The resources of the project are strongly associated with the early development of electricity in the southern Oregon and northern California region and played a significant role in the area’s economy both directly, as a part of a regionally-significant, locally-owned and operated, private utility, and indirectly, through the role that increased electrical capacity played in the expansion of the timber, agriculture, and recreation industries during the first six decades of the 20th century. The Klamath Hydroelectric Project is considered regionally significant and eligible for listing in the National Register of Historic Places under Criterion “A” for its association with the industrial and economic development of southern Oregon and northern California.

Peak on skyline is 8,929 feet (2,722 meters) Mount Scott, an ~420 thousand years before present (ka) dacite stratovolcano considered to be part of Mount Mazama, the volcano that collapsed during the caldera-forming eruption ~7,700 years ago. The caldera walls in this view expose Mazama lava flows and fragmental deposits from as old as ~400 ka at Phantom Cone, adjacent to tiny Phantom Ship island, to as young as ~27 ka at Redcloud Cliff, the V-shaped face at the top of the wall left of center. The beheaded glacial valley of Kerr Notch, the low point on the caldera rim, is seen between Phantom Ship and Mount Scott. Photograph by Carly McLanahan. Cover (bottom photo): Newberry Volcano, Oregon, is the largest volcano in the Cascades volcanic arc. This north-facing view taken from the volcano’s peak, Paulina Peak (elevation 7,984 feet), encompasses much of the volcano’s 4-by-5-milewide central caldera, a volcanic depression formed in a powerful explosive eruption about 75,000 years ago. The caldera’s two lakes, Paulina Lake (left) and the slightly higher East Lake (right), are fed in part by active hot springs heated by molten rock (magma) deep beneath the caldera. The Central Pumice Cone sits between the lakes.

HlLLMAN STEEL POINTS (JUNIOR) VOL. 1 AUGUST, 1925 No. 2 CRATER LAKE Crater Lake National Park is located on the summit of the Cascade range of mountains, in Southern Oregon, and contains 249 square miles, one-fifth the size of Rhode Island. It was created by act of congress, approved May 22, 1902, and within it is one of the world's greatest natural curiosities. Originally a mountain 15,000 feet high, covered with perpetual snow and great glaciers, it emitted a stream of boiling lava that filled vast canyons. The world was unsettled in those days and the elements were at war. Finally a time came when this immense mountain tottered and fell within itself, 17 cubic miles of matter disappearing within it, leaving a cauldron five and one-half miles in diameter, a seething mass of hoiling lava, probably 5,000 feet deep, as all that part of the mountain above 7,000 feet elevation disappeared. Ages came and went as the days, and this boiling mass began to cool. Slowly, hut surely. Snows and rains descended, evaporated and disappeared. Finally a little pocket in the cooling lava filled with water, but the warm base and sun dried it up. Bye and bye others appeared and were a little larger. The cooling process continued. At last little pools continued over Summer and Winter and increased in size, then they joined and spread over more lava.

  • View the Klamath Summary Report
    SPECIAL SUPPLEMENT — KLAMATH BASIN GENERAL STREAM ADJUDICATION From the top of a fault formed ridge overlooking the expansive Upper Klamath Lake, the rest of the world seems to fall away. Unbroken blue skies and dry, thin air stretches the horizon impossibly far. To the east, parched buttes roll through deep, green farm-filled valleys. To the west, only the rugged, snow- capped Cascades can rein in the view. The feeling of freedom that defines the American West is alive in this place. Prepared by the Oregon Water Resources Department — October 1999 he Klamath Basin defies the soggy Northwest stereotype. The Cascade TMountains steal the moisture from eastward winds, transforming the damp, green Oregon known to most of the country. Away from the mountainsides, Lodge Pole and Ponderosa Pines supplant the water-dependent firs. The moss-covered logs and thick tangles of plants of the western forests are gone. In their place, reddish- black volcanic rocks speckle hillsides adorned with dusty sage. Sandy pumice soils are exposed to the wind and sun by the sparse ground cover. Everything seems to crack and crumble underfoot. Despite these desert-like conditions, an oasis of lakes, rivers, and marshes teams with wildlife. The remnants of a huge prehistoric lake once provided a cache of resources that allowed the Basin’s earliest human inhabitants to thrive in an otherwise formi- dable environment. Much time has passed and cultures have changed, but the reliance on these same resources has not. For more than 100 years, settlers, homesteaders, and their descendants have defied the desert by transforming vast lakes and marshes into farms and pasture–creating a heritage in the process.

No place else on earth Place Else On Earth combines such a deep, pure lake with sheer surrounding cliffs and a violent volcanic past.

  • USGS Scientific Investigations Map 2832, Pamphlet
    Geologic Map of Mount Mazama and Crater Lake Caldera, Oregon By Charles R. Bacon Pamphlet to accompany Scientific Investigations Map 2832 View from the south-southwest rim of Crater Lake caldera showing the caldera wall from Hillman Peak on the west to Cleetwood Cove on the north. Crater Lake fills half of the 8- by 10-km-diameter caldera formed during the climactic eruption of Mount Mazama volcano approximately 7,700 years ago. Volcanic rocks exposed in the caldera walls and on the flanks record over 400,000 years of eruptive history. The exposed cinder cone and andesite lava flows on Wizard Island represent only 2 percent of the total volume of postcaldera volcanic rock that is largely covered by Crater Lake. Beyond Wizard Island, the great cliff of Llao Rock, rhyodacite lava emplaced 100–200 years before the caldera-forming eruption, dominates the northwest caldera wall where andesite lava flows at the lakeshore are approximately 150,000 years old. 2008 U.S. Department of the Interior U.S. Geological Survey This page intentionally left blank.

The new members to Historic Hotels of America are located in the following National Parks: Grand Canyon National Park, Crater Lake National Park, Yellowstone National Park, Zion National Park, and Death Valley National Park. Historic Hotels of America welcomes Phantom Ranch, Bright Angel Lodge and Cabins, and El Tovar from Grand Canyon National Park. Bright Angel Lodge was listed in the National Register of Historic Places in 1982, features great panoramic vistas, and is known to be the hub of the South Rim. El Tovar was listed in the National Register of Historic Places in 1974 and on May 28, 1987, El Tovar was designated by the U.S. Secretary of the Interior as a National Historic Landmark. Phantom Ranch, built in 1922, on the north side of the Colorado River is the only lodging facility located below the canyon rim. Zion Lodge in Zion National Park is also a newly appointed member of Historic Hotels of America. Zion Lodge was listed in the National Register of Historic Places in 1987.
