| Caption: | 3600 yr BP mud flow deposit from Redoubt Volcano exposed on the Cook Inlet coast near the mouth of the Crescent River. Peat section above contains ashfall layers from eruptions since 3600 yr BP. The peat exposed at the base of the mud flow deposit represents the peleo valley floor during emplacement of the mud flow. Photo from field station 16RDKLW004. |

| Caption: | Tree stump in growth position overrun by a mud flow from Redoubt volcano ~3600 yr BP. This is the base of the tree and therefore represents the paleo valley bottom at the time the mud flow was emplaced. Photo taken at the Cook Inlet coast near the mouth of the Crescent River. Photo from field station 16RDKLW005. |

| Caption: | August 1, 2016 overflight of Makushin Volcano's summit crater, roughly 2 km above sea level (6,000 ft). The crater is about 2x3 km and filled with ice, but there is a little hot spot at the top with actively degassing fumaroles and a small lake. We could smell sulfur downwind here, and see a thin, yellow coating of sulfur on the surrounding ice. For better image quality, click the "full size" link below. |
