are being offered in association with ISAES X. Single and half-day
trips are being organized and information on those will appear
here soon. Field trip destinations and topics are relevant to
the ISAES X themes and many feature settings that offer analogs
for contemporary research in Antarctica.
The excursions represent a singular opportunity
for Antarctic geologists from all around the world—whose
research sites typically are separated by vast distances-- to
engage in field studies together, focused upon premier North American
localities that are internationally recognized as exemplary of
fundamental geological processes or associations. The primary
relationships in the field are expected to stimulate discussion
and exchange of information among participants about their current
research in Antarctica and elsewhere. We invite your participation!
For specific information regarding a multi-day field trip, please
contact the excursion leader directly at the email address provided
below. For information about single-day trips, to offer suggestions,
or to submit a field trip proposal, contact Christine Siddoway
(below). Responses to Frequently Asked Questions [FAQ]
are listed at the bottom of this page. Prospective participants
should be aware that, because it is more economical for international
travelers to integrate regional air travel into their international
flight bookings, the cost of air travel to/from the point of origin
for the field trip is not included in the stated cost of each

Colorado Plateau and Grand Canyon
The Colorado Plateau field trip will visit classic geological
localities of the Southwest USA, where the arid climate lends
to superb exposure of Neoproterozoic, Paleozoic, and Mesozoic
stratigraphy in “red rocks” landscapes. Destinations
will include Laramide monocline structures and sites of Tertiary
volcanism, with stops at Salt River Canyon, Monument Valley, the
Comb Ridge Monocline and other sites of interest. The excursion
will culminate with a full day at the Grand Canyon, allowing the
opportunity for self-paced hikes and geological explorations.

Cost: $385.00. This price includes transportation, lodging, and
breakfast. Other meals are to be paid by the participants. Participants

FIELD TRIP INFORMATION
The Rio Grande rift and Valles
Caldera Investigation of active continental rift
tectonics and magmatism
This excursion explores rift architecture and active volcano-tectonic
elements of the northern Rio Grande rift in New Mexico and Colorado,
USA. The eastern rift flank formed by the Sandia and Sangre de
Cristo ranges will be examined, together with intrarift volcanism.
The excursion will offer a transect across the spectacular Valles
Caldera, site of 1.6 to 1.2 Ma ignimbrite eruptions, resurgence
and recent events as young as 60 ka; and the opportunity to assess
the role of inherited crustal structures such as the Jemez Lineament.
Some of the sites of geological importance also have cultural
significance for ancestors of the Pueblo peoples of New Mexico
and offer insight on the impacts of climate change upon human

Cost: $380.00. This price includes ground transportation, lodging,
breakfast and lunch meals. Dinner meals are to be paid by the participants.
Accommodation: Motels and rustic conference centers.
Maximum number of participants: 40.
In Darwin's Footsteps: The Geology
of Tierra del Fuego
The focus of the In Darwin’s Footsteps field excursion is
the tectonics, stratigraphy, and glacial geology of Andean and
extra-Andean Tierra del Fuego. Participants will learn of the
glacial geology and active tectonics along the South America-Scotia
plate boundary of Tierra del Fuego; see the landscape as Darwin
did from the deck of the Beagle and from her boats, and visit
localities described and mapped by Charles Darwin during the voyage
of H.M.S. Beagle. Tierra del Fuego, the southernmost landmass
outside Antarctica, located at the core of the globe-encircling
westerly wind system, offers a setting in which to examine first
hand the interplay of climate and tectonics in this “Uttermost
Part of the Earth” where opening of Drake Passage was likely
the final key to continent-wide glaciation in Antarctica. The
excursion is being co-sponsored by The Geological Society of London.
March or October 2007. Duration: Two weeks, with possibility of
one additional week (see below*). Start/end* location:
Ushuaia, Argentina. Excursion leader: Ian W. D. Dalziel, University
of Texas – Austin, email@example.com
Location: Argentine Tierra del Fuego, South America.
Estimated Cost: $2850.00. This price includes lodging, meals and
ground transportation; based on availability and cost as of May
RT air fare to/from Ushuaia is the responsibility of the participants
and is estimated at $1850 to $2000.
Accommodation: Hotels, inns, and cabins.
Maximum number of participants: 25.
Itinerary: From Ushuaia, Argentina, travel to
extra-Andean Tierra del Fuego by coach crossing the Scotia-South
America active transform plate boundary; visit the Andean foreland
fold thrust belt along the Atlantic coast and see the glacial
deposits of the Lago Fagnano basin along the plate boundary. Travel
by boat along the Beagle Channel towards the eastern tip of Tierra
del Fuego to visit localities of the Lower Cretaceous turbidites,
which infill the Cretaceous Rocas Verdes marginal basin—Darwin's
“clay-slate rock.” Drive west to see the metamorphic
basement of the southernmost Andes near the Argentine-Chile border,
including the core complex of Cordillera Darwin, formed in the
arc-continent collision that initiated Andean uplift in middle
*There is a possibility of chartering a vessel for an optional
week west along the Beagle Channel to Cordillera Darwin will cost
~$2800 USD inclusive of a bunk on the boat and all meals as well
as transportation. Participants may be responsible for an additional
cost to travel to the point of embarkation.
day and half-day trips
Planning is in progress
for local field trips in southern California, to be offered on
the weekend preceding and the weekend following the meeting. In
addition, a half-day trip on local
geology will be offered on Wednesday afternoon.
As an alternative to excursions with a scientific focus on the
Wednesday afternoon of the Symposium, an array of tourist outings
and social events will be offered.
1. Why isn’t air
transportation included in the field trip arrangements?
Reason 1: It is more economical for international travelers to
integrate regional air travel into their international flight
bookings, therefore the cost of air travel to/from the point of
origin for the field trip is not included in the stated cost of
Reason 2: Conference participants commonly have funding from grants
or place of employment for the expense of the actual symposium,
but not for participation in field trips. Typically for an international
plane ticket to USA, there is a very small difference in cost
for the total fare between a final destination at the conference
venue versus the point of departure for the field excursion.
2. The exceptional geological feature that I want to visit is
not featured for a field excursion, but it is absolutely classic
and in terms of distance is comparatively near to Santa Barbara.
Why isn’t there a trip to … ??!!
Response 1: Weather conditions, accessibility, and trip logistics
have been taken into account in selecting trip destinations. Many
superb California localities are not suitable for August visits
(e.g. Death Valley due to extreme temperatures; e.g. Point Sal
ophiolite due to restricted access on a military base).
Response 2: Researchers who are active in the U.S. Antarctic program
can reasonably be called upon to organize and lead the field excursions.
If access and weather are not considerations, then the probability
is that no USAP researcher with expertise in that area of interest
could be identified.
