Ëdhä Dädhëchą (Moosehide Slide)

Tr’ondëk Hwëch’in Elder Mary McLeod related the origin story of the slide in 1974:

“In early days there were cannibals everywhere and they bothered people. So one time people climb hill near where is now Moosehide to get above them. Lots of big trees on these hills that time. People had only axe made of sharp rock in those days. They cut down the biggest tree with stone axe and they throw that tree down the hill on cannibals. That tree start big slide. It kill all the cannibals. That slide is shaped like hide of moose so people call the place Moosehide.”

It is not known how long the trail across Ëddhä̀ dä̀ dhëchą has been in use. It links two ancient Tr’ondëk Hwëch’in communities, Moosehide and Tr’ochëk, and likely acted as a connection to many other traditional trails. The slide itself is a symbol of home to the Tr’ondëk Hwëch’in. Chief Isaac proudly displayed a drawing of the slide of Dawson on his drum because, as his great granddaughter explains, “the symbol that is shaped like a moose are signs of the land set there for his people to live and to remember.” Chief Isaac can be seen holding his drum in historical photos.[21] The image has also become a symbol for the biennial Moosehide Gathering, an event that celebrates the strength and successes of the Tr’ondëk Hwëch’in.

The slide is thought to have occurred some 1,740 years ago possibly due to a combination of pore water pressure and seismic activity. The slide contains a rock glacier that becomes an earth flow near its base. The slide area is still active as evidenced by tension cracks and split trees near the head scarp. There is concern that another slide may be triggered that will run down into the townsite. With average temperatures increasing, permafrost will melt, increasing the pressure of groundwater held in the soil and between layers of rock. This is what is thought to have triggered the first great slide. The increase in annual snow and rainfall will also contribute to the pore ground water increasing the likelihood of another slide.[22]

The remnants of a flume or aqueduct crossing the slide was the idea of J.A. Acklen. While digging an irrigation ditch to water his crops on the high ground above the Klondike River, he discovered gold. Realizing he could use water under pressure to wash out the gold, he struck upon the idea of diverting water from Moosehide Creek, storing it high above the Klondike Valley, then siphoning it to supply water to his mine. He began work in 1905. He sold his rights to the Guggenheims who eventually completed the project. Acklen was the first to envision hydraulic mining in the Klondike.[23]
