Assateague Island is a narrow barrier island that stretches along the coast of Maryland and Virginia. It is famous for its wild ponies, which have roamed the island for hundreds of years. No one knows for certain how these ponies arrived, but there are two popular theories. One theory suggests that the ponies are descendants of horses that survived a Spanish shipwreck long ago. Another idea is that early settlers brought the horses to graze on the island.
Life on Assateague Island is harsh for the ponies. The sandy soil supports only sparse grasses, and fresh water is limited. As a result, the ponies have adapted by eating salty plants and drinking from small ponds. They have shorter, stockier bodies compared to typical horses, which helps them survive the tough conditions.
Every summer, an exciting event called the Pony Swim takes place. Volunteers herd the ponies across a narrow channel from Assateague Island to nearby Chincoteague Island. There, many foals are auctioned to raise money for the local fire department and to control the pony population. This tradition attracts thousands of visitors each year, eager to watch the powerful animals swim through the water.
