Arctic War Planes: Alaska Aviation of WW II, Stephen E. Mills, 1978:
"Graveyard of Aircraft
Million Dollar Valley of Crashes
Chapter 4, p. 73
"... On one occasion, two squadrons of B-26 Marauders headed north from California and one month later, the first plane arrived in Fairbanks. Many of the planes crashed in a mountain pocket northwest of Watson Lake, Yukon Territory, that became known as 'Million Dollar Valley.' When the last of the twin-engine bombers arrived in Fairbanks, 45 days since the start north, a total of 13 had failed to make it."
