Sections of the dunes collapse. I stopped climbing them when I was sitting above my children and I was hit from behind by a collapse and pushed 5 feet forward. There was no warning, just sound and hit. I was not buried, but I realized how I could have been. I took my kids down off the dune.
There are sections of stairs left where the bottom sections have been washed away. Some days as it warms up, you hear sand sliding down, tiny trickles. I have a friend who saw a huge section collapse, all the way out to the water, with trees. He and another walker missed being buried by five minutes.
We walk the beach anyhow. This will collapse eventually but was standing on Saturday.
