A friend of mine found an old antique gun and it is missing a piece. The general area it was found in has been flooded several times since the find (95 and 04 for sure and maybe some other years too). We would like to be able to compare where the creeks run today in comparison to when the gun was found in the mid 80's as it was found near but not next to a creek.
It may not even be a topo map we are looking for, but it may help.
Thanks for all your suggestions and if you have more to share, please do.
