Geo 730: April 25, Day 481: Pile O' Pillows

Looking almost straight down onto the pillow basalt beyond the sea wall (which can be seen along the lower margin of the photo) at Depoe Bay, it looks as if the clastic sedimentary component is, for practical purposes, non-existent at this location. I noted on Wednesday that the sediment seemed to be becoming a smaller portion of the mix, and if you go back over earlier days, you can see that there is an apparent trend, from south to north, for an increasing ratio of basalt to sandstone. This is another instance of a pattern I've noticed from photos, not on the spot, so it really ought to be "ground-truthed." That is, it's an excuse to get back to this town and see if the trend I've noticed from afar is reflected in reality.
