Castaway cows.

Cape Lookout National Seashore on the Outer Banks has discovered three cows are roaming the national park, and it is believed they got there by swimming four to five miles across the Core Sound during Hurricane Dorian.

All three were living on Cedar Island when the hurricane generated a “mini tsunami” on Sept. 6, sweeping much of the wildlife off the island, including 28 wild horses that perished, officials say.

Cape Lookout Spokesman B. G. Horvat told McClatchy news group park staff spotted the first cow on the North Core barrier island about a month after the storm. The others revealed themselves in the past two weeks, and the trio are now grazing peacefully together on federal grass, he said.

Horvat believes they survived the amazing trip pushed by storm surge. Any farther, and they’d have drifted into the Atlantic, which happened to some of the wild horses that died.

Lucky cows!
