Being very new at this, is there any database where I can look up an area or view a map with the benchmarks shown? THEN looking up coordinates as opposed to the search feature on this site. Ex: I recently found a marker near the base of catfish fire tower in blairstown, nj. I'm sure its listed if i were to enter zip code, but is there anyplace that would list them or show them on a map?? One of the best sites i've found in a loooog time!!
