General Information
Welcome to the 111th Annual Meeting of the Cordilleran
Section of The Geological Society of America, hosted by
the University of Alaska Anchorage and its Department
of Geological Sciences. The 2015 meeting features presentations that cover a wide variety of topics relevant to
the North American Cordillera and Alaska in particular.
Important highlights of the meeting include symposia and
special sessions honoring the scientific contributions of
geologists Dr. Dwight Bradley and Dr. Allison Till, and the
contributions to the art and science of west coast fossils made
by paleo-artist Ray Troll. The meeting also marks the first
Cordilleran section meeting held on the University of Alaska
Anchorage campus, a rapidly growing university with a burgeoning geological sciences program.
The meeting location brings geoscientists together in
Alaska’s largest and most diverse city. Situated at the base
of the Chugach Mountains, Anchorage is built on glacial
deposits associated with the last major ice age. The city is
surrounded on its north, west, and south sides by the waters
of Cook Inlet, a major marine embayment that boasts some
of the highest tides anywhere in North America. To the west
of Anchorage, across Cook Inlet, are the Tordrillo Mountains
and Mount Spurr Volcano, the closest active volcano to
Anchorage. To the north are the high peaks of the Alaska
Range, including Mount McKinley, the highest mountain in
North America. Because of its location, Anchorage is a key
international air hub in the North Pacific region as well as
one of the primary gateways to the Alaskan wilderness.
Venue and Lodging
The meeting is being held on the University of Alaska
Anchorage campus, primarily in the ConocoPhillips
Integrated Sciences Building and adjacent buildings. The
official lodging site for the meeting is the downtown Hilton
Anchorage, 500 W. Third Avenue, Anchorage, AK 99501.
A free shuttle provides transportation between the meeting
venue and the Hilton Anchorage and runs each morning and
late afternoon/evenings.
Dining: UAA Campus Area
There are several eating establishments on the UAA
campus that are within easy walking distance from the meeting venue.
Varsity Sports Grill: Located on the top floor of the
Alaska Airlines Center, this pub is about a 5-minute walk
from the meeting venue. The Varsity Sports Grill overlooks
the main performance/competition arena. This upscale sports
pub features specialty salads, burgers, Alaskan-flare entrees,
and, among other gourmet items, a variety of artisan pizzas.
Creekside Eatery: Located in the Gorsuch Commons,
about a 10-minute walk south from the meeting venue, the
eatery features a wide variety of fresh food, including fresh
fruit and salads; hot, home-style entrées; freshly baked pizza
and pasta; deli choices served on freshly baked breads; ice
cream and freshly baked desserts; and homemade soups.
Kaladi Brothers Coffee: In the Social Science Building,
this coffee house is about a 5-minute walk from the meeting
venue. Kaladi Brothers features local signature beverages and
a wide range of hot and cold coffee drinks. The café serves
a variety of freshly prepared deli sandwiches, salads, pastries, freshly made soups, bottled beverages, and other light
refreshments.
Dining: Downtown Anchorage
There are several excellent restaurants within walking
distance of the downtown Hilton Anchorage, a few of which
are listed below.
Glacier Brewhouse, 737 W. 5th Ave., Suite 110, about
six blocks from the Hilton Anchorage. Wild Alaskan seafood,
rotisserie roasted meats and handcrafted ales; a popular and
well-loved Anchorage restaurant and brewpub.
ORSO Ristorante, 737 W. 5th Ave (next door to
the Glacier Brewhouse), about six blocks from the Hilton
Anchorage. Fresh Alaskan dishes with a unique Mediterranean
touch, Tuscan-style atmosphere.
Club Paris, 417 W 5th Ave., just four blocks from the
Hilton Anchorage. A classic Alaskan steakhouse in downtown Anchorage, Club Paris has been around since the
1950s, but its building dates back to the 1920s. Features steak,
halibut, scallops, prawns, and red king crab.
Simon & Seaforts, 420 L Street, located eight blocks
from the Hilton Anchorage. An Anchorage landmark, Simon
& Seaforts has beautiful panoramic views overlooking Cook
Inlet of Mount Susitna and the Alaska Range. This classic
American grill has been artfully serving quality USDA primeaged steak and fresh and innovative seafood since 1978.
The Crow’s Nest Restaurant is perched atop Tower 3,
in the Hotel Captain Cook, 939 W. 5th Ave., about seven
blocks from the Hilton Anchorage. The Crow’s Nest is known
for its innovative French and New American fine dining
cuisine, and for its outstanding wine list. It offers spectacular
views of Cook Inlet, downtown Anchorage, and the Chugach
Mountains.
Lucky Wishbone, 1033 East 5th Ave., about one mile
east of the Hilton Anchorage. This iconic 1950’s Alaskan
restaurant is known mostly for its fried chicken, homemade
onion rings, milkshakes, old-fashioned malts, and ice cream
sodas.
2015 GSA Cordilleran Section Meeting 25
Snowgoose Restaurant, 717 West 3rd Ave., about two
blocks from the downtown Hilton Anchorage. Snowgoose
overlooks the port of Anchorage, a festive bi-level brewpub
with a deck, serves burgers, pizza, and seafood.
Dining: Elsewhere in Anchorage & Vicinity
Mooses Tooth, 3300 Old Seward Hwy, about 2.5 miles
from the downtown Hilton Anchorage and two miles from the
UAA campus. Very popular pizzeria and brew pub, probably
the best pizza in Anchorage.
Gwennies, 4333 Spenard Road, about 3.5 miles from the
downtown Hilton Anchorage. Another iconic Anchorage
restaurant, best for breakfast.

