[Az-Geocaching] Bench Mark or not?

[Robert & Linda Smith]

While doing some maintenance on a cache for a friend of mine I found 
this mark that I thought was a "Bench Mark",  I guess not. It was placed 
by the U.S. Dept. of the Interior - Bur. of Land Management.  The 
marking on it seems to be "T14NR2W" below that is "1/4" and below that 
is S8 | S9 so I guess I have NOT found a bench mark.  Oh well...
