I suppose the lack of silt, sand, etc., covering the formations could be influenced by their location. It could depend on the bottom composition. Parts of the Lake are all glacial till, while others are sand, others are 'muck' and others are solid rock. And there is certainly more current in some parts of the Lake, too. I've found really old stuff right on the bottom, plainly visible, and also have dug in the muck to find relatively new beer bottles.

Still, these are cool photos. Reminds me of the little rock piles I would make while snorkeling as a kid (they are still there!). More recently, I've taken to leaving markers in a line at 20-24 feet along the bottom in front of our place. They tell me when I've arrived back in front of the dock. Currently, the collection consists of an old copper kettle (with bullet holes), a wine bottle, a beer bottle, and an old rubber bucket. If you're diving along at 20 feet and come across these items, head dead East and stop in for a malted beverage.
