Map depicting all surveyed boundary lines and all survey monuments within a 600 metre radius of Canada's four corners.
Included on the map are two distances:

ground distance from Monument 157 to 102nd meridian west
ground distance from Monument 157 to 60th parallel northThe two distances are calculated in UTM space and then scaled with the appropriate combined scale factor.

The two distances only apply to Monument 157 and not to the boundary lines or other monuments.  To be clear, the boundary lines are not parallel to the meridians or parallels even though they may appear to be parallel over short distances.
