This is actually 2 different pictures. You can see the difference in the railings that are remaining on the steps. They say a picture is worth a thousand words, so I'll give you a little less words.
These pictures were taken across the road from an abandoned Silver Mine (yes, the one I show all the time with the Bantorus MC clubhouse as the mine, which you can see here). A hundred years ago, miners built houses up on the mountain to be close to work. Those houses are long gone, though you can see some concrete left from the pillar foundation.
While the miners worked long hours, day after day, their women were bored. Since they couldn't go to town and hang out with all the prostitutes, they decided to build rock walls and steps to make it easier to walk to each other's houses and provide a place they could plant flowers. You had to be a strong woman to be a miner's wife, and I think that shows in the rock wall that remains standing after all these years.
