Thanks for the nice comments regarding this hobby.
The Washington DC tsunami was based on the premise that if a 5 KM asteroid hits the Atlantic Ocean it would produce a tidal wave 1 mile high. I don't know if I got the scale exact but a 1/4 mile one way or another wouldn't make much difference.
Living in the DC area one finds huge deposits and chunks of shocked white, pink or orangish quartz that was produced from an asteroid impact that struck nearby forming the Chesapeak Bay. Also because of the impact many layers were blown away so very old dinosaur fossils abound here.

As for picking up the buzz from like minds out of the ether, I think we all have that experience. Unexplained insight is probably more ubiquitous than we are willing to admit. All that differs are the "like minds". For example Brittany Spears will have different predictive insights than Steven Hawkings.

If I upload 15 of my images on my website everyday, I will catch up on this updating project by summer. I wish I could maintain 2 obsessive hobbies at the same time. I have all but completely ignored music projects.
