  • "Messages from Nome to the states went over three handlings: radio, telegraph, and submarine cable. The U.S. Signal Corps made several attempts to link Nome via a submarine cable across Norton Sound to St. Michael, but the constant shifting of the ice across the seabed floor repeatedly carried the cable out to sea. With no other option available, the Corps turned to the relatively new technology of 'wireless telegraphy'; it built 200-foot towers at each end of Norton Sound, 133 miles apart, and successfully made Nome a part of the system. The radio link, however, was not without its own temporary problems. A blizzard in 1904 tore the roof off the station on the Nome side, filling the room up with snow and killing the fire in the potbelly stove that kept the operators warm. In a matter of seconds the temperature inside the station dropped to nearly 70 below and the water in the 6-horsepower gasoline engine that ran the generator froze, cracking the cylinder."
