Jack snapped these shots after going through numerous snow drifts before he got into Prudhoe Bay.  The engine is operating fine and he didn’t need to do anything, but it’s interesting to see how the snow gets into all the available spaces.  The keypad looking thing is actually the air intake for the cab and the vent above it is the intake for the motor.  Even though the engine is 200 degrees plus it’s still not enough to melt the snow at these temperatures, about 20 or 30 below.
