The tours depart from Cleetwood Cove at the north end of the lake, and circle the lake in the counterclockwise direction, stopping at a dock at Governors Bay on the south side of Wizard Island. Looking up out of the crater of Wizard Island from the bottomĬurrent public access to Wizard Island is available only during the summer months when boat tours on Crater Lake are in operation. Its surface features and lack of a crater indicate that Merriam Cone formed under water. Although Merriam Cone rises about 1,400 feet (430 m) above the caldera floor, its summit is still 505 feet (154 m) below the average lake level. The highest of these cones, the only one to rise above the current lake level, is Wizard Island, which rises over 2,700 feet (820 m) above the lowest point on the caldera floor and the deepest point in the lake.Īnother large cinder cone, Merriam Cone, is in the northeast part of the lake. Following the cataclysmic caldera-forming eruption, which left a hole about 4,000 feet (1,200 m) deep where the mountain had once stood, a series of smaller eruptions over the next several hundred years formed several cinder cones on the caldera floor. Wizard Island was created after Mount Mazama, a large complex volcano, erupted violently approximately 7,700 years ago, forming its caldera which now contains Crater Lake.
