Project E.L.F. – The history of communicating with submarines underwater

“Nestled deep in the Chequamegon-Nicolet National Forest in Northwest Wisconsin is the small town of Clam Lake. Clam Lake is best known for the excellent hunting and fishing in the area, and of course the herd of elk that roam the countryside. But the elk population is more of a side effect of what I’m going to talk about today. At one time this area was home to a military base and in fact, world war three could have been signaled from its location. I’m talking about Project ELF, the Navy’s program to send messages to submarines deep under water. Let’s explore Project ELF, a cold war relic that still has an impact today.”
