On the txtopo11 are NGS Benchmarks Searchable as POIs?

[jherber]

As a newbie to mapping I have a question I cannot find by searching the Forum.

I saw on the list of information on the txtopo11 map the following:
       POI's - USGS GNIS (2011 Feb) - enhanced. NGS benchmarks

Does this mean the benchmarks are listed as POIs which are searchable using a Garmin Oregon 450? Or are they just icons on the map display only?

Thanks, Joe
