It's my SAR helmet, but I'm off duty.  This picture, taken by my friend Shannon, is of me on the phone while at a belay stance on the standard east face route of the Third Flatiron.  The temperature in Boulder (in the background) that day was over 100 degrees, so in this picture the temperature on the rock was 110+.  Some of the handholds were painfully hot, and by the end of the day we had both run out of water.
