The sea cliff above north Del Mar Dog Beach shows every sign of instability, including fresh piles of slide debris lined up along its base.

Another sign of instability for the less observant.

The small cave to the right was probably excavated by hydraulic or pneumatic overpressures generated when large high-tide waves bash the cliff face directly. One of several ways the cliffs here are undermined by the sea.

Guess the sandstone face looked pretty solid to her. She walked her dog back and forth right next to it for a good 10 minutes.

Of course, lots of people never look up. Maybe she didn't see all the telltale signs that the much softer upper part of the cliff face is actively crumbling.

To be fair, she didn't have the benefit of a fresh pile of slide debris right in front of her.

But her boyfriend did. Note the loosened material still waiting to fall above his head.

The slide risk isn't just theoretical. In 2018 or so, a slide buried and killed a family of 8 while they picnicked at the foot of a sea cliff a few miles north of here, totally without warning. Well, except for the nearby "stay back" signs like the one above.

There is that whole undermined sidewalk above his head! So, Darwin with his wide vaulting prefrontal dome & domer can present the ultimate award at any moment. Someone doing this also does similar things regularly, things like crossing the street while looking at a phone and using a hairdryer in the bathtub.

That's some serious erosion.
 
I was with my bike advocate, architect, friend Pete after handing out five-hundred postcards about the Holiday Lighted Bike ride at Santa's arrival by tugboat, when a mom came by with four kids, one a little baby on a sack at her chest. Seven years ago a young smart clean cut man came into the sporting goods store where I worked then. He wanted a bike for a girl he just met as a gift so they could ride togher. He had a budget and I showed him one that would fit. Then he brought in the lovely girl. She loved it and he gave it to her on the spot. She loved it. That is now the mom of four! Because of the surprise gift bike and the fun it made she married him and had his kids. Values are what we invest in. He took a risk and put a down payment on being active with her. What a pay-off! He was not seeking dark bars or hookups. He wanted to actively engage in the sun, with someone lovely.
