I am a tad embarrassed to admit that I've never read anything by John Dos Passos (1896-1970), American writer and artist. He was a contemporary and one-time friend of Ernest Hemingway. Jean-Paul Sartre called Dos Passos "the greatest writer of our time."
On page 222 of Virginian Carr's biography, Dos Passos, A Life, she writes about the author's 1926 trek up the Outer Banks, including his stop at Ocracoke. After attending a square dance at the old Pamlico Inn, he and his companions set out walking up the beach in the moonlight. They passed a herd of wild ponies and "the silhouettes of hulls and masts of shipwrecks casting grotesque shadows upon the fine white sands. The sojourners counted some forty vessels in one area alone."
You can read the relevant excerpt from Carr's book here.
I'll look for one of Dos Passos' books. Maybe you'll want to read one also.
