Same thing here in Nevada. I used to hunt chukar with my dad at N-word Creek, which was later changed to Negro Creek. Haven’t looked lately to see what it’s been changed to now, if at all. At least it wasn’t as bad as M-fer Mountain down in Central NV near Tonopah.
We have a lake in sullivan county PA that was called niger lake on the map.I dont know if it has been changed yet but it propably has. I have to check on that.
