July 2009
The Rainbow Loop site was located off the popular Rainbow Loop trail in Stehekin. Natural sounds were most evident at this site, although helicopter noise was present due to fires in the area. During the site deployment, a curious bear knocked over the equipment and tore the microphone windscreen.
