Fig. S2. Measurement set-up: A vibrator truck pulled by a Pisten Bully (far left), followed by a snow streamer pulled by a second Pisten Bully. The streamer is tied in a loop to reduce spacing between geophone groups from 25 meters to 12.5 meters for higher resolution. Each channel consists of eight gimballed geophones (metal cylinders). The data recording system and operator are located in the blue cabin.
