No photograph or series of photographs, no paintings ever prepare a visitor so that he is not taken by surprise, for could the scenes be faithfully represented the visitor is affected not only by that upon which his eye is at any moment fixed, but by all that with which on every side it is associated, and of which it is seen only as an inherent part. For the same reason no description, no measurements, no comparisons are of much value. Indeed the attention called by these to points in some definite way remarkable, by fixing the mind on mere matters of wonder or curiosity prevent the true and far more extraordinary character of the scenery from being appreciated.
– Frederick Law Olmsted, A Preliminary Report on Yosemite and the Mariposa Grove, 1865
On June 30, 1864, President Abraham Lincoln signed a bill granting Yosemite Valley and the Mariposa Grove of Giant Sequoias to the state of California. This was the first time that a tract of land was set aside for the enjoyment of the people simply for its breathtaking scenery and the uniqueness of its natural features. This act and the two Supreme Court decisions over the next sixteen years that would uphold it and clarify its provisions established the legal precedent from which descended all federal and state parks in the United States as well as the export of the concept across the globe. Yellowstone became the first National Park eight years later only because the astonishing geothermal features of the Yellowstone River watershed were located in a territory and there wasn’t a state to grant the land to. Although the Yellowstone precedent ensured the enduring federal protection of land, Yosemite is the birthplace of the National Parks.
