With Brain & Pinky, Eikenhofjes and Xizat I travelled 11 days through the USA to find some very old caches. On our 8th day we did a series of 'Gate caches' along Frontage Road and we drove to Provo for some Challenges.
We start the day in Twin Falls with a did-not-found and then visited this earth cache. We took pictures of the Perrine bridge over Snake River, counted the layers of lava across the canyon and viewed the statue of Ira Burton Perrine.
Thanks and cheers!
