Hello all something that has always grabbed my curiosity is a "washed" away boundary marker from the Republic of Texas days.
International Boundary Marker - Historical Sites & Places of Interest - About Logansport - Town of Logansport Louisiana
Important part...
"As a result of erosion, the first granite marker on the Sabine fell into the river long ago, but a second granite marker on the northward path of the surveyors replaced it to mark the North-South Meridian. This is the only known marker to remain, and it is believed to be the only original International Boundary within the contiguous U.S. Today, the border between Texas and Louisiana follows the Sabine River to the 32nd Parallel, where it connects to the boundary established by Hunt and Forsyth. The Texas Historical Foundation purchased this site to provide public access to the early boundary marker."
I think it would be a neat and historical find. I do not think it has even caught any ones real attention either. I think over time it was just accepted that it was missing. A few things that interest me in the hunt is the fact that with old maps and current technology you could probably have a good chance to get close at the start. Play around with some erosion figures and could just stumble upon the marker in the middle of the river. It is a huge marker, nothing metallic about it though. Probably buried in sand, but would not travel far down the river due to the weight. Sunken no doubt, but there are a lot of hard stratigraphic beds in the area. Do not think it would go too deep. Anyway just something that has always interested me! Thought I would share.
