Stone Columns amidst the Wilderness

As we trudged in the dense vegetatation, Tony who was leading the way suddenly shouted. He had spotted two old, worn, stone pillars. We examined the pillars but could not find markings or indication of its origins.

Nearby, I saw two stone blocks in a moss-covered concrete drain. Across the stream, I saw another pillar. Tony had also spotted yet another. I thought there were at least four pillars here.
