+ 12 Below and Blinding White: Resolute Air Station in April This northernmost post of the Royal Canadian Air Force lies on Cornwallis Island, 560 miles north of the Arctic Circle. Each spring its airstrip hums with activity. Outgoing planes make about 50 flights, carrying men and a year's supplies to Mould Bay and Isachsen, Resolute's de pendent weather stations (pages 564-5). Last spring the base presented this win try scene. Temperatures climbed to zero a 7 only now and then. Daylight around the clock blanked out the stars; the National Geographic staff men could make pictures at any time. Permanent frost extended at least 675 feet into the ground, as deep as bits have drilled here. Three track-laying snowmobiles stand abreast on Resolute's snow-paved main street. Drivers leave engines running in fear of freeze-ups. Mess hall and barracks stand on the left, radio and operations building on the right. © National Geographic Society Kodachromes by Andrew H.

Fletcher, National Geographic Staff 1,B 549 Drifting Snow Engulfs "+ an Imported Christmas Tree Far beyond timber line, Resolute de pends on airplanes to bring its holiday evergreens. This lonely tree, planted close to the Royal Canadian Air Force flag, bears witness to violent winds that stripped its needles. The dome near the whirling cups of the wind indicator houses the rawin (from radio-wind) receiver. Electronic equip ment within this plastic, translucent shell tracks a balloon-borne transmitter that relays weather information from the upper air (page 551). + Messages from the Skies Pour into This Room Page 548: Information from Resolute's ionosphere station, correlated with that from four other stations in Canada, three in Alaska, two in Greenland, and one in Iceland, allows forecasts of Arctic-wide radio reception 3 to 4 months in advance. Here Edward Leaver, officer in charge, types his daily report. Recorder at right catches radio signals bounced back from the ionosphere, an ionized layer of atmos phere 60 to several hundred miles above the earth's surface.
