Tsunami Travel Times

A tsunami that started off the coast of Japan would take about ten hours to cross the Pacific Ocean before it hit the coast of Los Angeles. You can find out out the estimated travel times of tsunamis in the Pacific Ocean, the Indian Ocean and the Atlantic Ocean on the Tsunami Travel Times map.

It's starting early this year (https://wiki.lspace.org/mediawiki/Glorious_Revolution) but it might serve as a reminder.

A lilac towel is also allowed.

And hard-boiled eggs.
In remembrance of The People's Republic of Treacle Mine Road, The People's Revolution of The Glorious Twenty-fifth of May and the much-loved Sir Terry Pratchett, I wear today a branch of lilac.

This is for all the morons who still believe the Earth is flat, despite this being proved false over 2000 years ago!

How the hell does anyone in the 21ts century, with even a hint of an education can still believe this crap?

Map of the Chatham, Mass. area, from a landmark work by Champlain, 1613

Samuel Champlain first came to America in 1603, and spent much of the next few years engaged in a series of voyages exploring the coasts of New England and Nova Scotia. He described his experiences and observations in Les Voyages du Sieur de Champlain (1613), which he published to build support for the settlement of New France. Les Voyages included two small-scale regional maps of the utmost importance as well as large-scale maps of harbors visited by Champlain, including this depiction of what is now Chatham on Cape Cod.

This first European visit to Chatham-denominated “Port Fortune” by Champlain–was a dismal failure, as related by Burden:

“After having left Beau Port (Gloucester), Champlain’s pinnace rounded Cap Blanc (Cape Cod) and became entrapped in the shoals off the coast in October 1606. They managed to make it into present day Stage Harbor near Chatham, Massachusetts, for repairs to the rudder. They spent two weeks here effecting repairs. This is the only place in New England that Champlain comments on for its beauty. At the end of their stay a few Frenchmen were murdered by the Indians overnight on shore. Punishment could not be meted out, so they left. After exploring Nantucket Sound Champlain returned to try to gain some revenge; however, yet more Frenchmen lost their lives. It was then decided to head straight back to Port Royal. Quite why such an illogical name for the harbor was chosen is unknown.” (Mapping of North America, p. 214)

This little map appears to show what are today known as Stage Harbor and the Oyster Pond at Chatham (with Chatham Harbor and Monomoy both out of view to the right and below). The details are a bit challenging to relate to a modern map, likely due both to Champlain’s primitive survey methods and to the shifting landscape of Cape Cod itself. Some soundings are given in the harbor; pictographs depict topographical features, native dwellings, and the unfortunate events that befell Champlain’s men; and numerous locations bear alphabetical labels keyed to an explanatory legend. These include “the dwellings of the savages and where they plow their land,” “great quantities of oysters,” “the cross we planted,” and “the place near the cross where our people were killed by the savages.”
