Wizard Island Turns Upside Down in Crater Lake's Watery Mirror Exceptional depth and purity account for the lake's incomparable blue. Like a clear daytime sky, the waters reflect blue and vio let wave lengths strongly while absorbing other colors or transmitting them down ward. Aquatic moss, which needs light, grows at a record depth of 425 feet. Distance here proves deceptive. Wizard Island, seemingly close to shore, lies almost two miles out. Lodge and campsites of Rim Village occupy the foreground. Perched on a cliff 950 feet above the water, Crater Lake Lodge accommodates guests in 70 rooms and 22 cottages. The park also has four campgrounds. Some 400,000 persons visit Crater Lake yearly.
