Hiking around the Utah desert for hours when it was in the mid-90s in mid-May made my head hot. Walking in a slot canyon an idea came to me as I touched the cool sandstone cliffs on a three feet wide trail. My face would cool down if I rested it against the rock.
Rock facing did make me feel cooler.
Until the next group of hikers came by staring at my up close and personal moment with red sandstone on my face.
