AbstractThis map illustrates the surficial geology of Iqaluit, Nunavut's capital city. Rather flat, sandy and gravelly glaciofluvial and glaciomarine sediments extend under the airport and its surroundings as well as in Apex. Precambrian bedrock with partial and uneven till cover is found under newly built areas on hilly terrain and plateaus. The area is underlain by continuous permafrost, which causes important technical challenges for the maintenance of infrastructure. A larger scale view of the airport sector emphasizes patterned ground features and the networks of frost cracks.
