Smith Cemetery, Clay County, Kentucky, US
Notes:
Death certificate states place of burial as Smith Cemetery and in the space on the form for undertaker it states "buried by friends". Guessing they wouldn't have buried him far from his home, so a possible location is Sextons Creek, Clay County, Kentucky

This might be it and it looks like it's by a creek/stream
