Old Crow Flats is a large permafrost lowland undergoing rapid landscape change related to catastrophic lake drainage events and landscape-scale shrubification. While post-drainage conditions have been well documented in modern lake basins, little is known about the evolution from young basins to old. Danielle will present the results from her radiocarbon dated macrofossil analyses of the margin and centre of a drained lake basin. By reconstructing the history of vegetation succession and its associated permafrost conditions better comparisons can be made of past and present basin evolution.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"1440\" height=\"1920\" src=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2025\/02\/NCorbiere_OCF_2022_DaniPeat1.jpg\" alt=\"\" class=\"wp-image-8342\" srcset=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2025\/02\/NCorbiere_OCF_2022_DaniPeat1.jpg 1440w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2025\/02\/NCorbiere_OCF_2022_DaniPeat1-225x300.jpg 225w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2025\/02\/NCorbiere_OCF_2022_DaniPeat1-768x1024.jpg 768w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2025\/02\/NCorbiere_OCF_2022_DaniPeat1-1152x1536.jpg 1152w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2025\/02\/NCorbiere_OCF_2022_DaniPeat1-9x12.jpg 9w\" sizes=\"(max-width: 1440px) 100vw, 1440px\" \/><\/figure>\n<\/div><\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Danielle Chiasson will be presenting Post-Drainage Evolution of Wolverine Lake, Old Crow Flats, Yukon.
