Burn Proceedings of a Symposium to Commemorate the Contributions of Professor J. Ross Mackay (1915-2014) to Permafrost Science in Canada 7th Canadian Permafrost Conference Quebec City, QC 20-23 September 2015 Edited by C.R. Burn Introduction th Professor J. Ross Mackay, who passed away in 2014 shortly before his 99 birthday, was an iconoclastic influence on geocryology in Canada and around the world. A symposium to honour his contributions to th rd our field was held at the 7 Canadian Permafrost Conference in Quebec City, 20 – 23 September 2015. th The Permafrost Conference was embedded in the 68 Canadian Geotechnical Conference. This volume is the record of the symposium. Publication of the conference papers as a full Proceedings will occur, we hope, in 2016. A companion memorial to this volume, a special issue of Permafrost and Periglacial Processes, is currently in preparation. The majority of contributors invited to the symposium were Canadians, but a few international colleagues also presented papers that were chosen to represent particular dimensions of Ross’s career. The papers in this volume were prepared following the instructions and review procedures of the Canadian Geotechnical Conference. The conference organizers provided a template for style and a limit of 8 pages. The papers were submitted for review by a committee before acceptance and publication at the meeting. I am most grateful to Professor Richard Fortier for overseeing the review and preparation of the papers. The papers were published on flash drives given to every registrant but were not paginated or indexed. The pagination of the papers is unique to this volume. Otherwise the papers are reproduced as presented, except that errors incurred during production have been corrected, such as omission of diagrams submitted in the original copy. Copyright to each paper rests with the authors. I am grateful to all of the authors for allowing their papers to be included in this collection. The papers have been arranged into four sections, in which they are presented in alphabetical order of the last name of the first author. They represent: (1) reflections on the life and work of Professor Mackay; (2) regional studies on permafrost in Canada; (3) discussion of hydrologic effects; and (4) examinations of problems in geocryology. In addition to these authors, I am most grateful to Professor Antoni Lewkowicz and Dr Jerry Brown who filled spaces in the program that appeared due to emergencies before and during the symposium.

ROSS MACKAY (1915 – 2014) John Ross Mackay, Canada’s pre-eminent authority on per- mafrost, died peacefully in the early morning of 28 October 2014. He was nearly 99 years old. Throughout the geocry- ological community, Ross was known as an exemplary researcher, an audacious feld scientist, and a loyal and friendly man. For more than three decades from the early 1960s, he was acknowledged as Canada’s pre-eminent Arc- tic scientist. His feld research in the western Arctic began in 1951 and continued without interruption from 1954 to 2011, although he offcially “retired” from the University of British Columbia (UBC) in 1981. He published 201 scien- tifc papers and two memoirs in toto, all but 13 as sole or senior author. His work is the benchmark on thermal con- traction cracking in permafrost and on pore-water expul- sion during freezing of sands. The permafrost community thus knows him best for his work on ice wedges and pingos, but his expertise on terrain conditions in the western Arctic J.

On the journey north from Yellowknife by foat plane, the pilot, Ernie Boffa, had been concerned that the water bodies were still frozen about 200 miles short of their destination, so he turned back and dropped down on a small lake, left Ross and Keith there, and said he would return in a week’s time. Neither Boffa nor Mackay had a map! In 1960, Ross published observations made during that hiatus. The lake now has a permanent name on the maps of Canada. It is called Stopover Lake. During the 1950s, after a season on Cornwallis Island in 1952, Ross began to accumulate feld experience through- out the western Arctic, traveling by boat along the coast east and west of the Mackenzie delta and walking inland. Most of his journeys were by freighter canoe, driven by J. Ross Mackay recording the deformation of an antisyngenetic ice wedge at a 5 or 10 hp motor, and by schooner.
