Sounds like to me that the deer are pressured there. I draw this conclusion from no noticeable trails coming out and crossing the line. Deer here at least will scatter where crossing openings if they have been pressured very much in the past. I would follow the line while in the woods roughly 20 to 30 yards. This should allow you to find the trails they use before crossing the line. Also almost due south of your marker/cabin is a place the looks like saplings or small shrubs growing across the line?? If that is the case deer will try crossing there where they can receive some cover from the opening.

Now I am looking southeast of your marker/cabin and it looks like a skidder trail running towards a field? If so they make great trails to watch for deer traveling. Skidder trails or logging trails make great deer trails if you can spend the time setting and watching them.
Good Luck on your scouting.
