As a general rule, it's 58 degrees fahrenheit from within a few hundred feet of a cave's mouth to about half a mile down. Below that point, the pressure of the air and the rock above it causes an increase in temperature. Once you get to about a mile down, it can easily maintain a temperature close to 100 degrees.

It depends on the latitude, climate, and soil type. Near the equator, the temperature is stable within a foot or less under the surface in forested areas and within several feet in desert regions. At the polar regions, the temperature of the permafrost remains more or less constant year round. Permafrost may thaw only several inches from the surface in some places, or may thaw completely in others, so the depth varies. In temperate regions, temperatures become stable anywhere from 4-20 feet underground, depending on how cold the winters get.

Not very deep; local caverns in this area are about 30 feet deep or so and have an even year-around temperature.
