Crater lake in June weather.  Driving around the Rim Drive.  This view is from approximately SW.  See location I've Geo tagged in flickr.  This is the closest location to Wizards Island as one can drive to along the Rim Drive.
The magical Wizard's Island which is a small volcano that has magically risen  inside of a Volcano's crater.  I believe there are boat ramps which allows non motorized boats to enter the island's clear blue and a small spot of emerald water.
