Bettles air from fairbanks to bettles and from bettles to circle lake.  Then from Takahula lake back to bettles.  I think the flight to circle lake was about $500 and the same coming back from Takahula, but I didn't keep close track as it all went on the credit card if you know what I mean.  I think it was about 250 from fairbanks to bettles and i don't remember if that's roundtrip or not.   
  
 
 
  
Mostly rain, but never really a downpour.  lots of days of drizzle and mist that kept the rock wet.  we did get about a foot of snow in one system which pinned us down on one side of a pass.  It took about 2 days of strong 24-hour sun to clear most of the snow off the rock.  
  
Is the 6" figure for the Arrigetch, or an average for the whole park?
