Seining for Sturgeon
Biologists at Columbia Environmental Research Center drawdown and seine a pond to collect reproductive pallid sturgeon. The pond has been specially designed to provide turbid, flowing water that pallid sturgeon need to thrive.

USGS 50th Anniversary White House
In 1929, as part of modest ceremonies to mark the USGS' 50th anniversary, President Hoover invited Director George Otis Smith (who succeeded Walcott in 1907), and other USGS employees in the DC area to a reception at the White House. A professional photographer took a panoramic image of the attendees assembled in the Rose Garden.

A Gossan at the Blackbird Cobalt-Copper Mine
USGS scientist Art Bookstrom maps and samples a gossan, developed on tightly folded, mineralized, metamorphosed, and weathered banded siltite, exposed on the southwest rim of the Blacktail pit of the Blackbird cobalt-copper mine, in the Salmon River Mountains of east-central Idaho. The gossan is overlain by unconsolidated colluvial debris.
