What are the meanings of the different parts of the Yukon coat of arms?

Yukon Coat of Arms: The blue and white wavy vertical stripes symbolize the Yukon River, while the twin red peaks represent the mountains and the gold circles stand for the mineral wealth of the territory. The red Cross of St. George honors the early British explorers and traders; the patterned circle centered on the cross represents fur trading. The crest is topped by a black and white malamute dog, which played an important role in the early history and development of the Yukon.
