Strange Medicine in Jasper is a fairly short, easy read about
a lake in Jasper, Alberta called Medicine Lake.
The lake is unique because it fills up every spring and empties every
fall.
Medicine Lake is located in Maligne
Valley in Jasper National Park in Alberta.
The lake is considered a mystery that many people have tried to solve
for many years. It is unique because it fills
up every spring, primarily from the melting snow, and then empties in the fall
in a strange way. There is no visible
outlet to the lake but instead, it drains through cracks and sink-holes into a
large set of karst. Karst is a system
that forms when water dissolves soluble bedrock, like limestone that the Medicine
Valley is built on. It is said that this
karst system is one of the most complex in the world. When the banks of the lake overflow, it
brings back the legendary Excalibur (a class V+/VI rapid that appears right at
the lake’s outflow). The power behind the Excalibur can be strong
and the last time it ran at a paddleable level for white water paddlers was in
1992. There usually isn’t as much
activity except in the summer of 2012 when the water spilled out of the lake,
pushed through the nearby forest and filled the dry riverbed to bursting for
about five weeks. Zac Ruttiman and Ethan
Begley, both 17 years of age, were amazed when they first saw Excalibur. They say that Excalibur is going to run a lot
more often in the future because of climate change increasing Jasper’s
snowpack. Many other kayakers come to
try to experience this adventure.
I was able to connect with the
article because I travelled to Alberta and British Columbia this year during March
break with a friend. I saw that there are a lot of beautiful lakes and rivers,
mountains and trees. By reading this
article, I learned about the karst system and how it works. The article has made me think about maybe
going back out west in the summer and trying some of the summer activities.
