Wilmington-based Cape Fear Riverwood Corp. recovers centuries-old logs from the bottom of the Cape Fear River. Loggers from the late 1700s to early 1900s floated them downriver. Many that sank along the route are rare old-growth cypress, loblolly pine and longleaf pine between 300 and 700 years old. Once cut, the wood is used in flooring, furniture, and house building. The old growth wood is more desirable because it is stronger, yet softer on the feet when used as flooring, and has more interesting growth patterns. The seven-year-old company was purchased sixteen months ago by a group of investors.
