In the snowpit, Evan collects snow depth, snow density, and weather data at Berthoud Pass, CO.

Two photos are arranged side by side. In the first photo, the photographer stands at the bottom of the snowpit. We can see how deep the snowpit is – about the length of a ski from tip to tail. There is a shelf dug into the side of the pit that holds science gear.

Mark communicates with the ground team (including Evan and Andy) to let them know that the USGS UAS is starting its flight over the snowpack.

Mark checks the spatial data downloaded from the drone to make sure that the first UAS flight accurately collected snowpack data.

The ground penetration radar is set up on a sled, ready to be pulled behind a skier. The sled is covered in blue canvas. The radar is a combination of yellow and black computer gear and a neon green foot-long sensor. Yellow crates and skis dot the background of the image.

While surveying for Oregon spotted frog egg masses in Deschutes County, OR, field technicians caught an adult female using a dip net. This was the first individual observed during the Spring field season.

This graphic shows a snow-capped mountain with the words “From Snow to Flow” written on the bottom left corner. Next to the mountain, hovering in the air, is a illustration of a drone. On the bottom right corner is an illustration of a ground-based satellite.

A graphic shows a snow-capped mountain. The snowpack on top of the mountain is melting into a water glass to show that snowmelt makes its way to water users.

The Snow to Flow team is comprised of a “village” of remarkable scientists and engineers from the USGS Colorado Water Science Center, USGS National Uncrewed Systems Office (NUSO), and the University of Southern California - Viterbi School of Engineering. The team is pictured here at the Berthoud Pass, CO field site on April 18, 2022.

Noa Randall and Rachel Allen are installing an optical turbidity sensor on the mudflats in Wellfleet harbor, to pair with the altimeter run by the Center for Coastal Studies.  The Herring River, which drains into Wellfleet Harbor, is slated to have its 100-yo dam removed in the next 6 months, with the potential to dramatically increase the sediment load and sus
