Geo 365: June 22, Day 173: Cobble Beach

The cobble beach on the north side of Yaquina Head can show some odd sorting patterns. In large part, these begin to make more sense as you look at where areas are protected from stronger wave action by rock masses, and think about how this protection changes with changing tide levels. However, the complete absence of a sand-sized fraction (okay, maybe not complete absence, but almost) tells you that the energy level here is pretty darned high, overall.
