Greywacke Arch, the Real Story
Attention!
Danger! Misty Extracto Zone! Beware of Greywake Arch!
Officially this arch is named for the variety of Hudson Valley sandstone with which it is built, but this is a completely uninformed reading of the term Wacke! Look at the etymology... Wacke noun
1. a kind of rock, boulder This is as far as the official definition goes. However, Wacke is (alternative spelling of)
2. Wacky.
And, Wacke is from Old High German waggo or wacko, probably cognate with Old High German wegan "to move" !
The Terrifying Truth is that we have a Grey Wacko Arch that causes things to not only Move but to slowly Disappear into one of the few remaining Misty Extracto Zones!
Thank goodness we discovered it in time.
