In March 2014, the Strategic Crevasse Avoidance Team (SCAT) surveyed the treacherous first 70 miles of a route the Greenland Inland Traverse will use to resupply the National Science Foundation's Summit Research Station. During a three-week period, the team utilized satellite imagery, Global Positioning Systems, Ground Penetrating Radars, tracked vehicles, and an autonomous robot to ensure a safe crevasse-free route.
