Kevin,
Thank you for posting the URL for the seiche information. At the Forest Park Swimming Pool in Everett over a foot of water was sloshed out of the pool by the oscillations. People in the pool and the lifeguards were all freaked by the rather large waves that were set up by the otherwise imperceptible resonant motion. I and most of the people I have talked to about it were unaware of a phenomenon known as a seiche. It would have been fascinating to see such an event at a frozen body of water as Stan described. BTW, the pool dimensions are 25 yards x 25 meters in an L shape with the meter length running into a diving well. I'm guessing that the simming pool was closer to a resonance condition than Stan's 16 x 42 ft pond, as the wave action was more vigorous than what Stan described (and a great description it was!).

Hi Stan,
The motion you described sounds like a lake phenomenon referred to as a seiche; such oscillations have been detected on much larger scales, in lakes and even Puget Sound. Sounds like you were fortunate to have had a model seiche right in your own backyard. I'm envious, I didn't notice any quake effects at all.
