Map 40- shows horizontal railroad on dirt and a rat: I thought the rat wouldve been the give-away since it was there; I circled the entire railroad and there are no rats... (had to go around a second time to search for the exact dirt pattern)
Map 47 (I think)- or whichever map location is shown in the attachment: this one was really hard. The corresponding map showed bushes, but the bushes were removed from this cliff at some point.
