I made me get the heck out of the house earlier today for some photo ops in the canyon. Stopped in a parking lot in Calico Basin, I noticed this boulder teetering on the very top of a small mountain. At the bottom there is a small park with toilets, overhangs with small cooking areas and such. Lots of people there on a regular basis. How awful it would be if this or other boulders suddenly came tumbling down! Photographed with my Nikon D3300 and a Nikkor 70-300mm at full zoom. Waaaay up there!!
