Beach combing #2
Many of our beaches in this area are accessible only by staircases. The bluffs have become extremely unstable and there are stories about people who've lost their lives while merely sitting on the beach, folks who've lost their homes, or suffered serious damage as a result of living right on the edge. I don't recall anyone thinking about all this when I was a kid, although I know it was a reality.
What I DO remember is that the bluffs didn't seem to be leaking so much water as they do these last many years. I can't help but wonder if this isn't a result of people over watering their yards and the resulting seepage. I think lots of people forget that this is a desert, not Hawaii.
Over the years, many measures have been taken to try to stabilize the bluffs. I suspect these large rocks are one such attempt. I have a question, if there's a geologist out there, reading this: what would have caused these very regular marks on these boulders? I took lots of photos, there are many more such examples, not all exactly identical. I am intensely curious. If anyone knows, please let me know!
