Earning a winter merit badge, scouts with Coaldale's Cub Pack 740 spent time Sunday evening at the Seek Park in Coaldale learning how to construct an igloo with only a saw and a few homemade tools. Scout leaders added that this type of shelter was originally built by the Inuit tribes of Canada's Central Arctic and Greenland's Thule areas. Although some Inuit people tended to use snow to insulate their houses, others opted us to whalebone or animal hides. Snow was preferred as the air pockets trapped in it acted as an insulator from the cold. On the outside, temperatures may be as low as minus 49 degrees Fahrenheit, but inside temperatures can reach up to 61 degrees when the igloo is warmed by body heat alone. Gary Royer, Coaldale Cub Scout Master, mentioned that other scout troops he volunteered with even camped out in them. For more information about joining the Coaldale Cub Scouts call Royer at (610) 656-9183. The cub scout pack is open to any boys ages 7 to 10. They meet every Sunday at 4 p.m. and Monday (Kindergarteners and first graders) at 7 p.m. at the Knights of Columbus building in Seek.
