The ice at the lake is remarkably clear yet its very strong. The carrying capacity of the ice far exceeds the loads we are placing in it.

The ice on the lake is remarkable because its very clear to the point that you feel like you are walking on nothing at all. Yet the ice at the drill pad now averages 2.16 m and its grown 5 cm in the past 2 weeks. The free board has ranged from 8.5 cm to 10.5 cm with little change during despite additional loads such as mud and drill pipes. The average ice temperature is about -10 deg.C which is well below the safe average temperature of -2 deg. C. Between January 22 and April 4, the average thickness along the road to the platform has increased by 44 cm from 104 cm to 148 cm; or 0.6 cm/day. Volker Neth, EBA Engineering, Canada, daily monitors the ice for the project.
