This week in 1600, South America experienced the most violent volcanic eruption in its recorded history. The volcano known as Huaynaputina, in Peru, exploded, and the impact was global. The surrounding area was devastated, of course – much of it buried in six feet of volcanic ash and rock. But the eruption also altered global
William Henry Harrison, America’s 9th President, was born this week in 1773. Harrison probably would not be pleased to learn his greatest legacy: establishing the system for presidential succession, by dying in office.
