Bryant – the need for a great urban park in New York City (Manhattan island).
Thoreau – he proposed protection for acres of forests in every township.
Olmsted – proposed in 1862 the reservation of the entire Yosemite Valley and Mariposa Big Trees.
Bierstadt – in 1864, he painted a landscape depicting the floor of the valley.
Muir – wrote about the place as a temple of GodÕs creation with the command to steward the park.

The schism in the movement to protect the environment fractures into:
Preservationists
Parks protection, [National Forests, Parks]
Wildlife refuge,s [National Wildlife Refuges]
Archaeological protection, [National Monuments]
Conservationists
Reclamation [Newlands Act & creation of the Bureau of Reclamation]
Comprehensive river management
Public power (electricity cooperatives)

Birth of ecology –as a science-- and the public planning movement (City Beautiful) as examples of the schismÕs step-children:
McGee, comprehensive watershed management as the foundation of conservation
MacKaye, scenic preservation of watershed as multi purposed land protection
Marshall, the protection of remote, inaccessible wild lands for wildlife
Leopold, the wisdom of biotic navigation
"Flows: approximately November through July, with peak flow in May. Yosemite Falls, one of the world's tallest, is actually made up of three separate falls: Upper Yosemite Fall (1,430 feet), the middle cascades (675 feet), and Lower Yosemite Fall (320 feet)."
