I'm entertaining guesses on what made these holes in basalt.

Re: Petrified Wisconsin Swiss Cheese??
These were made by our neanderthal ancestors.
The neanderthal camera club (Wisconsin chapter) was out one day on a dinosaur shoot. The Nikon users were so frustrated that they couldn't produce the same quality of images that their Canon using colleagues were making, that they smashed their cameras onto, what was then, the soft mud and created these holes. Then they went off to the camera store and bought Canons!
Or maybe there's some other explanation!Last edited by Donald; 18th July 2013 at 07:35 AM.

Donald, what was the Wisconsin chapter doing in Minnesota? Also you have it backwards: the Canon owners were frustrated that THEY could not produce as good as pics as the Nikon users.

More seriously, I believe that sink holes can occur in basalt when lava tubes collapse, which looks like what might have happened here (any geologists out there)

No Donald, it happened because the Canon owners spent a long time failing to prove that Canon cameras are the equal of Nikon cameras and they forgot to stop digging! Originally Posted by Donald

Love it! Originally Posted by John 2

Donald, follow your instincts! When one of the several ice ages passed, the glacial river passed through and formed eddies. Sand and gravel bored out the potholes in the basalt, much like a hydraulic drill. The river valley itself formed in a crack caused by an ancient earthquake.

....and on the eight day, the Nikon God removed the ground from beneath the feet of any Canon owners as penance and they fell to the centre of the earth, to be consumed in fire and brimstone.
