A couple great sketched maps of Isla Hornos, from the old to the new to the newest. Getting closer!
One of the first maps to show Tierra del Fuego as its region, separate from the mainland. This was after the Horn (really, the Hoorn due to the Dutchmen that named it) was doubled for the first time, but prior to several other exploratory firsts including the Falklands being completely described.
A gorgeous sketch map of Isla Hornos and Cabo de Hornos, edging into the Drake Passage and the goal of the expedition. For more amazing versions, see http://onezillustration.com/projects/
