As is the case with any large scale model railroad, a great deal of selective compression is called for in order to make your chosen line fit the limitations of your yard and your budget. These two maps were taken from a recent study which re-mapped the old KMR . Much of the line is gone, not just because of natural erosion but mainly due to extensive dredging and hydraulic mining activities which have significantly altered the landscape since the railroad was abandoned in 1913.
This is especially the case for the area downstream from Grand Forks, which itself is non-existent.
