Two USGS scientists study rotary drill core that was abandoned on location at a porphyry-style copper mineral deposit in a remote part of the Yukon-Tanana upland northeast of Northway, Alaska. The core was left on site by the mineral exploration company who conducted the drilling, and it has been exposed to Alaska weather for almost a decade.

Surveying the Taan Fjord tsunami runup
USGS scientists investigate trees knocked over by the tsunami at the mouth of Taan Fjord. Flow depth here was likely 5 m based on the height of branches stripped off trees in the background. This event had the 4th highest tsunami runup ever recorded.
