On an extended visit to the West in the spring of 1903, President Roosevelt sought the company of naturalists John Burroughs and John Muir. With Burroughs, Roosevelt camped in Yellowstone Park for two weeks, and with Muir he explored the wonders of the Yosemite Valley and had his picture taken in front of a giant sequoia tree in the Mariposa Grove. Roosevelt's visit was an opportunity for Muir to be able to impress upon the President the need for immediate preservation measures, especially for the giant forests. In 1908, Roosevelt paid tribute to Muir by designating Muir Woods, a redwood forest north of San Francisco, a national monument.
