- The Georgia-Pacific Paper Mill, with its broad columns of steam slowly billowing skyward, is the dominant feature of the small city of Camas. The town’s industrial history goes back a long way - to the first sawmills of the 1850s. In 1884, Henry Pittock’s LaCamas Colony Company used Chinese laborers to construct a 7,000-foot ditch that would carry water from Round Lake to its new mill on the site of the current Georgia-Pacific operation. This aqueduct is still in operation and serving its original purpose; indeed, hikers have to chance to walk much of the ditch as well as connect to its source at Mill Pond in Lacamas Park, where they can also make use of a much wider network of trails.