This tour highlights the history of the Alaska GMC, its
role in natural resource research and discovery in the state,
how samples are acquired, organized, and processed, the challenges of relocating the entire archive from Eagle River to
Anchorage, unique renovations made to the old Sam’s Club
warehouse, how industry and geoscientists utilize the facility,
and the center’s role in educating the general public.

Cenozoic stratigraphy and sedimentology will also be discussed. Once we reach the Homer area we will provide a
brief overview of the stratigraphy and sedimentology of the
bluff exposures between the Ocean Shores Motel and the
“Shellenbaum sand”. Later in the day we will have brief
presentations on sediment provenance and basin margin
uplift history before breaking for dinner. On the second day
of the trip we visit exposures of the lower Sterling Formation

Cenozoic stratigraphy and sedimentology is also discussed.
The trip then proceeds northward and makes stops along
Turnagain Arm and the Glenn Highway to observe strati
graphic rock units and fault structures. In the afternoon, we

volcanic field, and the mud volcanoes of the Copper River
lowland. On the second day of the trip we will drive to
the Chitina area and examine outcrops of the Chetaslina
mass-flow deposit, a large volcanic debris-flow deposit that
originated from a Quaternary age sector collapse probably at
Mt. Wrangell.

Jennifer Nocerino, Geological Society of America,
[email protected]. No Charge.
Part 1: Career Planning & Informational Interviewing.
Mon., 11 May, 8–9 a.m. Your job hunting process should
begin with career planning, not when you apply to jobs. This
workshop will help you begin this process and will introduce
you to informational interviewing. This part is highly recommended for freshmen, sophomores, and juniors. The earlier
you start your career planning the better.
Part 2: Geoscience Career Exploration. Mon., 11 May,
9–10 a.m. What do geologists in various sectors earn? What
do they do? What are the pros and cons to working in aca-
28 2015 GSA Abstracts with Programs demia, government, and industry? Workshop presenters, and
when possible, professionals in the field, will address these
issues.
Part 3: Cover Letters, Résumés, & CV’s. Tues., 12 May,
9–10 a.m. How do you prepare a cover letter? Does your
résumé need a good edit? Whether you are currently on the
job or not, learn how to prepare the best résumé possible. You

landforms in the world. The ~1-km-tall vertical southeast face of El Capitan
provides an unparalleled exposure of the interior of the Sierra Nevada Batho- Kd
lith at the point of interaction among seven granitic units from two intrusive
suites: the intrusive suite of Yosemite Valley and the intrusive suite of BuenaKdo
Vista Crest. This unique, vertically oriented, decimeter-resolution geologic
map highlights this interaction and provides a crucial third dimension to our
understanding of intrusive geometry. High-resolution mapping of such an
Kd using terresinaccessible exposure was accomplished by remote sensing
trial LiDAR and gigapixel photography and was ground-truthed by climbing
and rappelling. This one-of-a-kind geologic map will interest geoscientists
and enthusiasts of national parks alike. 1 color plate (approx. 35" by 39").
