Item is a copy of a map created by the Pacific Great Eastern Railway, showing the right-of-way of their rail line along part of the lower Cheakamus River valley from north of the Cheekye River and a portion of the lower Squamish River. The map also shows the right-of-way through District Lots 1817, 2421 and 2565. The map was most likely acquired by the City Engineer's Office as a reference map for the hydro electric surveys of the Squamish and Cheakamus river systems.
