A separate ice road is required for each drilling location on Lake El’gygytgyn. The ice roads are 7.2 km and 5.0 km long to D1 and D2 respectively. The northern location D1, nearest the Lake centre, is isolated from location D2 by an active pressure ridge. It was determined not to attempt any manner of crossing the pressure ridge and crack by the ice safety specialists with EBA Engineering Consultants. This pressure ridge averages 5 meters across and is accompanied with an active crack that averages 1 to 2 meters in width. Additional road markers of bamboo poles were installed every 60 meters along the ice road to D1. The ice thickness along the ice road to D1 was verified with an additional profiling program testing every 0.5 km and the perimeter of the D1 platform was also profiled. This was to confirm adequate ice thickness for the deployment of a bulldozer to clear the snow from the D1 platform. All ice thicknesses exceeded now 1.0 meter. Snow clearing and subsequent flooding of the D1 platform is expected to start immediately.
