of the Eocene Merrill Pass pluton above the Styx River in the
Lime Hills C-1 Quadrangle. The Merrill Pass pluton is one of
multiple suites of igneous rocks in the Styx River map area that
are being investigated to determine the igneous history and
relation to ore deposit formation in a very metal-rich part of
the Western Alaska Range. The Styx River mapping project is
a component of the Airborne Geophysical & Geological Mineral
Inventory (AGGMI) Program which provides basic geological,
geochemical, and geophysical data and interpretations to help State of Alaska
guide and encourage mineral investment in the State’s mineral Department of Natural Resources
endowment. For more information on the Styx River project see

DIRECTOR’S FOREWORD
2013 has been a year of transition for DGGS. During the year several long-term staff members retired or moved
on to new opportunities. Vickie Butherus, Rod Combellick, Dr. Chris Nye, and Bob Swenson are among those who
will be greatly missed. These four amassed a collective 88 years of service with the Division and take with them
a wealth of technical and institutional knowledge. Vickie retired as the division’s Administration Officer in May
after 21 years with DNR. In June, Rod retired as Division Operations Manager after 32 years at DGGS. Chris retired
in October after 27 years with the Division and the Alaska Volcano Observatory, but is continuing his work with
the Division as a volunteer. In November, after 8 years as Director and State Geologist Bob left DGGS to take his
current position as Deputy Commissioner of the Department of Natural Resources. I am privileged to serve as
Acting Director during the search for a new State Geologist and Director.
Alaska’s potential for unconventional energy resources has recently become a focus for industry and for the
many communities struggling with high energy prices. DGGS is leading or involved in multiple projects to provide
baseline information on conventional and unconventional energy resource potential. Transitioning to new forms
of energy will bring new challenges and opportunities to all Alaskans, and also to DGGS as we meet the changing
needs for energy-related information.
2013 was also a transitional year for the minerals industry. Record commodity prices had led to a boom in
exploration activity in recent years, but a downturn in metals prices this year affected the availability of funding
and slowed exploration activity. Metal price fluctuations are a normal part of the economic cycle and when
commodity prices improve, industrial activity will increase. Despite the current downturn in industrial activity,
we continue our leadership role expanding the amount of publicly available minerals resource data in areas
of high mineral potential. Now is an ideal time to provide new geology and mineral resource data to stimulate
exploration activity, and be available for industry when metal prices recover.
Our changing Arctic climate presents special challenges for building and maintaining communities. Many parts of
the state are experiencing increased erosion, storm surges, and thawing permafrost in response climate change.
DGGS is working to provide the necessary data to allow science-based decision making by community planners
and engineers as they work to accommodate a changing climate.
Increasing demand for digitally available data and less reliance on paper maps is challenging DGGS to make data
readily and rapidly available in new and evolving formats. DGGS must move with the speed of business as we
transition to digital presentation of data via geographic information systems, web-based applications, and data
access portals. It will be challenging to meet this demand while maintaining the superior product quality and
unbiased scientific analyses for which we are known. I encourage you to visit our website, where you can see the
new products we are developing, and suggest how we can improve.
Throughout all these changes, the staff at DGGS have continued their dedicated service and commitment to provide
unbiased geologic information, allowing you to make sound, science-based policy and development decisions.
I encourage you to read this annual report to learn more about our people and our programs, and also to visit
our website (www.dggs.alaska.gov), where you can review our projects and find a wealth of information about
Alaska’s geology and r esources.

Volcanology Section
The , established in 2007, focuses on
processes and hazards associated with the more than 50 active
volcanoes in Alaska. The section is home for the DGGS partici-
pants in the Alaska Volcano Observatory (AVO), an interagency
collaboration between the U.S. Geological Survey, University of
Alaska Fairbanks Geophysical Institute, and DGGS. Volcanol-
ogy Section staff conduct geologic studies of active volcanoes
to estimate their future eruptive potential and behavior, thus
aiding in mitigating volcano-hazard risks. Results of these stud-
ies are released as maps and reports. The section also chrtetpat:/e/s

RELATIONSHIPS WITH OTHER STATE AGENCIES
DGGS provides other DNR agencies with routine analyses and
reviews of various geologic issues such as geologic hazards; evalu-
ations of pending oil and gas lease tracts; area plans; competitive
coal leases; geologic assessments of land trades, sales, selections,
or relinquishments; mineral potential; and construction materials
availability. The DGGS Energy Resources Section works closely
with geologic personnel in the Division of Oil & Gas (DOG) on is-
sues related to energy resources and in providing geologic control
for the subsurface oil-related geologic analyses conducted by DOG.
Each year DGGS works with the Division of Economic Develop-
ment in the Department of Commerce, Community, and Economic
Development (DCCED), to report on the status of Alaska’s mineral
industry. The Engineering Geology Section works closely with the
