kaibab.
Visit the canyon again in the winter or very early spring, it's awesome then and somewhat temperate in the canyon even when ass-cold on the rim. Seeing a storm clearing off the rim and temple summits is just amazing.
I hope you are still sore and happy from your vigorous jaunt. Here's the latest from the National Weather Service, your hike was only a few degrees cooler than this current warning. Glad you made it out.
