This morning was overcast and 14C (57.2F). The forecast was
calling for “intermittent showers with the possibility of a thunderstorm” over
the next 3 days. However, by the time we did our rounds, checked in at the
office & came back for breakfast, the clouds had cleared out. There were a
few campers that have packed up and left already! There are about 100 due to
leave today.
I decide to do the ‘Bat
Lake ’ trail, which is a 6-km loop
which leads through a variety of Algonquin forest types and includes lookout, a
bog and a lake.
Tiny differences in history & structure of soils can
have big consequences for the forests that grow on them. At the beginning of
the trail, we walked through a uniform forest
of White Pine , Balsam Fir and White
spruce. There are no Sugar Maples. This is because the soil is based on sand and
maple seedlings can’t survive in sand.
We walked alongside a “babbling brook” which was very
pretty.
To our surprise, we encountered this large piece of ice,
which must have fallen from the rock above!
We passed through one of the largest and most impressive
stands of Eastern Hemlock to be found in the Parkway Corridor of Algonquin,
nicknamed “Cathedral Grove”. They are important havens for different kinds of
wildlife, ranging from two species of warblers that nest up in the canopy, to
deer that often find winter shelter beneath the snow-catching branches.
After leaving Cathedral Grove, we reached the lookout, which
afforded a wonderful view.
Eventually, we arrived at Bat
Lake , which is a pretty lake.
However, it is one of 15 lakes in Algonquin known to be acidified. The water
here has a pH of 4.8, meaning that it is about 50 timed more acidic than other
Park lakes which generally have a summertime surface pH of around 6.5. Bat
Lake has no capability at all to
neutralize the acid rain that now falls or drains into it, and it cannot
support fish.
Although the mention of an “acidified lake” conjures up
visions of a sinister and sterile wasteland, Bat
Lake is swarming with life. The
most spectacular visitors to Bat Lake
are the Yellow-spotted Salamanders. These exotic-looking miniature dragons
spend most of the year on land. In early spring they return to the water to
breed and lay their eggs. In most lakes, both the adult and salamander tadpoles
would be annihilated by fish. Here in Bat
Lake , however, there are no fish,
which makes it a salamander paradise.
All in all, it was an interesting hike, outlining how the
slight differences in soil can have far-reaching consequences for the forest. However,
we didn’t see any wildlife today.
After returning from the trail, we rested before doing the 2:00 rounds. This time it was fairly easy, with
almost 100 campers departed! The campground went from 123 occupied sites this
morning to 25 this afternoon.
