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. </blockquote>
<p>I was writing an answer about this but David did it faster.</p>
<p>There is more than one confusion here. As David writes, the OP
was referring to latitude bands, N vs S, that have no relation to
the hemispheres. Just an unfortunate coincidence.</p>
<p>Zone 13N (not 13 North, but band N) has a limit on the Equator
(0° - 8°N). The coordinates shown are on 13S (32°N - 40°N).<br>
