Crater Lake Lodge was built in 1915 to provide overnight accommodations for visitors to Crater Lake National Park in southern Oregon, USA. The lodge is located on the southwest rim of the Crater Lake caldera overlooking the lake 1000ft below. The lodge is owned by the National Park Service, and is listed on the National Register of Historic Places.Local historyCrater Lake lies inside a caldera created 7,700 years ago when the 12000ft-high Mount Mazama collapsed following a large volcanic eruption. Over the following millennium, the caldera was filled with rain water forming today's lake. The Klamath Indians revered Crater Lake for its deep blue waters. In 1853, three gold miners found the lake. They named it Deep Blue Lake, but because the lake was so high in the Cascade Range the discovery was soon forgotten.In 1886, Captain Clarence Dutton led a United States Geological Survey party to Crater Lake. Dutton's team carried a half-ton survey boat, the Cleetwood, up the steep mountain slope and lowered it 2000ft into the lake. From the Cleetwood, Dutton used piano wire to measure the depth of the lake at 168 different points. The survey team determined the lake was 1996ft deep. This is surprisingly close to the modern sonar-based readings made in 1959 that established the lake's deepest point at 1932ft.
