I established an outline of the tectonic history of the North American Cordillera
from 40-50 Ma, based on data from my thesis work, compiled with other recent
regional data; (the tectonic setting for this episode of volcanism has long
been a puzzle). I have conducted surficial and bedrock geologic mapping to outline
geologic and environmental hazards related to landslides, and to provide information
for land-use planning near Vail Colorado, in the Vail East quadrangle, and minor
work in the Vail West quadrangle, where I mapped previously unrecognized post-Pinedale
landslide deposits that swept across the western end of the Vail Valley.
Research Summary: I am a research scientist with the U.S. Geological Survey, and have
a Ph.D. in geology. My present position is project chief of the "Landscape
change on Native lands, southern Colorado Plateau". I’m currently
working on the Navajo Nation, and am involved in studies of drought impacts,
wind erosion, and water quality. I’m of Crow descent, originally from
an area on Wyoming-Montana border, where I grew up riding horses. I lived in
the Joint Use Area of the Navajo Nation for ten years, in what is now Hopi Partitioned
Lands, and am mother to three children who are registered voters in the Tolani
Lake Chapter of the Navajo Nation.
Current Research: I’m working to provide communities on the Navajo Nation
with information on geologic hazards, water availability, soils, plant habitats,
and environmentally sensitive areas. Limited, shallow water resources in the
region are sensitive to fluctuations in climate and over utilization. Water
quality can be affected by the local geology or local system contamination.
Easily eroded deposits in the region are highly sensitive to fluctuations in
precipitation intensity, percent vegetation cover, and local land use practices.
I hope to complete the geologic mapping required to establish local conditions
of landscape mobility and stability, and their relation to local environmental
Future Research: I plan to continue working on the Navajo Nation, particularly
on the impacts of drought, and redefining the factors that contribute to drought,
and the landscape response to drought conditions. In addition, I hope to act
as consultant to other tribes, such as my own Crow people. I’ve learned
that if Indian people are engaged in earth science work, it can empower communities
to think and act for themselves, to address the land use and natural resource
issues that challenge all of us.
Academic Preparation: I have a B.S. in geology from Northern Arizona University,
with an extended hydrology emphasis, an M.S. in Earth Sciences from Montana
State University in sedimentlogy of volcanic systems, and a Ph.D. 1999 on the
geochemistry and geochonology of the Absaroka Volcanic Province.
Hobbies: I am an avid long distance runner. It keeps me focused, and helps
during stressful times. I also enjoy doing beadwork, painting and drawing.
