In June 2022, Mendenhall Fellow Sabine Loos (Research Civil Engineer in the Geological Hazards Science Center) presented a seminar to USGS's Earthquake Science Center at Moffett Field, CA, where Max Schneider (Research Statistician) works as a Mendenhall Fellow.

Map showing helicopter survey area and near Granby, Colo. Surveys will not occur directly above populated areas. Black circle indicates study area.

Bruce Bernard (left) and Scott McBride (right) obtain water and sediment samples at Egmont Key which is about 1 mile west of the mouth of Tampa Bay in the Gulf of America. Samples were collected June 14, 2010 prior to the possible occurrence of oil contamination from the Deepwater Horizon's oil well.

Researchers from the USGS, NASA, and NAU gather around a small simple esker and ephemeral lake deposits.  The team used sedimentology, geochemistry, and remote sensing to characterize these features on Earth before comparing them to Mars.

Survey area for low-flying helicopter soon to be visible in six Montana counties, including Helena, the Elkhorn Mountains, Bull Mountain and the Tobacco Root Mountains.

Andy Creighton, USGS Hydrologist. A photo shows USGS scientist Andy Creighton smiling at the camera. Andy is on a pair of dark skis posing in a filed of snow. Behind her, rocky mountains are dusted in snow and evergreen trees. Andy is wearing bright snow gear that includes yellow ski boots, red ski pants, a turquoise hoodie, and a yellow backpack.

Andy pulls the ground-penetrating radar (GPR) behind her on a sled. A photo shows USGS scientist Andy Creighton smiling at the camera. Andy is on a pair of dark skis posing in a filed of snow. Behind her, rocky mountains are dusted in snow and evergreen trees.

Victoria Scholl, USGS Physical Scientist. A photo shows USGS scientist Victoria Scholl smiling off to the right of the photographer. Victoria stands in front of a gravel parking lot with mountains in the background. Victoria is using an iPad and controller to pilot a drone. Victoria wears a brimmed-hat, sunglasses, and a grey T-shirt.

Evan Gohring, USGS Hydrologic Technician. A photo shows USGS scientist Evan Gohring smiling at the camera. Evan is wearing a T-shirt with the USGS logo on it. He is also wearing a ballcap and Evan is standing in front of a stand of aspen trees and a field of snow.

Dr. Andy Creighton, USGS Hydrologist. This graphic shows a quote from Andy’s narrative. It reads: “This is my first permanent government position, now I get to ski and do alpine hydrogeophysics - talk about a dream job!“ Yellow quotation marks bookend her quote.

Mark Bauer, USGS Geographer. A photo shows USGS scientist Mark Bauer smiling at the camera. Mark is kneeling and holding the USGS drone with both hands. Mark wears a ballcap and an orange vest over his green USGS T-shirt. Behind Mark is a field of brown grass and a leaf-less tree sits in the background.

Evan and the team dug a snowpit to collect snowpack data at Berthoud Pass, CO.

Dr. Andy Creighton, USGS Hydrologist. This graphic shows a quote from Andy’s narrative. It reads: “I was the first woman to be a part of a self-sustained snowmachine expedition across the North Slope of Alaska. It was amazing to be able to break down some of those barriers that are still in place for women in science.” Yellow quotation marks bookend her quote.

Mark Bauer, USGS Geographer. This graphic shows a quote from Mark’s narrative. It reads: “The program continued to grow, and as a remote pilot and geospatial analyst, I grew along with it.“ Yellow quotation marks bookend her quote.

Victoria works on the USGS UAS equipment. Victoria is crouched down in the snow, working on the USGS drone. The drone is black with yellow accents. Victoria is wearing dark snowgear and a ballcap. Snow covers the foreground. In the distant background, snowy mountains and a few evergreen trees dot the landscape.

This graphic shows how snow-water equivalent is calculated. A grey jar with a red lid dominate the graphic. Inside the jar is snow. On the top, the snow is loosely layered. On the bottom of the jar, the snow is more compact. Text alongside the right of the jar reads “snow depth.”

In this photo, a group of 20 scientists pose for the camera. The group is dressed in winter gear and stands in front of Berthoud Pass, Colorado. The pass and the ground are covered in snow. Berthoud Pass has a few patches of dark green trees.

In order to get accurate measurements, the Snow to Flow scientists collect several kinds of data using a few different tools. Evan and the team dig snowpits and collect snow depth, snow density, and weather data. They also place sensors across the snowpack to help the drones collect accurate data.
