The
only high tide access for a shallop on“The Island” is
along a strip of high ground that became a road by 1865. So if your access is through Monquin, it is natural that you always draw Monquin creek instead of Pampatike when you draw “The Island”
There also is a possibility that the
Pampatike creek branch (blind
5) was clear enough for canoes but not for a shallop.
