Gushing from a glacier, rust-stained Blood Falls contains evidence that microbes have survived in prehistoric seawater deep under ice for perhaps millions of years, a new study says.

The colony of microscopic life-forms may have been trapped when Antarctica's then advancing Taylor Glacier reached into the ocean 1.5 to 4 million years ago.

What's more, the tiny organisms' feeding habits apparently give the falls their shocking color. continued...

Mars is calling, but we don't have the cab fare! Alas!

How does that look like blood? To my naive eye that looks just like acid mine drainage.

I know this article isn't about trees, but it does touch on biology and ecology. I have seen several articles about this glacier. This wasn't the most recent of those, but was a better but older description. I suppose everyone is not familiar with Acid Mine Drainage and it is fairly common to characterize any red liquid as blood. In some photos it looks more red and less orange.
