Edward Henry Holbrook Sr. (1891 – 1970)
	
Edward and his brother Frank Holbrook came from California and arrived in the Yukon, via Fairbanks, in 1929.((Don Barz, //Yukon Wanderlust.// Celticfrog Publishing, 2021: 66-67.))\\

A Guggenheim dredge, on Walker Fork in the Fortymile district of Alaska, was constructed in the winter in 1907-08. It was dismantled and moved to Miller Creek in Canada in 1912.((Don Barz, //Yukon Wanderlust.// Celticfrog Publishing, 2021: 66-67.)) The dredge had been shut down for some years in 1933. Ed Holbrook leased it and reconditioned it to dig what Ed believed was the continuation of the rich Miller Creek pay streak in the Sixtymile valley. The dredge was unique in the Yukon River basin, burning 7 cords of wood per 24 hours and giving 125 pounds of steam for the 140-hp steam engine.((H.S. Bostock, //Pack Horse Tracks – recollections of a geologists life in British Columbia and the Yukon 1924 – 1954.// Yukon Geoscience Forum, 1990: 103.))\\
	
The family-operated Holbrook Dredging Company was run by Edward and Frank, and Edward Holbrook’s son Bud. The steam-powered wood-burning dredge was converted to diesel power in 1937. Bostock reported that the company was under receivership in 1939, but it continued to operate under the management of W.A. Williams until 12 November 1942. Due to the war, in 1943 the company was unable to hire enough workers or obtain the necessary parts to continue operating.((Don Barz, //Yukon Wanderlust.// Celticfrog Publishing, 2021: 66-67.))
