cross the North Platte River at Park Range Ranch in North Park, Colorado. The Park Range is a spectacular series of Rocky Mountain peaks overlooking the "park." This vast area, up dirt roads out of Walden, Colorado, in Jackson County, one of the the least-populated counties in America, is a somewhat like a beautiful national park minus tourists. The Park Range Ranch includes two operations: a working cattle ranch and a private guest ranch, called "Fort Boettcher," for friends of the owner. Photo by Carol Highsmith.
