"The purpose of this guidebook is to describe the influence of permafrost on landscape of the Yellowknife region, and to illustrate how our geological legacy has shaped the land that we live on today. It is increasingly evident that permafrost, which provides a foundation for northern ecosystems and communities, is not permanent. In many areas, permafrost is thawing in response to natural environmental disturbances, due to human activity through the development of infrastructure, and by climate warming. Understanding how these changes impact the environment and infrastructure are critical to the resilience of northern society"--Abstract, page 3.
