'A' Frame Yarding in B.C. Art Print
A steam donkey utlizing an 'A' frame on a raft is shown yarding logs from the slopes of the Queen Charlotte Islands in British Columbia, Canada. This particular operation was near Slatechuck, in the early 1940s. Logging and manufacturing of airplane spruce in these islands began in 1939.
This 'A' frame was made of spruce logs erected on a huge raft. These floating installations were used extensively to remove timber tributary to navigable waters in B.C. and Alaska. In the 1950s some of these rafts contained over a half-million board feet of logs; their lines reaching out to 2,600'. The larger rafts with larger capacities came into being with the diesel engines after World War II.
