At the Pacific entrance to the Panama Canal are four islands that have played an important part of the Canal Zone and Panama's history. Pirates, seafarers, sailing ships, Pacific Mail steamships, quarantine station, the causeway, coastal artillery fortifications, research, fun and more. There are so many stories about these islands. Here are a few images as they were in the beginning of 1900. Photos and colorized post cards from the collection of Bob Karrer.
