yesterday's photo, there appears to be a correlation between tone and age in these stalactites and drapes: older ones look darker, younger ones, brighter. Also, it appears that the younger deposits are being laid down faster than in the past.
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.)
