These shots were taken during an eight-day September 2013
NABS Arch Rally along the northern and central California
coast, from just north of Crescent City, close to the Oregon
state line, to Morro Bay.

gallery for arch pictures. Most of these pictures were made
along the coastline, and the rest inland - Yosemite,
Red Bluff, and Redding.
