Geo 365: June 20, Day 171: Rounded Gravel and Driftwood

The waves crashing against Yaquina head have created a unique beach on its south side: polished, monolithically basalt, pebbles and cobbles. In addition to the oddity of the beach, the sounds it makes are also weird. First, water splashing into it, and draining through can make some very odd rushing sounds. Second, walking on it makes strange grinding and squeaking noises. Like walking on sand, more energy is wasted on internal friction than actual locomotion, and the experience is more tiring than one expects.
