What is the deal with these USGS markers
I saw a bunch of these along the greenway today and never noticed them before. I understand it says “high water mark” and at first thought, “whoa!” And snapped a photo. But then I sort of kept looking around at them and realized they don’t make sense, at least not for Helene, because there is one across from Second Gear that is about waist high on me and we know that building was almost entirely submerged. For additional context, I am about 5’4” on a good day so waist high is really not that high. So, are these from a past flood - 2004? Or did someone just do their job wrong?
