Call it a blatant plug for Oregon scenery, this view is available less than 20 miles from the Portland International Airport, and I-84 is visible … way down below.

Make sure Candelaria has minute lobes…

There are several other granular crustose lichens of the same color. Generally I can make out a few intact lobes in your photo, strongly suggesting Candelaria (even that can be an incorrect deduction), but the one in this photo look purely powdery. Other possibilities are: Chrysothrix (purely powdery or “leprose”), Candelariella efflorescens (only bark, so we can rule it out for this specimen), and Caloplaca (reacts K+ red and is typically oranger).
