Gearing up to move forward with building a sulfur spring analog in the lab.  I realized I have forgotten a lot of what we covered in geochemistry for equilibrium constants, dissolution in solutions, solubility, and the like.  Going back and reading "Thermodynamics of Natural Systems" to try to build up a sound idea of the theory once again.  I hope I can get this thing moving forward before too long.

Here's a fun link.  Syd Mead is the guy who developed the futuristic scenery for films such as Blade Runner, Tron, Alien, and Minority Report.  His art is fantastic!  Check his site out:
