At about Mile 102 you can see Dellenbaugh Butte, which is also known as The Anvil, or Inkwell Butte. Powell camped here July 14, 1869. The majority of the butte is composed of the Summerville Formation.

SCREE film maker, Ben Kraushaar, passes under I-70 at Green River, UT. The next time he will see a bridge over his boat will be 166 river miles away, on the Colorado River, at Hite, UT.

Two red sea urchins (Mesocentrotus franciscanus) sit on the deck of the R/V Falkor. These sea urchins were collected during the #HuntingBubbles research cruise led by the USGS and Schmidt Ocean Institute, which focused on exploring and understanding methane seeps and the communities that depend on them along the Cascadia Margin.

On August 7, HVO geologists measured temperatures and documented the rock layers exposed as sections of Highway 132 buried by lava during the 2018 lower East Rift Zone eruption are "ripped" (shown here) to reopen the road. USGS photo by C. Parcheta, 08-07-2019.

Northern Fulmars, Black-legged Kittiwakes, and Common Murres have all been tested for and contained harmful algal bloom (HAB) toxins. Since 2015, the USGS has worked with a variety of stakeholders to develop testing methods and research projects to better understand the geographic extent, timing and impacts of algal toxins in Alaska marine ecosystems.
