Mauna Ulu lava flow on Hawai‘i Island
Mauna Ulu began erupting in May 1969 on Kilauea volcano's east rift zone. Within the first 6 months of erupting 12 lava fountains could be seen, some over 1000 ft high in the air!

Pre-Sample Briefing
Pre-deployment briefing for the Upper Missouri River Pallid Sturgeon Drift Study. Fish biologists and physical scientists from Montana Fish Wildlife and Parks, US Geological Survey, U.S. Fish and Wildlife Service, University of Montana, Nebraska Game and Parks Commission, and US Army Corps of Engineers go over the sample design and assignments.

Processing a Drift Sample
Student Contractor Garrett Cook processes a drift sample collected on June 27 shortly after the free embryos and beads were released. Note the small cluster of pallid sturgeon free embryos and green beads in the lower portion of the sorting tray. These embryos and beads were elements of the Upper Missouri River drift experiment.

Red dye-tracer study in June 2016 on the Missouri River in Montana
USGS scientists conducted a dye-tracer study in June 2016 on the Missouri River about 10 miles downstream of Fort Peck Dam, Montana. The public can expect to see the Yellowstone River turn a similar color in the vicinity of the injection site when scientists conduct a dye study near Glendive, Montana in late June, 2017.

Landsat Monitors 1,800-Year-Old Redwoods
These Landsat images show logging’s influence around the dark green protected forests. Many of the small pink spots in the lower left corner and across the right side of the 1984 scene are logging sites revealed through Landsat 5’s Thematic Mapper sensor.

Oaxaca Cave Sleeper is a newly discovered species
This Oaxaca Cave Sleeper is one of thirteen specimens collected from a cave beneath a reservoir on Mexico's Tonto River. It lacks eyes, is unpigmented, and has sensory adaptations characteristic of fish that live in total darkness. Thuis is the holotype, the example used to describe and name this newly identified species. Credit: Howard L.
