This past week, there’s been a beautiful sight along the stretch of the Fort Valley Road that goes past the Blue Hole section of Passage Creek.
Ice has been forming beautiful forms as groundwater seeps out along bedding planes in the Massanutten Sandstone (a Silurian-aged quartz arenite, folded during late Paleozoic Alleghanian deformation). At this site, the bedding dips moderately to the south. This is close to the axis of the Massanutten Synclinorium. Here’s a look at the bedding highlighted:
And here are a few shots showing the variety of icy forms at the site:
Finally, here’s another high-speed commuting video, which features some regular-speed footage of the ice seep site, starting at 1:38. Enjoy!
