Don't know her Geoname but I think it is a book of photographs. I believe the Orrington Library has one in circulation. I know when I did the class there 2 years ago they had a great coffee table book with caches in it.

Ah yes, it was her book - here is the link for information - http://localtreasures.org/ As I remember it does have at least one Maine cache location pictured in it.
