An accompanying note reads: "SMD - please ensure this cannot reoccur.", and a photo caption reads: "pierced bags are resulting as an environmental problem as fibre is beginning to build up in certain containers." One of the photographs depicting the Cassiar Transport Division was used for promotional posters with the following commentary: "The Cassiar Transport Division operates out of Whitehorse, Yukon Territory and is responsible for delivering the asbestos to the White Pass and Yukon Route terminal in Whitehorse. Fuel oil and supplies are backhauled to the mines. By the end of 1967, the fleet will consist of 65 tractor-trailer units, each of which will carry 23 tons of asbestos. The distance from Whitehorse to Cassiar is 357 miles and Clinton is 403 miles. During the past year, the Division's trucks traveled 2,213,534 miles and handled 75,100 tons, and the mileage to 3.5 million miles. This is a year-round operation and convoys arrive at the mine daily in spite of the long difficult haul. The Division currently employs 43 drivers and 35 mechanics and operates its own maintenance and rebuild facilities in Whitehorse. Over the years these men have established and enviable record of safety, cost and performance."
