Remnants of the gold mining era. The buildings at the end of this road are associated with the old Argonaut Mine.
DON'T CROSS THE FENCE OR ENTER THESE BUILDINGS!
I recommend checking out this location around Christmas time. There's a house on this street that gets all decked out for the holidays. The muggles that live there put on a festive light show to correspond with music played on a posted radio station. Very jolly.
Happy hunting!
