Garmin map 62S.
I was scrolling a street map using NC topo map downloaded from here. I found a round icon and when I hovered, it read BM 1754.400 . When I put the coordinates into a geocache benchmark search it goes to benchmark FB3997. The question is, is there a USGS page that would use the 'BM' number? I've found nothing by 'googling'.
