His theory about such a large den being on the very edge of the range is perhaps that as snakes keep spreading northward there is a certain limit to where their needs aren't met. Thus, the majority collect at the fringe, and the minority that continue to move north die. The fact that this is a perfect, and huge den, allows the collection to comfortably house many snakes.

I hope to attend a spring count, if I do, perhaps I'll have some pictures to share
