The most memorable feature is not natural at all but a man-made rock bridge that was built by quarry workers, likely during the 1950s, to save time moving men and machinery from one side of the pit to the other. Huge blocks (unsuitable for polishing) were piled up jigsaw-fashion to form a wall with an entrance, eight-feet tall, to pass through.

Gravel roads leading through the quarry areas are lined with crushed rock, with little pockets of rock forming inlets along the road meant to capture runoff. Schwab said that Biesanz works hard to control that runoff, routing it to the rock edges of the roadway which act as filters and prevent significant erosion from the roadway and hillsides.
