My daughter and I were trying to come up with a name about the same time there was a Heritage Canada commercial on T.V. In it some Inuit were travelling by canoe with a non native. When they got to shore, the Inuit people made and Inukshuk and the man asked why do they do this? Their response was " So that people will know we were here."
So by signing the logbook "Inukshuk"ers, we are letting people know we were there!!!
