Crater Lake

To encourage domestic tourism and to promote America's national parks, a series of ten stamps was issued on various dates from July 16 to October 8, 1934. In denominations of 1- to 10-cents, the stamps depict scenes from the national parks in various colors.

The 6-cent dark blue National Parks stamp issued September 5, 1934, pictures Crater Lake, a six mile wide body of water occupying the caldera of an ancient volcano. The color of the stamp suggests the deep blue waters of the lake, whose maximum depth is 1,932 feet. Crater Lake National Park was established in Oregon in 1902.
