Santa Fe NM 23 June 2019: Santa Fe River Park, with the Santa Fe River and CCC-built stonework and landscaping. "The Santa Fe River Park includes flagstone walkways, a stone-lined acequia channel, picnic tables, limestone-block walls lining the banks and thousands of trees. The park was developed in several phases, at undetermined costs, by the Civilian Conservation Corps between 1935 and 1940. David Kammer, an Albuquerque historian, said Stephen DeBoer, a landscape architect who designed Denver's park system, originally envisioned the park stretching some 20 miles, all the way to La Bajada. The New Deal made money available for state parks, but initially New Mexico had no state parks, so a system had to be created, beginning with the Santa Fe River Park and Hyde Memorial State Park. The first major task was straightening the river's meandering path through downtown Santa Fe."[1]
