This weekend I saw a complete 1603 edition of Theatrum Orbis Terrarum by Abraham Ortelius in the Connecting Seas exhibit at the Getty Museum. I never thought I’d see one in person. The editions after 1589 contain this lovely map of the Pacific Ocean, including an imaginary continent of Terra Australis (Australia was not seen by Europeans until 1606).
A map of the Panama Canal two years prior to opening, 1912
The Western Hemisphere, by John Cary, 1799
This map shows the explorations of Captain Cook to Hawaii (or Sandwich Isles), and the borders of the United States prior to the Louisiana Purchase, leading only to the Mississippi River. It rather optimistically shows Alaska and California (or New Albion) as territories belonging to the United Kingdom.
My friend Robert saw this Orca pod near Anacapa Island today.
John Nelson handsomely visualized the Ring of Fire in this map of global earthquakes since 1898. This is the polar projection of a more common image floating around the Internet.
(I tried, but I simply could not discover when the term “Ring of Fire” was first used to describe seismic activity around the Pacific Ocean.)
