Bumble bee on a flower
While surveying high water marks in Oakridge, Oregon, bumble bees buzzed around the river banks. The bees often mistake our bright colored equipment and florescent safety gear for tasty yellow flowers.

Image of the Week — Glacier Loss in Iceland
Iceland had 269 named glaciers as of the year 2000 but ice has retreated in the face of warming temperatures. By 2014, OK Glacier in western Iceland had lost so much mass that it was no longer considered one at all. Icelanders now refer to it simply as OK, the name of the volcano upon which it rests.
