Possibly one of the coolest named landmarks in a national park is Wizard Island which dominates the western rim of Crater Lake National Park. It sits there proudly rising out of the water with its Witches Cauldron crater sitting at the top to remind you it’s actually a remainder of a volcanic cinder cone. The island and crater were named by William G. Steel in 1885. He apparently decided the island looked like a wizards hat.
Some 7,700 years ago the 3,600 metre / 12,000 foot Mount Mazama volcano in the Cascade Range of Oregon is believed to have erupted and collapsed creating the massive volcanic crater that forms Crater Lake today (the National Parks Service states it erupted enough ash to cover all of Oregon in a layer 20cm / 8 inches thick!). Smaller eruptions occurred over the next several hundred years leaving cinder cones behind such as Wizard Island.
One thing is for sure, the island makes for a spectacular view from just about anywhere around the Crater Lake rim drive. Enjoy the scenery!
