About 70 miles north of Tampa, Florida, lies the spring-fed source of the Chassahowitzka River. Its name means “a place for the hanging pumpkins” in Seminole, and until recently it was blocked by septic tank runoff and algal overgrowth. When the Southwest Florida Water Management District decided to clean the spring up last year, it brought in SEARCH, a local cultural resources management company. Good thing, too, since amid the refuse was thousands of years of history.
