Hi All. It appears that the uplift at Three Sisters volcanos is still going on. However there is some new data concerning spring water. Analyses of spring-water samples collected in late summer 2001 are similar to those from earlier surveys but isotopic studies of carbon and helium in the most recent samples, which were not done previously, suggest a magmatic source.

The most recent radar data confirm that uplift continued through the summer of 2001, and daily data from the continuous GPS station installed in May 2001 show that uplift continues to the present. Meanwhile, seismicity in the area has remained at a low, background level. Take Care…Don in creepy town
