Join us for this historical and scientific discussion of environmental change in Alta Lake in the past, present, and future. The event will start at 7:00pm and there will be a cash bar. Free to attend.
During the summer of 2014 Professor Ian Spooner and graduate student Dewey Dunnington from Acadia University, working with members of Cascade Environmental Resources Group (CERG), conducted some exciting research on Alta Lake. Using a core sampling technique, they collected intact samples of the layers of sediment on the lake bottom to better understand how the lake and its watershed have reacted to both natural and man-made change. This technique is known as paleolimnology. Most studies only look at the way the lake exists now – paleolimnology allows us to study the history of a lake too. Every centimeter of sediment represents about 5 years, so some of the material in these samples is as much as 400 years old!
Alta Lake is an important ecological component of Whistler Valley, and since western settlement of the region, has been an essential resource for residents and visitors alike. It is also historically significant – so much so that the town itself was called “Alta Lake” until 1975. The history of the lake from a human perspective has been recorded in the pictures and writings of the residents of the valley, many of them kept in the archives of the Whistler Museum.
While we have watched the lake from its surroundings, the lake has also observed us, recording environmental change through the slow accumulation of material as it washes into the lake, year after year. The sediment from the bottom of Alta Lake allows us to better understand how the lake and its watershed have reacted to both natural and human-made change, and will help us evaluate our management strategies going into the future.
On the evening of Thursday, December 4th, Dewey Dunnington will be presenting his findings to the community at the Whistler Museum. To complement this Executive Director of Whistler Museum, Sarah Drewery, will also be presenting on the history of settlement around Alta Lake.
