Sampling Big Sandy River below Farson, WY

This huge boulder was dropped by a retreating glacier on the north rim of the Grand Canyon of the Yellowstone in Yellowstone National Park, and it is a testament to Yellowstone's icy past.

A USGS scientist prepares a sample to test the effect of antibiotics on denitrifying bacteria within a glove box. A glove box allows scientists to work with samples in an anaerobic (no oxygen) atmosphere, the conditions under which denitrification occurs.

The RestoreNet gardens test seedlings of priority restoration species across the Southwest. This is a recently installed garden located in the juniper woodlands of the Colorado Plateau. The experiemental network will support land managers by providing insight into various restoration techniques, including testing seedlings vs seeds.
