The gravel covering of this unique Pogonomyrmex salinus nest, extended approximately 1 m / 39 inches on its longest axis. The mound takes the form of a low dome built around a large central rock. Mineral deposits abundant in this area of central Washington state are responsible for the sprinkling of white particles amongst the gravel, and for the white rock face.
