Some places are just off limits in summertime. The canyons feeding into the Colorado River from western Grand Canyon on down towards Parker, AZ are all in that category. This is White Rock Canyon, in Lake Mead National Recreation Area, just below Hoover Dam. Just like nearby canyons, the gravel in the bottom is your trail, the grade is very light, and the chances of wanting to take out your camera are very good.
You will find this photo along with the work of others on Leanne Cole’s site. There are also instructions on how to join in every week.
