Geo 1095: February 8, Day 769: Groundwater, Underground

I was planning on skipping this photo of Oregon Caves' "River Styx," but I realized it's a sight seen only under unusual circumstances, such as in a cave. One doesn't often actually see groundwater that is still technically "groundwater." We see springs, and streams largely sourced with groundwater, by the time we see it, it's normally surface water. So there's a lesson in this: if you want to actually see groundwater, you have to go underground. It's a hipster thing... you wouldn't get it. (BTW, the white swath along the left side is flash glare, reflected from the walkway.)

Photo unmodified. May 9, 2013. FlashEarth Location. (Since we're underground, I have only a vague idea where this is with respect to the surface.)
