William Gladstone Steel devoted his life and fortune to the establishment and management of a national park at Crater Lake. 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.
With the help of geologist Clarence Dutton, Steel organized a USGS expedition to study the lake in 1886. The party 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 different points. Their deepest sounding, 1,996 feet (608 m), was very close to the modern official depth of 1,949 feet (594 m) made in 2000 by sonar.[4] At the same time, a topographer surveyed the area and created the first professional map of the Crater Lake area.
Partly based on data from the expedition and lobbying from Steel and others, Crater Lake National Park was established May 22, 1902, by President Theodore Roosevelt. And because of Steel's involvement, Crater Lake Lodge was opened in 1915 and the Rim Drive was completed in 1918.[3]
Highways were later built to the park to help facilitate tourism. The 1929 edition of O Ranger! described access and facilities available by then:
Crater Lake National Park is reached by train on the Southern Pacific Railroad lines into Medford and Klamath Falls, at which stops motor stages make the short trip to the park. A hotel on the rim of the lake offers accommodations. For the motorist, the visit to the park is a short side trip from the Pacific and Dalles-California highways. He will find, in addition to the hotel, campsites, stores, filling stations. The park is open to travel from late June or July 1 for as long as snow does not block the roads, generally until October.
