We work on the northern Alaskan coast in Prudhoe Bay, North America's largest oilfield.  Typically known to Alaskans as the North Slope, Prudhoe Bay is approximately 250 miles north of the Arctic Circle.   We have to fly on Boeing 737`s for 1-½ hrs just to get to work.  Workers fly out of Anchorage or Fairbanks to get there.   We live in two big camps, each housing approximately  600 workers.  Room and board is furnished.   We work one week or two-week shifts,  12 hours a day, seven days a week.   Weather conditions in winter can dip to -70 deg f below ambient, with wind chills of -100 deg f or more below zero.  Summer temperatures can reach 86 deg f.  The weather can change rapidly.  One day it can be 80 degrees, the next it may be 20 degrees.   We live and work in an Arctic Desert Environment.  There are no trees within 80 miles.   The Longest Day (63 days, 23 hours and 40 minutes).  Sunrise 12:09 a.m. May 20, Sunset 11:48 p.m. July 22.   The Shortest Day (1 hour, and 3 minutes).  Sunrise 11:24 a.m. November 24, Sunset 12:27p.m. November 24.   The Longest Night, (54 days, 22 hours, and 51 minutes).  Sunset 12:27 p.m. November 24, Sunrise 11:18 a.m. January 18.   The Shortest Night (26 minutes).  Sunset 11:43 p.m. May 19, Sunrise May 19, 12:09 a.m. May 20.   Arctic wildlife is abundant.  Polar and grizzly bears are a constant hazard we have to watch out for while working outside.   Pipeline facts:  The pipeline is 48 " diameter, made of 1/2" thick steel.  The oil moves at nearly 5.5 mph, and takes 5 1/2 days to make the journey.  1/10 of all oil Americans use daily passes through the pipeline.  About 2 million barrels pass through each day. If full, the pipeline would hold over 9 million barrels of oil.
