The document discusses the characterization of complex deep-seated landslide deformation at the Little Smoky landslide in Alberta using corner reflector InSAR technology. It covers an overview of the site, the design and installation of corner reflectors, and presents results from differential InSAR coherence images. The study involves contributions from multiple organizations, including the Alberta Geological Survey and the Canadian Centre for Remote Sensing.
