Red Mountain Solar Eclipse

San Juan Mountains, Colorado | 2017

In August of 2017 a solar eclipse was visible over most of the United States; in southern Colorado it wasn't a total eclipse but was still quite interesting to witness, especially from about 13,000 feet up in the San Juans! I poked a bunch of pinholes in a sheet of paper and the eclipse was clearly visible in the light/shadows cast through the holes. Photo © copyright by Jack Brauer.
