I was even wondering if there are any differences in the beaches at Nags Head or Kitty Hawk. Does it look and feel like the beach did before nourishment?
We were in South Nags Head in October and the sand was fine. Similarly after the previous nourishment in 2011 or so the sand was OK. Other than adding what felt like a mile to the walk from access to water I didn't notice much of a difference. I believe the sand for NH was screened and the dredges were located pretty far off shore when we saw them starting the project in the spring. I didn't notice anything obvious as far as additional shell deposits or sharp shells.
The idea of having killed off all the coquina clams, mole crabs, ghost crabs, etc, is understood.
I also didn't notice any more or less mole crabs although a few months had passed since nourishment completed and we arrived.
I did see someone post a comment last week that the sand in Nags Head was like mud and wondered if that was true.
That comment might need some explanation. My guess would be the texture of sand was like mud, i.e. perhaps it was really soupy, swallowed the feet when walking, and generally made things difficult for walking and driving. In October the sand felt a lot like my expectations of sand. In October there was definitely no mud or anything that wasn't expected present.
