How many limestone caves are there in the United States of America?

Update:

In terms of larger lakes in the United States, there are 123, 439 according to the EPA.

So what about caves?

Update 2:

or if that website on lakes does not work, then do a google on: "selection of sampling locations for the Survey"

    The number is in the thousands, if not hundreds of thousands. It is probably impossible to derive an accurate number because many caves may be known only to a few people, and many caves interconnect so names used for cave entrances often are later discovered to be part of the same cave system. Mammoth Cave in Kentucky is an excellent example of a cave that has now been connected and mapped to several other major caves in the area.

    A recent published paper compiled a distribution map of the caves in the United States and used 45,000 known caves in the lower 48 states. They found that one third of the counties in the US have at least one cave. Here is the paper:
