At the Cortes Island Museum: Fossils Left by the Last Glacial Age

Leave a comment

The story of fossils left during the last glacial period is currently on display at the Cortes Island Museum. They are Buchia mussels, Belemnites, and Ammonites—creatures that lived in the Chilcotin region at the same time as the dinosaurs. The rocks containing their fossils were relatively undisturbed for nearly 130 million years. Then, during the last glaciation period, fragments broke off and were carried to Cortes, Read, Sonora, and other Discovery Islands.

In this morning’s interview, Christian Gronau, a retired geologist and Cortes Island resident, tells their story.

Cortes Island 2023 Spring Bird Count & an app called ‘Merlin’

Local naturalist George Sirk was sick for the Cortes Island Spring Bird Count earlier this month, so bird watchers had to rely on a new app to help them identify species. This new app, called Merlin, is one of many topics that he and Nancy Kendel, from the Cortes Island Museum, discussed with Cortes Currents. 

The conversation started out with Kendel (NK) giving an overview:

Success: The search for Western Screech Owls on Cortes Island

Up until now, there have not been any reports of Western Screech Owls on Cortes Island since 2017. That just changed a few weeks ago in the island’s more remote northern forest. 

Field biologist Sabina Leader Mense reports, “I was sitting in the skiff with my husband Dennis, under an unbelievably brilliant sky of stars. It was the last station of the night, pushing midnight, and in the 16th minute of that 17 minute call playback sequence, I heard something. I remember pivoting around in the boat. The sound was behind me and you do what owls do, you turn around.  I think your ears and the muscles and your ears cup and you’re just straining to hear something. Then I heard the call again. It was very distant, but I recognized it was an owl. I began analyzing the audio disks in my head going, ‘is it a Northern Pygmy Owl? Is it a Northern Saw-Whet Owl?’ As I was doing this, it called the third time and I recognized it was a Western Screech Owl.”

When fishing was an industry in Whaletown

A great many fisherfolk once worked out of Whaletown. The Cortes Island Museum’s list goes back to the 1930s, at which point there were 7 men and a woman. Three of them used rowboats. 

“There used to be a huge fleet rafted out, both six and seven abreast all along  both sides of the dock, in Whaletown.  In the last 10 years or so, there’s only been three or four boats in there, fishing. The main one  that I know of in the last little while is the ‘C-Fin,’ but he goes outside of the Vancouver Island area and fishes tuna. When he comes back he doesn’t sell it to a fisheries, he sells it from the dock, and the same with his prawns.  So he’s not using a middle man to sell his products, which I suppose is one of the few ways you could make a little bit of money now,“ said Lynne Jordan, former President of the Cortes Island Museum, in the latest instalment of her history of Whaletown.

Glacier-borne fossils in the Discovery Islands

Over the past 20 years, Christian Gronau has documented a great many fossiliferous rocks in our area. 

Fossil #144 was recently installed at the Cortes Island Museum, but the German-born and trained palaeontologist said, “Palaeontology became a question for me when I was settled here. I looked around, of course was interested in the local geology, and realized that Cortes is just a big pile of granite with very little exceptions to that rule and started wondering what I was going to do with my interest in fossils.”
