Introduction to the special issue: The field tradition in geomorphology

In recognition of the critical role of field observations in the ongoing development of our discipline, the 43rd annual Binghamton Geomorphology Symposium (BGS) celebrated The Field Tradition in Geomorphology. By organizing a conference devoted to this theme, we sought to honor the contributions of pioneering, field-based geomorphologists and to encourage our community to contemplate how field work might continue to provide unique insight into a new, more technologically-driven era. For example, given recent advances in remote sensing methods such as LiDAR, what kind of added value can field work provide? Similarly, how can field-based studies contribute to societally relevant, large-scale questions related to climate change and sustainable management of the Earth system? Motivated by such questions, the 2012 BGS was convened in Jackson Hole, WY, a new, Western location that enabled participation by Rocky Mountain and west coast research groups underrepresented at previous Binghamton symposia. Also, in keeping with the field tradition theme, the 2012 BGS emphasized field trips, including a rafting excursion down the Snake River and an overview of the tectonic and glacial history of Jackson Hole. The on-site portion of the symposium consisted of invited oral and poster presentations and contributed posters, including many by graduate students. Topics ranged from an historical overview of the development of geomorphic thinking to long-term sediment tracer studies to a commentary on the synergy between LiDAR and field mapping. This special issue of Geomorphology consists of papers by invited authors from the 2012 BGS, and this overview provides some context for these contributions. Looking forward, we hope that the 43rd annual BGS will stimulate further discussion of the role of field work as the discipline of geomorphology continues to evolve, carrying on the field tradition into the future.
