USGS technicians collect water samples for eDNA analysis to estimate foothill yellow-legged frog (Rana boylii) presence at historically occupied sites throughout Oregon. These data are important for assessing the species' status and conservation needs.

This image from a viewpoint at Dead Horse State Park in Utah shows horizontal Mesozoic sedimentary rocks characteristic of the Colorado Plateau. The Colorado River can be seen from this vantage point and this state park is located between Canyonlands National Park to the southwest and Arches National Park to the northeast.

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.

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.
