Block of the first lava dome, deposited in Drift River valley 5 km downstream from Redoubt Volcano. Redoubt Volcano, Alaska. 1989-1990. Album caption: Block of the first lava dome, deposited in Drift River valley 5 km downstream from Redoubt Volcano. The block was transported downstream by a debris flow caused by an explosive episode on January 8, 1990. When measured 6 days later, the temperature of the rock was still 145 "C.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
