While much of the physical evidence of the G&P has disappeared since the railroad's abandonment, numerous traces of the route still remain visible in the 21st Century. The line's eastern terminus at Armstead is now beneath the waters of Clark Canyon Reservoir. Elsewhere, though, most of the railroad's grade in Montana remains readily visible, as does the former alignment over Bannock Pass. Less of the old G&P grade between Leadore and Salmon is evident today, due to agricultural and highway development, as the highway is on the G&P right of way for most of the way from Leadore to Salmon. The Bannock Pass tunnel remains visible, although the bore has partially collapsed. Gilmore has long been a ghost town.
