There's a fire watch tower higher up the mountain, this road takes you to it. I had to check on the watch a couple weeks ago after they stopped responding to radio calls.

[ Rook takes a seat back on the tailgate, one arm slung over the side of the bed, content to sit shirtless and watch Armin for a moment. ] He said his radio malfunctioned, but I'm pretty sure he just passed out drunk 'n missed his alarm to check in. Anyway, on the way back I caught a glimpse of the view and stopped for a moment. Hadn't had a chance to come back up here until now.
