Is it cooler, farther down?

Subsurface temperature in a particular area is the mean yearly surface air
temperature (e.g. in central wisconsin, cave temperatures are around
52F.)

One would assume that the mean temperature is much greater in
southern Nevada.

The further down one goes, the warmer it gets :-)
