Kirk Bryan Field Trip

The Kirk Bryan Field Trip has been sponsored by the Division since 2006 to bring together the QG&G community during the Annual Meeting to discuss emerging and provocative ideas in an informal field setting. This one-day trip is usually held the day after (Thursday) or before (Saturday) the meeting. Originally held during the meeting, the large number of Division-sponsored sessions now makes it impossible to avoid scheduling conflicts. The Kirk Bryan is run as a regular GSA Field Trip and must meet GSA requirements and deadlines. As part of sponsoring the field trip, QG&G subsidizes the registration cost for the first 10 students who register for the annual Kirk Bryan Field Trip.

*In light of the QGG-Includes task force's ongoing efforts to improve diversity, equity, and inclusion (DEI) at QGG-sponsored events, QG&G strongly encourages field trip proposals to reflect a strong attempt to be inclusive of persons and topics representing those often marginalized or unrepresented in the geosciences. Proposals that focus on applications of QGG science in Indigenous or Urban landscapes, or those that highlight the effects of natural hazards, including climate change, on communities that are currently underrepresented in QGG sciences are particularly encouraged. We also encourage outreach efforts with local scientists and teachers that can increase experiential opportunities in geological sciences within underrepresented groups. We also suggest proposals include a brief statement that demonstrates how their proposed field trip promotes DEI in QGG sciences.


If you are interested in leading the Kirk Bryan Field Trip, please contact the Chair before proposing to GSA.

Kirk Bryan Field Trip Origin Story

The Geological Society of America national meeting provides a flexible venue for the presentation and exchange of the highest quality research, education, and outreach in the geosciences. Two ways that GSA distinguishes itself in this respect are through Divisions, like QG&G, that regularly solicit, organize, and promote topical or special sessions, and of course through field trips, which are signature events at all GSA meetings. In 2006, following a discussion with then GSA President Stephen G. Wells, a proposal was put forward by Frank J. Pazzaglia for the QG&G division to sponsor an annual field trip focused on raising the scientific impact of the national meeting. The vision of the Kirk Bryan Field Trip was to combine a during the meeting one-day field trip with the full slate of QG&G special sessions to create a meeting within a meeting feeling for the QG&G community. The goals of the field trip itself was to take QG&G participants away from the many (good) distractions of the meeting convention center and assemble them at one single provocative outcrop or landform where ideas could be expressed and shared in an informal atmosphere. Provided that the field trip was scheduled for a Tuesday, the participants could go directly from the trip to the QG&G social and business meeting to continue the networking and discussion. The focus of the trip was to be on ideas, different perspectives, and the seeding of new projects, rather than the showcasing of completed work with a published field guide and several stops. This was the case for the inaugural Kirk Bryan Trip to Hickory Run State Park in Carbon County, PA held in conjunction with the 2006 Philadelphia National Meeting. Eleven years later at the Denver national meeting in 2016, results of a new cosmogenic geochronology study of the enigmatic boulder field at Hickory Run were presented, realizing the original vision. Over the years, many QG&G members have stepped forward to run the Kirk Bryan trip, and its format and vision have evolved. Now, the trip is run as a regular, sanctioned GSA field trip with a formal, published field guide. The trip tends to highlight in-progress or completed work, rather than focusing the community on a single, provocative outcrop or landscape, and it has been held on days other than Tuesday to avoid scheduling conflicts as well as allow for coordination with other GSA special sessions or field trips, as was done for its 10th anniversary at the Baltimore national meeting. However it continues to evolve, the Kirk Bryan field trip offers a great venue for scientific engagement and impact in the QG&G community. Frank Pazzaglia

Leaders: Michel Parent; and Michel Lamothe

Endorsed by: Quaternary Geology and Geomorphology Division (submitted for approval)

Trip Description:

The inferred extent and volume of the Laurentide Ice Sheet during MIS3 has been recently proposed to be much reduced during MIS3 as a consequence of new (Dalton et al., 2016; Pico et al., 2018) but disputed (Miller and Andrews, 2019) chronostratigraphic interpretations over the Hudson Bay Lowland. The concept of a much reduced LIS between 50-30 ka has major implications for the evolution of drainage conditions in the St. Lawrence River valley (SLRV), a river system particularly sensitive to LIS dimensions. The recognition of glacial lake sediments in the SLRV implies the damming and rerouting of drainage and therefore a substantial LIS volume. In contrast, the presence of sediments indicating normal drainage, whether fluvial, lacustrine or marine, implies mostly ice-free conditions in the valley and thus a reduced ice volume. A 2020 Kirk Bryan fieldtrip is thus proposed to visit three sites providing conflicting field and geochronologic data, located at less than 50 km of each other where both types of sediments have been recognized and dated at ca 30 to 50 ka.

The first site will be located at Ulverton where late-glacial subaqueous outwash sediments allow the excursionists to discuss the impact of the presence of continental ice in the SLRV on the depositional systems in the Appalachians. The continuity of glacial cover in the Central St. Lawrence Lowlands through MIS 2-3-4 has been one of the cornerstones of the Late Quaternary stratigraphic record of southern Québec (Gadd et al., 1972; Lamothe, 1989; Lamothe et al., 1992; Occhietti et al., 1996). The second site is located near Pierreville, a classical occurrence for the St. Pierre organic (peat) sediments. At a nearby section, sub-LGM till fluvial sediments exhibiting upriver sedimentary structures are interpreted as distal glacial outwash and correlated to the mid-Wisconsinan Sables des Vieilles Forges (SVF). There, as in several other locations in the central part of the SLRV, IRSL dating of the SVF suggest fluvioglacial sediment aggradation was initiated at ca 40-50 ka (Lamothe, in preparation). The third site will allow discussing the recent discovery, below the LGM till unit and Champlain Sea clay, of a succession of marine sediments overlying plant-bearing alluvial sediments (Parent et al., 2015, 2017) AMS-radiocarbon-dated at 31 270 ± 200 years BP (36400 – 35150 cal BP) and 33 250 ± 240 years BP (38680 - 37130 cal BP). These sediments are from a borehole in which the mid-Wisconsinan marine-alluvial succession overlies an older till unit and laminated lacustrine sediments lying directly on bedrock. The stratigraphic position of the marine unit between the 35 to 39 ka-old alluvial sediments and the LGM till records an hitherto unrecognized glaciomarine event in the central St. Lawrence lowlands prior the last glacial maximum.

This Kirk Bryan fieldtrip will bring participants to classical as well as new sites exhibiting parts of the St. Lawrence valley Quaternary record and should provide them with ample opportunity to discuss the ins and outs of the revised stratigraphic record.
