This crop from my 1200dpi scan of the Portland Mill on eastern slope of Battle Mountain is an enhanced, twisted - as in upper right corner stretched out to square off the walls better – is shared as a fully 1200dpi scan coming in at 5600 pixels wide.
   The railroad line seen almost the bottom of the image, is the Short Line Portland/Ajax Mines branch, and at one time this was crossed by the original High Line Electric grade down to Victor, the crossing was behind the house seen, one can still make out the grade to the right of the house, and partly to the left as a fill partly hiding in bushes lowering itself faster on the hill then where the tracks now run. Sadly though, this copy of this scene also suffers a little from blurring of the side.Portland Mill on Battle Mountain [Faded]
