As Canada pursues net-zero CO2 emissions targets, geothermal energy represents a promising solution, especially in northern Yukon communities such as Burwash Landing. Currently, Burwash Landing relies on importing diesel for power and heating and would benefit from a reliable source of renewable energy. Our study uses horizontal-to-vertical spectral ratio (HVSR) measurements from nine temporary broadband seismometers to refine shear-wave velocity models for the upper 500 m of the crust. These models constrain layering and structure within shallow sediments, depth to bedrock, and discontinuities within the bedrock. These results provide reliable estimates of the thickness of sedimentary cover overlying bedrock. Bedrock depths vary from 50 to 450 m, deepening to the northeast of the Denali fault, and follows a power-law increase with depth through sediments. These insights improve the geological understanding around this portion of the Denali fault and contribute to constructing comprehensive models for the development of geothermal energy in the region.
