High-resolution digital elevation dataset for Newberry Volcano and vicinity, Oregon, based on lidar survey of August-September, 2010 and bathymetric survey of June, 2001.

Researchers survey Elwha River elevation and depths. Clockwise from upper left: setting up a traditional survey instrument above the river; measuring river depths from a kayak with sonar and GPS; walking the beach with GPS backpacks; and determining offshore depths using a personal watercraft with GPS and sonar.

Graphic shows an east to west cut-away of Mount St. Helens with an interpreted model of seismic wave speeds under the volcano and earthquakes from 2008-2016. The colors of the model represent changes in seismic p-wave velocities from tomographic studies (Waite and Moran, 2009; doi:10.1016/j.jvolgeores.2009.02.009).

USGS streamgage 13210810, Fifteen Mile Creek near Middleton, Idaho, is one of 10 streamgages the USGS has installed on Treasure Valley drains in cooperation with the Idaho Department of Water Resources. Data from these streamgages will be incorporated into a groundwater-flow model of the Treasure Valley aquifer system.

USGS geologist Amy East was delighted to observe a Chinook salmon carcass upstream from two dams recently removed from the Elwha River in Washington State. River restoration has allowed salmon to reach upstream spawning grounds for the first time in more than a century.

Scientists are studying several weed suppressive bacteria to see if they can be used as a biological control on invasive exotic grasses, such as cheatgrass.
