Crabtree Falls Illuminated by December Supermoon


Randy and Nancy led a hike up to Crabtree Falls on the night of the Supermoon.  This photograph is a reasonable approximation of how it looked to me.

[Since the color receptors (cones) in our eyes don't function in low light, we must use our rods only, and these more sensitive receptors have a much lower spatial acuity and don't register color.]
