I am familiar with it. Saying “Mammoth” is a little like saying “Los Angeles.” The town isn’t that big - but was it by one of the back lakes? Which? How far back? Sherwin? Lost? Cloverleaf? If I could find that, I might tell you better.
I will say this: it’s October. If they want to search, they’d better move it, or they’ll have to continue next June or so.
I forget that other parts of the country actually have a winter!
