Carlsbad Caverns National Park is located in the Guadalupe Mountains, which are part of the Permian Basin in west Texas and southeastern New Mexico. This area is located on the interior of the North American Plate, far from any active plate boundaries.

Here's why:

* Plate boundaries are where tectonic plates meet and interact. The primary types are:

* Convergent boundaries: Plates collide.

* Divergent boundaries: Plates move apart.

* Transform boundaries: Plates slide past each other.

* Carlsbad Caverns formed due to the dissolution of Permian-age limestone by acidic groundwater. This process is primarily driven by chemical weathering rather than tectonic activity.

* The Guadalupe Mountains themselves are a result of uplift and erosion due to regional tectonic forces but not directly related to a plate boundary.

Therefore, Carlsbad Caverns is not located on a plate boundary. It is in an area of the interior of a tectonic plate that experienced uplift and erosion, which eventually led to the formation of the caverns through the dissolution of limestone.
