But testing the waters has proven extremely difficult as extremely thick ice and concerns about contamination have stalled any possible research. So Blood Falls, a naturally-occurring outflow of saltwater from the lake beneath Taylor’s Glacier, offers a unique opportunity to look at what might be going on under the surface of the ice
