We were in the area of Ricketts Glen State Park for the Red Rock and Rolls event cache (geocachers' picnic), and had planned to arrive early in order to find a cache or two before meeting everybody else at the pavilion. Not far from the starting point for Mike(Bonanza)Burnside's intriguing Downtown Ricketts cache, I spotted the concrete bridge and thought "That would be a good spot for a benchmark." What do you know, there was one right there just a few feet from where I stood, beneath plenty of dirt and gravel, but obvious enough. I knew that LZ0099 was somewhere nearby, but as soon as I uncovered this mark I realized this wasn't it. Still, it was a cool bonus find! It's located on top of the southeast wingwall of a bridge on Route 487 over Mehoopany Creek, below the level of the road. The disk has no stamping, and I can't find a reference to it in any database. It's a Pennsylvania Department of Highways disk like many others that do appear in the NGS database.
