We will spend another day at Yankee Harbor, a rocky cove on Greenwich Island. The American sealer, Nathaniel Palmer, discovered and named Yankee Harbor in 1820 when he sailed his 47-foot-long vessel, Hero, around the South Shetland Islands in search of good beaches and harbors for his sealing fleet. Several thousand pairs of Gentoo penguins will welcome you ashore. Also, here you can see whale bones as a reminder of the whalers who practiced outboard flensing in the early years of Antarctic whaling (1906-1925). Weddell seals are seen on beaches regularly.
