Yosemite National Park: Past and Present

I-Ting Chiang lives in the San Francisco Bay area. He has photographed Yosemite National Park many times since relocating to the United States from Taiwan in 2002. Suzanne Silverthorn, of Vail, Colorado, has transformed her interest in the history of the national parks into an extensive postcard collection dating from the early 1900s to the 1960s.
