Immense cliffs, domes, and waterfalls minute quadrangles in 1897 and laid the foundation that tower over forest, meadows, and a meandering river, Calkins' work was built on. Although Turner never creating one of the most scenic natural landscapes in completed this sizable assignment, he recognized the North America (fig. 1). In Yosemite Valley and the differing types of plutonic rocks and, for example, named adjoining uplands, the forces of erosion have exposed, the El Capitan Granite. with exceptional clarity, a highly complex assemblage of Calkins mapped the valley and adjacent areas of granitic rocks. The accompanying geologic map shows the Yosemite National Park during the period 1913 through distribution of some of the different rocks that make up 1916, at the same time that Francois Matthes was this assemblage.

YOSEMITE National Park
YOSEMITE National Park UNITED STATES RAILROAD ADMINISTRATION N AT IONAL PARK. SERIES Glacier Point, Yosemite Valley. The Half Dome in background Pa£e two An Appreciation of Yosemite NationalPark By HARRIET MONROE, Editor of "Poetry, a Magazine of Verse" Written Especially for the United Slates Railroad Administration WICE—and each time through an entire July—I have tramped with the California Sierra Club through the grandest areas of the Yosemite National Park. I have camped in the Valley, in Tuolumne Meadows, and in the lost Hetch-Hetchy—sleeping to the sound of rushing waters with mountains towering around me. I have crossed Vogelsang Pass when the mountain hemlocks were just slipping off their wet mantles of snow; I have descended the formidable Tuolumne Canyon past the third fall; and under Mount Dana I have looked down over the red rocks of Bloody Canyon to Lake Mono, lying incredibly blue among the pink and lilac craters of dead volcanoes. My memories of this prismatically shattered earth are sharp in details of beauty, but all of them rise against white granite and falling waters. Never anywhere else can there be mountains so silver-white—El Capitan shouldering the sky, Cloud's Rest and the two great Domes giving back the sun, and Ritter, Lyell and Dana, fierce and jagged, guarding their inscrutable heights. And through the crevices of this gleaming granite run everywhere crystal streams—streams mad with joy that foam as they fly, and shout as they take enormous leaps over stark precipices. All kinds of falling waters—the delicate cascades of Illilouette; the wind-blown tulle of Bridal Veil; Nevada, lacy, white-fingered, taking her 600-foot leap like a step in a dance; Vernal, broad-shouldered, strong-bodied, massive, as he jumps like an athlete; and, most wonder ful of all, Yosemite, that Upper Yosemite Fall whose leap is 1,500 feet — a tall white living figure against the formidable cliff, a figure moving and breathing, tossing the spray from his eyes, shining tall and straight there like a young Greek god. -

Robert Ridgway and the 40Th Parallel Survey at Sacramento, 1867
Robert Ridgway and the 40th Parallel Survey at Sacramento, 1867 John H. Harris, 12806 Lancaster Road, Oakdale, CA 95361. [email protected] In the summer of 1867, the 40th Parallel Survey party began what would become a five-year journey across the Great Basin of North America. The survey, established by an act of Congress on March 2, 1867, had the task of exploring the landscape and geological resources along the potential route of the transcontinental railroad. The concept for the survey was developed by Clarence King, who had been part of the Josiah Whitney’s California Geological Survey. Under King’s direction, particular attention was paid to geology and mineral resources, but a tremendous amount of data was collected on all natural resources, including birds. The survey’s ornithologist was Robert Ridgway, then 17 years of age and embarking on his first professional employment. Ridgway would go on to become one of America’s most eminent ornithologists (Lewis 2012). The survey had the ambitious goal of studying a roughly 100 mile (160 km)-wide swath along the 40th parallel of latitude from the Sierra Nevada to the Rockies, roughly along the proposed route of the Union Pacific and Central Pacific Railroads. King’s survey party was comprised of 15-20 members, including geologists, surveyors, support personnel such as teamsters and cooks, as well as Ridgway and the botanist William Bailey. The party was joined by a company of 20 U.S. Cavalry. The survey party sailed to San Francisco and then set up a camp in the Sacramento area, spending from June 6 to July 4, 1867 there while preparing for the arduous journey ahead. -
