Howe Sound is a deep, steep-walled fjord on Canada's west coast. The primary sediment source is the glacially fed Squamish River. In the inner fjord, turbidity currents flow from the sandy Squamish River Delta at the fjord head reaching as far as the Porteau Creek Sill 15 km to the south. Recent observations from the Squamish Delta have shown that turbidity currents of various volumes are generated daily throughout almost a month of the summer meltwater period and flow through very active submarine channels characterized by active upstream-migrating cyclic step bedforms (Hughes Clarke et al. 2012a). Cyclic step bedforms are observed in other turbidity-current environments including the Fraser Delta (Hill 2012; Lintern et al. 2016) and Monterey Canyon (Fildani et al. 2006).
