My main interests lie in the realm of snow and ice.
Research Interests
Previous projects include investigating wet snow avalanche processes, such as water movement in the snowpack and its implications for wet slab avalanches. Working as an avalanche forecaster for the spring opening of the Going-to-the-Sun Road in Glacier National Park allows me to continue work on wet snow avalanche projects such as glide slab avalanches. I am also interested in investigating ecological change associated with avalanches, avalanche runout probability, and the relationship between climate and avalanches. Other research interests include monitoring mass balance of small mountain catchment glaciers.

Evaluating How Snow Avalanches Impact Mountain Goat Populations in Southeast Alaska
Snow avalanches alter mountain environments and have both beneficial and harmful effects on wildlife. Avalanches can benefit wildlife by creating open areas for grazing but can also be deadly when animals are buried in avalanche debris. Avalanches pose high risks to mountain goats because they inhabit rugged and steep terrain, but the actual impacts of avalanches on mountain goats remain unknown. ...
Wet Snow Avalanche Research
Wet snow avalanches, including both wet slab and glide avalanches, are dangerous and can be particularly difficult to predict because they are relatively poorly understood compared to dry snow avalanches. They pose significant risk to human life and infrastructure in mountainous areas throughout the world. Wet snow avalanches are caused by weakening in the strength of the snowpack, often triggered...
Remote Sensing Tools Advance Avalanche Research
The USGS Snow and Avalanche Project (SNAP) uses remotely sensed technologies to understand snowpack changes that influence water storage, recreation, avalanche hazard and acts as a driver of landscape change. Satellites, uninhabited aerial systems (UAS), and structure-from-motion (SfM) photogrammetry are some of the tools scientists use to collect high resolution imagery that supports ongoing snow...
Examining Snow Avalanche Frequency and Magnitude
Snow avalanches pose substantial risks to human safety, commerce, and infrastructure in mountainous regions across the globe. Avalanches also act as drivers of important ecological change by creating and modifying habitat for flora and fauna. To better understand the dynamic processes of avalanches at multiple scales, the USGS Snow and Avalanche project uses a variety of methods to study avalanche...
Glaciers—Understanding Climate Drivers
Across the globe, glaciers are decreasing in volume and number in response to climate change. Glaciers are important for agriculture, hydropower, recreation, tourism, and biological communities. Loss of glaciers contributes to sea-level rise, creates environmental hazards and can alter aquatic habitats. These are among the cascading effects linked to glacier loss which impact ecosystems and human...
USGS Snow and Avalanche Project
Snow avalanches are a widespread natural hazard to humans and infrastructure as well as an important landscape disturbance affecting mountain ecosystems. Forecasting avalanche frequency is challenging on various spatial and temporal scales, and this project aims to fill a gap in snow science by focusing on reconstructing avalanche history on the continental mountain range scale - throughout the...
Science in Glacier National Park
Glacier National Park (GNP) is considered a stronghold for a large diversity of plant and animal species and harbors some of the last remaining populations of threatened and endangered species such as grizzly bear and bull trout, as well as non threatened keystone species such as bighorn sheep and black bear. The mountain ecosystems of GNP that support these species are dynamic and influenced by...
Time Series of Glacier Retreat
The retreat of glaciers (see PDF at end of page) in Glacier National Park, Montana, has received widespread attention by the media, the public, and scientists because it is a clear and poignant indicator of change in the northern Rocky Mountains of the USA. In 2017, the USGS and Portland State University released a dataset which describes the areas of the 37 named glaciers in Glacier National Park...
Climate Change in Mountain Ecosystems (CCME)
Climate change is widely acknowledged to have a profound effect on the biosphere and cryosphere with many and diverse impacts on global resources. Mountain ecosystems in the western U.S., and the U.S. Northern Rocky Mountains in particular, are highly sensitive to climate change. Warming in western Montana is nearly 2 times greater than the rise in global temperatures over the last 100+ years...
Going-to-the-Sun Road Avalanche Forecasting Program
As the most popular attraction in Glacier National Park (GNP), the Going-to-the-Sun Road traverses scenic alpine zones and crosses the Continental Divide at Logan Pass (2026m or 6,647' elevation). The Park closes a 56km (34.8 mile) section of the road each winter due to inclement weather, heavy snowfall, and avalanche hazards. Annual spring opening of the road is a highly anticipated event for...
Repeat Photography Project
Repeat photography provides objective visual evidence of landscape change. USGS scientists created approximately sixty repeat photography pairs that document glacier change in Glacier National Park. These photograph pairs are available as a collection hosted by the USGS Photographic Library and are publicly available for download. Modern (1997 to 2019) photographs were taken from precisely the...
Brief History of Glaciers in Glacier National Park
The history of glaciation in Glacier National Park spans thousands of years of glacial growth and recession, carving the steep and striking mountain features we see today. Glaciers have been present within the boundaries of present-day Glacier National Park since as early as 6,500 years ago (Munroe and others, 2012). These modest glaciers varied in size, tracking climatic trends, but did not grow...
