Grand Falls in northern Arizona is called the "Muddiest Waterfall in the World." The above photo was taken in March of 1999. This waterfall was created when Meriam Crater produced a lava flow that dammed the Little Colorado River. The lava dam can be seen on the right side of the photo; the canyon runs to the left and the large basalt outcrop in the foreground is part of the lava flow. Soon a lake developed and eventually the water worked its way around the lava flow and back into the original channel (canyon) creating the waterfall. When visiting northern Arizona on a dry, windy spring day, you may see a cloud of dust rising up out of the high desert -- you've found Grand Falls.
