Bert Petersen
	
Bert Petersen was in charge of deepening the navigation channel at Five Finger Rapids in March 1929. He was able to get parts from Vancouver to repair some broken machinery in about six days. Peterson wired D.A. Muirhead in the Whitehorse White Pass office, who wired the company’s purchasing department in Seattle. The parts left Vancouver on the //Princess Mary// and were transferred from the Skagway wharf to the train depot by car. The parts arrived at the Whitehorse train depot and were transferred to the Alexander Eaglerock biplane, the //Northern Light,// and pilot Patterson took them to a small lake near Carmacks. They were transferred by dog team to Carmacks, and Sandy Grant took them the last 12 miles with a horse and hastily constructed sled improvised by “Slim” Koebke, the handyman at the camp.((//The Whitehorse Star// (Whitehorse), 29 March 1929.))
