A drill rig at the Mallik test site in Canada's Mckenzie Delta.  USGS joined the Geological Survey of Canada, JAPEX, and the Japanese National Oil Company to drill test wells for natural gas production from gas hydrate deposits.

During Ocean Drilling Program Leg 204, nine sites were cored and wireline logged on the Oregon continental margin to determine the distribution and concentration of gas hydrates in an accretionary ridge setting, investigate the mechanisms that transport methane and other gases into the gas hydrate stability zone, and obtain constraints on physical properties of

This image shows an inukshuk, a stone cairn used by indigenous peoples in northern latitudes, particularly in places like northern Canada. 

Overall perspective view of the Los Angeles Margin and Basin looking northeast. The distance across the bottom of the image is about 100 kilometers with a vertical exaggeration of 6 times. The margin is bisected by a series of large underwater canyons, channels, and gullies.

Example of wellhead plumbing typical of public wells sampled in a USGS study of 932 public wells nationwide. About 105 million people—or more than one-third of the Nation's population—receive their drinking water from one of the 140,000 public water systems across the United States that rely on groundwater pumped from public wells.

Right steps in the Denali fault trace on the Canwell Glacier caused large rhombehedral chasms to form. Patty Craw in background. This photo was on the front page of the Anchorage Daily News.

Fault trace on Gakona Glacier. Tracks are from where geologists measured the fault offset.

View northward of mountain near Gillette Pass showing sackung features. Here the mountaintop moved downward like a keystone, producing an uphill-facing scarp. The main Denali fault trace is on the far side of the mountain and a small splay fault is out of view below the photo.
