Hi the Midland trail in Nevada was part a coast to coast highway that follow the Lincoln Highway from Salt Lake City to Ely, Nv and then went south west to Big Pine California Via Tonopah, Nv. Layed out by A L Westgaurd before the Lincoln Highway and is perhaps the only road, that Carl Fisher was on in Nevada.
There is a 1916 Guide published by The Midland Trail log Book Company. This guide included West Virginia and St Louis Missouri. This guidle was unusal as it list both westbound and east bound. Many other guides like the Lincoln Highway list only the east to west.
