This pre-1900 railroad map of the Iron Mountain & Southern RR shows the Gads Hill location (left side of the large R). The James/Younger gang passed through Chalk Bluff Arkansas located at the extreme upper right corner of Arkansas (not on modern maps). The most logical route north for them would have been on dry land between the Black River on the left and the St. Francis River on the right. The 1870 census indicates my great, great grandparents were living near Altha, Stoddard County. This is the only map that I have found that shows Altha.
