The Great Esker

July 7, 2018

This week I bought the Bruce Trail App for my phone and so it got it’s first workout.  After identifying a section we hadn’t been on before we set out for the parking area on the map (8th line north of 22 Side road, north of Georgetown).  There are several places that you can pull off and park that are not on the map including where the main trail crosses the road a little farther north.  With the tracking feature turned on it marked our trail as we progressed and created a record of the hike that can be saved toward earning trail badges.

Great Esker

We entered on the Eight Line Side Trail and made our way to The Great Esker Side Trail.  Along the way we identified the remains of an old car in the woods.  It has clearly been there for decades as it has no motor and is surrounded by mature trees. It is in a very advanced state of decay.  The front bumpers and grill pattern were quite unique in the various car models of the 1940’s.  Having looked through hundreds of online picyures, positive identification wasn’t possible but the closest candidate was a 1946 Chevy Stylemaster.  That particular car was a sedan and this model was most likely a truck.

Flowering Raspberries grow along the trail in many places.  Their flowers are quite large for the raspberry family and have a long period of blooms which also makes them of special interest to honey bees.  The fruit looks like a large flat raspberry and is used by mammals and birds.

Eskers are glacial deposits that run in nearly straight lines and rise above the surrounding landscapes.  They are formed during the melting phase of the ice age when water is rushing in a river either over or under the ice.  The formation of eskers is described in greater detail in our earlier post The Brampton Esker.  The Great Esker Side Trail runs, in part, along the top of an esker.  It stands about 30 metres above the surrounding terrain but is much shorter than the one in Brampton.  As far as eskers go, the Great Esker isn’t so great.  The Thelon Esker is almost 800 kilomtres long.  The trail leads directly up the esker.

The escarpment is made up of limestone and harder layers of dolostone.  Scattered throughout the landscape are large granite boulders that appear to be out of place.  They have been carried by the glacier and deposited across the province by the retreating ice sheet.  Rocks that are different sizes or minerals than the ones common to where they are found are known as glacial erratics.

Old stone fences run through the trees marking off the earlier fields.  More recently some guide wires have been put in some places along the trail.  These are growing into the trees in several spots.

Most of the mayapples, or mandrakes, have been harvested by the local wildlife but a couple large ones remained that are still green.  When they start to turn yellow they will put off a pungent odor that attracts raccoons. It is suggested to remove the seeds if you do happen to harvest some of this native fruit.  You’ll have to be lucky because the raccoons check daily for the newly ripening fruit.

Butterflies abound along the trial and this Appalachian Brown was one of several flittering among the plants.

The poison ivy doing very well along the sides of the trails.  Urushiol oil in the leaves and stem causes an allergic reaction in 85% of people.  It is white when the stem is broken but turns black upon exposure to oxygen.  The oil is highly concentrated and a drop the size of a pin head can cause an allergic reaction in 500 people.  In the United States about 350,000 people a year get a rash that can last for up to 3 weeks.

One of the truly interesting boardwalks is this one that takes advantage of this tree and the massive root system to carry the trail.

Snow’s Creek Falls are located at the intersection of 27th side road and the 8th line so we made a detour to see how much water was there at this time.

It was certainly cool to check out the Great Esker Side Trail and take the Bruce Trail App for a test run.  It likely means more hikes on the Bruce in the near future.

Hiking the GTA #100- Pernicious Plants and Beautiful Blossoms

April 28, 2014 to July 18, 2015

Presented below is a gallery of plant, flower and fungi  pictures taken during the first 100 hikes on the journey called Hiking the GTA.  This post concludes our celebration of chapter one in this adventure.

On July 21, 2015 I published my 100th post in this blog under the title Hiking the GTA #100 – Greatest Treks.  That post presented the 15 most popular stories on the blog, so far.  I’ve posted a gallery of animal pictures from those first blogs under the title Hiking the GTA – Amazing Animals.  Ontario has many edible plants, some very beautiful ones and several really nasty ones.  The pictures below are in no particular order except that the three most common poisonous ones are presented first.

Giant Hogweed is one of the nastiest plants in Ontario.  It can cause severe burns and even blindness.  These picture shows last year’s stocks and this year’s white blossoms and was published in the Canada Day post on July 1, 2015.

Wild Parsnip is another plant with similar poisonous sap to the Giant Hogweed.  This picture was taken in Riverwood Part 1 – The Bird Property on June 28, 2014.

A third poisonous plant is Poison Ivy.  This patch was photographed at Barbertown on Aug. 23, 2014.

Burdocks have a tiny hook on the end of each stem that inspired velcro.  This one, complete with Lady Beetle, was photographed at The Winding Lane Bird Sanctuary on Oct. 11, 2014.

Coral Mushroom are one of the plants that although relatively rare can be eaten.  This fungi was discovered on Canada Day 2015.

IMG_6023

Ontario’s provincial flower is the Trillium.  These were seen on our hike from Old Mill to Lambton Mills on May 17, 2014.

The Yellow Iris is an invasive species that takes over our wetlands and chokes out other plant life.  This patch was seen on June 14, 2014 near Raymore Drive.

IMG_2190

Dog-Toothed Violets were seen on the hike where we discovered the Ovens Above Old Mill on May 10, 2014.

The Vipers Bugloss has a brilliant shade of blue.  We found this example during our hike at the Devil’s Pulpit on July 11, 2015.

We found young teasels growing at Glen Williams on June 27, 2015.

Jack-In-The-Pulpit plants can live up to 100 years.  We found this large plant growing in Palgrave on May 30, 2015.

Forget-Me-Nots were used in Newfoundland for their Remembrance Day celebrations before they joined confederation and adopted the poppy.  There were photographed near the Barber Paper Mills on June 6, 2015.

Coltsfoot is one of the first flowers seen in spring.  We found this patch at Churchville on April 3, 2015.

IMG_3227

Canada Thistle isn’t native to Canada but appears on our Coat of Arms.  This bee was collecting pollen on a Canada Thistle near the Erindale Hydro Electric Dam on Oct. 19, 2014

IMG_0730

Black Willow trees grow in wet areas and reach massive sizes.  This one is in Riverside Park in Streetsville where we visited on Sep. 6, 2014.

IMG_3181

Trees suck the chlorophyll back out of the leaves and store it in the woody parts of the tree for re-use the next year.  These trees appear to be doing just that.  These were also photographed at The Winding Lane Bird Sanctuary on Oct. 11, 2014.

Our parks are full of a wide variety of plants which keep the woods alive with splashes of colour from early spring until late fall.  Watch out for the pernicious plants and enjoy the beautiful blossoms as you have your own adventures, Hiking the GTA.
