Flooding in Supai Canyon
There have been a number of reports on the flooding in Supai Canyon, near the Grand Canyon this past weekend. I think the best description of the event and the subsequent rescues was from the AZ211 website which I found by way of the Arizona Geology Blog (quoted after the break). The flood was impressive. I hope the areas near Havassu Falls and Mooney Falls were not too heavily damaged. I was fortunate enough to hike and camp that location back in College, the travertine is just amazing and makes the water so green. Mooney Falls and the area downstream are particularly breathtaking.

Many reports I’ve seen attribute the flood the result of the failure of the Redlands Dam. But again, the Arizona Geology Blog quotes the National Park Service as saying that the dam is a minor one meant to create a pond for livestock and wasn’t a significant factor in the flooding. The latest reports I saw was that 11 hikers who were missing were located today (by way of Geology.com)
