Mercedes DeMasi has been coming to Assateague Island National Seashore to camp for more than 20 years.
She books her favorite spot, nestled in the dunes between the ocean and the island’s famous wild horses, months in advance.
But this year, she said, she noticed her spot doesn’t quite look like it used to. “Things have changed a lot around here,” DeMasi said. “I've definitely noticed like the dunes eroding a lot."
Kelly Taylor with the National Park Service said most visitors don’t really think about sea level rise here on the island until they can’t find their favorite campsite. “They're like, ‘Number 14 is the best site,’ and they turn around and are like, ‘Ah, what happened?’"
