Re: the "survey" pointed stake retrieved from Fred Nolan's swamp section - The condition makes me curious about how long the upper end was exposed to the elements before being buried. I'm guessing not very long compared to the theoretical multi-hundred year lifetime if it's dated to 1200-1500. My experience with hardwood fence posts such as hedge, oak, cypress is that they barely last a maximum of 50 years before rotting off at ground level.
