Geo 1095: February 17, Day 778: Grand Column

Columns form when stalactites, growing down from the ceiling, meet and join with stalagmites growing up from the ground. This so-called Grand Column (page 18) is not terribly large, which is what the prefix "grand" is usually taken to imply. However it has very nice form, and it's right on the trail, so not only can you get a good close look at, but you can take another photo with Dana for scale...

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.)
