While doing some casual salamander searching at Circle Creek near Seaside, I came upon a batch of salamander eggs underneath a large rock.
The size is just too large for anything but a salamander and the only three regularly occurring terrestrial salamanders in this part of the world are Ensatina, Dunn's Salamander and Western Red-backed Salamander. Of these, only Dunn's Salamander is known to lay eggs in the fall.
Dunn's Salamander (Plethodon dunni is a fairly common salamander of wet forest areas of the Oregon Coast Range.
