Mountain lions, desert bighorn sheep, mule deer, and a variety of other wildlife live on and pass through the Nevada National Security Site each day. It’s a highly restricted area that is free of hunting and has surprisingly pristine areas.This 22-minute program highlights an extraordinary study on how mountain lions interact with their prey.

The USGS is a science organization that provides impartial information on the health of our ecosystems and environment, the natural hazards that threaten us, the natural resources we rely on, the impacts of climate and land-use change, and the core science systems that help us provide timely, relevant, and useable information.

The Kamokuna ocean entry remains active, with recent lava flows spreading out over the surface of the lava delta. The spot where the lava tube exits the seacliff is visible, and a ramp of solidifed lava has been built here. Lava then flows into a tube on the lava delta, and finally flows into the water at several spots, marked by the gas plume.

This video clip shows HVO geologist Tim Orr sampling lava from an active pāhoehoe breakout on the episode 61g lava flow. The chemistry of these lava samples provides information on the magma plumbing system. Sampling has been a regular part of monitoring Kīlauea Volcano's ongoing Pu‘u ‘Ō‘ō eruption.

Flyover of the southeast Ceti Mensa map. Distinct groups of rock layers, called geologic units, are shaded in different colors, with dark browns representing the oldest rocks and green representing the youngest rocks. All of these rocks formed as wind-blown sand that became trapped in shallow, ephemeral lakes, similar to the wet playas of the desert southwest US.

The Arizona Water Science Center demonstrates new methods in Reach-Scale Monitoring to improve accuracy and measurability of high flow events. By installing pressure transducers and using LiDAR to measure topography data, hydrologists are able to simulate flows with two dimensional models which will help better calibrate stream gages.
