Actually, that's pretty close to me. It's in Los Alamos, NM. (I'm
about 75 miles WNW).<br>

There is some confusion about the naming of UTM zones. According to
<a moz-do-not-send="true"
href="https://en.wikipedia.org/wiki/Universal_Transverse_Mercator_coordinate_system#UTM_zone">Wikipedia</a>,
the latitude bands are not part of the UTM description, but rather
from the MGRS. Nonetheless, UTM grid references are sometimes given,
creating the ambiguity between 13S meaning latitude band S vs.
meaning a UTM coordinate south of the equator. In the case of the
coordinates given here, 13N means zone 13 north, and is not a
latitude band reference. <br>
