Thanks to Sequoia’s Jim Decker for some amazing drone footage of one of our instruments in action! Watch the US Geological Survey deploy our LISST-SL2 to collect suspended sediment data on the Nisqually River at Elbe, Washington using our LISST-SL2. The river rises in southern Mount Rainier National Park, fed by the Nisqually Glacier on the southern side of Mt. Rainier. It flows west through Ashford and Elbe along Route 706. It is then impounded for hydroelectricity by the Alder Dam and the LaGrande Dam. The sediment being measured is derived from Mt. Rainier glacial melt into the river.
