Captain Clarence Dutton was the next man to make a discovery at Crater Lake. Dutton commanded a U.S. Geological Survey party which carried the Cleetwood, a half-ton survey boat, up the steep slopes of the mountain then lowered it to the lake. From the stern of the Cleetwood, a piece of pipe on the end of a spool of piano wire sounded the depth of the lake at 168 differnt points. Dutton's soundings of 1,996 feet were amazingly close to the sonar readings made in 1959 that established the lake's deepest point at 1,932 feet.

William Gladstone Steel devoted his life and fortune to the establishment and management of Crater Lake National Park. His preoccupation with the lake began in 1870. In his efforts to bring recognition to the park, he participated in lake surveys that provided scientific support. He named many of the lake's landmarks, including Wizard Island, Llao Rock, and Skell Head. Steel's dream was realized on May 22, 1902 when President Theodore Roosevelt signed the bill giving Crater Lake national park status. And because of Steel's involvement, Crater Lake Lodge was opened in 1915 and the Rim Drive was completed in 1918.

Crater Lake National Park is fast approaching its 100th birthday. The celebration of one of our nation's oldest parks is a testament to the courage and determination of William G. Steel and the countless others who have been involved in the preservation of this national treasure. In looking to the future appreciation and preservation of this park, knowledge of its history and origins are imperative in keeping with the tradition of Crater Lake's unique past.
