elrojo14 asked me to post a link to the State benchmark datasheets. You can download the entire state information, but the files are huge! And, once you get them, they are almost unreadable.
To make this file readable, there is a program that converts the NGS data to GPX data called, creatively, NGS»GPX. This makes the file readable in a number of ways: it allows programs like Google Earth to show the BM on a map with the description information, and it puts the gpx file in a readable format in a text editor (like Notepad). However, it makes the file much bigger in size.
The only way I've seen to make this work offline is to get the information into Google Earth, then select the BM that I want to visit and create a new Google Earth file with just those in it. The reason to pair it down is because the computer has a tough enough time handling the gpx file, let alone a phone. Once I have that Google Earth file, email the file to myself so I have the file stored on my phone. Then open the file in the mobile Google Earth app. All of this so I can have a paperless BM hunt.
