With Brain & Pinky, Eikenhofjes and Xizat I travelled 11 days through the USA to find some very old caches. On our 5th day we found some caches in Seattle and visited Head Quarters.
The Wedgwood Erratic was a boulder that was left by the Vashon glacier 11,000 years ago. We measured the rock and everyone took a picture. What an interesting place!
Thanks and cheers!
