What exactly are sand farms and sand counties?

Sand Counties are another area of Wisconsin that the narrator has a deep love for. The social planners saw beauty in the Sand Counties too, but for building reasons only. The narrator bought a sand farm in the 1930's as did many people during this time. The narrator finds that the sand farms aren't as poor as people originally led on, because there are a myriad of plant species that grow in the sand. In April, the pasque-flowers bloom on every gravelly ridge, and the sandwort comes out with its white bloom on the poorest of hilltops just before the lupine lets out its blue blooms.
