This Massive Wyoming Cave Is So Expansive It Spans Two States

In this day and age when everybody has pretty much seen and heard it all, it’s impressive when something as basic and natural as the Wyoming wilderness can retain its secrets — especially when the things that it’s hiding are enormous. Take the case of Horsethief Cave in the Bighorn Mountains. You would never know that it’s there unless you’re looking for it and know where to find it. Yet, it’s a massive cave so immense that it extends into two states and is actually part of the largest cave system in Wyoming and Montana.
