The Humber river is... suprisingly shallow?

[JUAN EMMANUEL]

On Monday Sept. 12 I had some chances to explore zome of parts of the Humber river in Toronto, Ontario, because soon the weather will turn colder and the river waters wont allow exploration.  

I was walking at a certain part of the Humber river above Bloor St. when I noticed that I could actually see the river's bottom which is made of up shale bedrock. I decided to check the banks from the water. The pictures below were taken when I was in the middle centre of the river where the waters reached up only knee high.

Below Bloor St. the water got mucky and there are several marshes lining up the banks of the river. I didn't see any exposures of the Georgian Bay formation at this part and instead I chose to walk north.

In addition to discovering the shallowness, I also saw a potential exposure of the Georgian Bay formation, although the exposure could use more erosion to remove all the debris.

The area where I discovered the exposure is in a park where all the banks got bulldozed several decades ago to control erosion, which covered most exposures at this park. 

The exposure revealed limestone layers interbedded with shale. Some of these layers got thicker than 15cm. One limestone layer was fossiliferous which I thought could make some nice hashplates. This limestone layer contained gastropods possibly Hormotoma (?). I have discovered a tiny gastropod hash plate once in Mimico Creek back in 2014 near the mouth.  There were also plenty of pelycopods in the layer. I could not recall finding any cephalopods in the entire length of the exposure.

A piece of gastropod hash plate I took home. The shells are preserved as internal molds.

A Cyrtolites ornatus. I found 2 of these and this was the one I took home.

A piece of ramose bryozoa.

A stubby gastropod at the top of the matrix. Could be a Cyclonema.

Hopefully in the future or after this year's winter more worthy specimens can be exposed. I just hope winter will be severe again like back then to cause a deal of erosion.

Nice Report,JE.

Beautiful nature,and a pretty neat exposure.

Thanks for bringing us along.

Thanks for sharing. I'll have to take a wade down there the next time I'm in the viscinity

Ludwigia if you happen to visit Toronto I'd be more than happy to show you around the creeks and rivers in Etobicoke. But just not in winter

Thanks very much for the offer. I may very well take you up on that next time I'm over there. Don't worry. I've survived enough Canadian winters to know better.
