Scope and content
- In 1902, Congress decided that Crater Lake and its surrounding 180,000 acres were to be "dedicated and set apart forever as a public park or pleasure ground for the benefit and enjoyment of the people of the United States." It is the sixth oldest national park. The lake was formed after the collapse of an ancient volcano, posthumously named Mount Mazama. This volcano violently erupted approximately 7,700 years ago. That eruption was 42 times as powerful as the 1980 eruption of Mt. St. Helens. The basin or caldera was formed after the top 5,000 feet of the volcano collapsed. Subsequent lava flows sealed the bottom, allowing the caldera to fill with approximately 4.6 trillion gallons of water from rainfall and snow melt, to create the seventh deepest lake in the world at 1,932 feet. The rock formation shown on the card was so named because it resembles a ship. circa 1909.
