Spray Geyser has been a consistently active geyser with a dynamic and fluctuating microbial population that includes a variably impressive red layer community. We have surveyed these springs annually since 1998. We did not begin sampling until 1999 given the lack of obvious mat in 1998 (and concerns about approaching this geyser). At this writing (9/01), the community appears to be vanishing yet again and we are curious to see what happens next year. Access is via Fairy Falls and a public trail reaches the feature after 3-4 miles. This geyser is probably the most dangerous in our study as it seems to change its mind often - whether in terms of timing, source, or volume.
