Agave Americana


Michael S Nelson, MD

This photograph was taken with a Nikon J1 during a springtime hike in a portion of the Carrizo Gorge, east of San Diego, CA. A cold front had just blown through, leaving behind a crystalline blue sky, total solitude, and excellent light and contrast for capturing the magnificent landscape.

Dr Nelson is a Pediatrician at the Otay Mesa Office and Medical Director of the Cleft Lip and Palate Clinic in the Department of Pediatrics in San Diego, CA.
