JAWS is attached to the ship by a 100' longline. Two dredge-runs were completed, providing multiple samples from 1) mid-dome elevation (N side), and 2) top of the dome. | | Date: | August 24, 2010 | | Photographer: | Steve Anderson

Exposures of the complete Nunatak were revealed after melting of adjacent glacier ice during the 2009 eruption of Redoubt. The columnar basaltic andesite lava is visible here, as well as underlying and marginal breccias. | | Date: | August 23, 2010 | | Photographer: | Steve Anderson
