An easy P/G just north of SR26
Gregor was a station location located at MP294.4 along the old SP&S right of way about 1 1/2 miles to the east of GZ. (Mullan Road)
The grade west to east is 0.4%. Look west toward the bridge east of Washtucna and then to the east as the route heads towards the bluffs. To me, it sure looks like the old route is a lot steeper than 0.4%!.
