The East Palisades are more strenuous (and usually less crowded). This section is a good bet for families and trail runners. You’ll follow Rottenwood Creek with multiple bridge crossings. The West Palisades section features easier hikes, with four miles of mostly paved and flat trails. The Palisades Trails are broken up into two sections, east and west. You’ll find several scenic trail systems to explore in the recreation area. Thanks in part to the Chattahoochee Riverkeeper and other organizations, residents and visitors alike can reap the benefits and continue to help make the Chattahoochee even better for all Atlantans. Located in the middle of metro Atlanta, the Chattahoochee River National Recreation Area offers excellent opportunities for kayaking, fishing, rafting, biking, hiking, bird watching and even good old tubing through numerous parks and preserves from Lake Lanier to the city itself.

Soft rot, on the other hand, is very slow acting and occurs in oxygen deprived environments such as fresh water and below grade conditions. Ground contact conditions are perfect for common wood decay because there is ambient oxygen, favorable temperature, and favorable moisture. Do the same in the northeast and the untreated 2x4 will be gone in 5-6 years. ![]() For example, stick an untreated 2x4 in the ground in the deep south and it's pretty much gone within 1-2 years. For now, I’ll simply refer to the aggressive types of wood decay as 'common wood decay,' or, as they are often referred to in construction: " dry rot." Common wood decay, which is what most of us are used to seeing, decays wood rapidly in optimal conditions. Soft rot wood decay is a common issue I encounter when working with diving, marine and geo-technical engineers. It's a slow-acting wood decay that is actually capable of causing significant damage and strength loss in wood, even though it that has been submerged in water for very long periods of time, especially untreated wood. Soft rot is a unique type of wood decay because it can survive in oxygen deprived environments, whereas its more aggressive counterparts require oxygen for growth. Upon reading this story I found it very likely that the submerged timbers were quite deteriorated, and that soft rot wood decay would be the culprit. I contacted Nichole Doub, one of the archaeologists from the Maryland Archaeological Conservation Laboratory (MAC Lab) working on preserving the wood, to discuss the process by which they preserve the wood, and to share some knowledge about how wood deteriorates in fresh water. It should come as no surprise that this story attracted my attention because of the wood science involved. According to the Baltimore Sun article, it "was a merchant ship that likely greed grain to or from the Eastern Shorte port of Vienna in the late 1700s." The timbers appear to be from a shipwreck that may extend back to the Revolutionary War era, which would make the timbers over 200 years old. Recently I read an article about a Revolutionary War-era shipwreck found submerged in the Nanticoke River near Baltimore. Divers were cleaning up debris in the river channel under the US Route 50 bridge after barge had apparently hit a system of fender piles beneath the bridge when they unexpectedly pulled up some old timbers that were not part of the barge debris. The old adage, “wood that remains completely submerged in water will not decay,” is unfortunately incorrect.
