The article makes it clear that Moose Boulder doesn’t exist, and that Ryan Island does exist. But, unless I missed it, there’s nothing about whether Moose Flats (the seasonal pond on Ryan Island which would contain Moose Boulder) exists. The mother and son duo joke about creating a pond by pouring water around a rock, so I’m guessing that they found no other pond on the island at the time. But that’s not a complete answer. And yes, I am purely interested in this so I know how deep the “largest lake in the largest island” chain actually goes.
