Location map of Bute Inlet and Elliot Creek, British Columbia, Canada. (a) Acolite corrected Landsat 8 OLI scene from 30 July 2021 showing Bute Inlet and the depositional fan formed at the confluence of Elliot Creek with the Southgate River. The locations of the Homathko and Southgate river gauges, in situ turbidity measurements, and transects used for collecting satellite-derived turbidity measurements are also shown. Aerial photographs of (b) erosion in Elliot Creek (source: Kat Pyne, Hakai Institute) and (c) the depositional fan at the confluence of Elliot Creek and the Southgate River (source: Grant Callegari, Hakai Institute) following the 28 November 2020 outburst flood. Locations and facing directions of (b) and (d) shown in panel (a). (d) Map to show the location of Bute Inlet on the west coast of Canada.

In Nov 2020 a landslide into a glacial lake in BC triggered a tsunami & glacial lake outburst flood & eventually a large turbidity current in the sea. In this @jgrearthsurface.bsky.social paper, we look at the sea surface turbidity that resulted.
