> but do you think it is true that it comes from snow melt above SB 23? Is there any snow up there to melt any more? I always assumed that it came from deep down under since the water still flows long after the snow above it has melted.

Good point, Brent N. I don't think there is any snow left higher up, so the water has to be flowing from an aquifer that must have more of a long-term storage capacity, and so probably results from snow melt from a wider area, too. That being the case, the water is most likely filtered through lots of underground layers, so should be about as pure as it can be.

It would be interesting to see a comparison analysis of this water and the Crystal Geyser water that is bottled in Olancha along the Hwy 395.
