1966 Map

Here is a 1966 USGS Topo map at the mouth of Moses Coulee near the Columbia River.  Highlighted in the map is the Bonneville Power Spur (Bon Spur) which was added in 1952.  This split off from the Mansfield Branch to serve a power station (Columbia Substation as it was called) until the line was abandoned in 1985.
