The CCC was the Civilian Conservation Corps and was set up during the depression for young men, mostly unskilled to get them off the streets and give them something constructive to do. My Dad spent time ina CCC camp in Colorado in the 1930's as a teenager, mostly clearing brush and planting trees, building parks and minor construction jobs such as building cabins for wildlife conservation or whatever it was called back then. The got room and board and very minimum wages. The WPA on the other hand was mostly older skilled workers who could not find work that took on major construction such as roads, swimming pools, government buildings, bridges, sidewalks, etc. Many WPA projects are still evident especially in urban areas. They built many of the old stone National Guard and Army Reserve buildings. They usually will have a marker of some sort designating same. My leased hunting area is bounded on one side by an old abandoned WPA road that was built from a section line going back to a gravel quary. The bridges have been dinamited or washed out all along the road and access is by foot or 4 wheeled ATV's. The road was built back in the late 20's and 30's and they used wagons and mules. I found an old iron wagon wheel hoop and a muleshoe on the road when I first got my detactor.
