Lake Pend Oreille, northern Idaho supposedly is a place where underground water filled tunnels lead out into the Pacific. And we just had postshere about China Lake where there was an earthquake that destroyed the big underwater portal off the coast of LA. Might have been connected.

I had a dream in around 2006 in which I saw a huge city-sized, glowing blue dome underwater. The location was in the Atlantic off New Jersey. I looked that up. There is a very deep trench there. The dream was scary to me but seemed very real.
