Icebergs in Winnipeg – Trimeric


Icebergs in  Lake Winnipeg sometimes have stripes, formed by layers of snow that react to different conditions.

Blue stripes are often created when a crevice in the ice sheet fills up with melt water and freezes so quickly that no bubbles form.

When an iceberg falls into the lake, a layer of water can freeze to the underside. If this is rich in algae, it can form a green stripe.

Brown, black and yellow lines are caused by sediment, picked up when the ice sheet grinds downhill towards the lake.

The water froze the instant the wave broke through the ice. It is the coldest weather in decades.  Water freezes the instant it comes in contact with the air.  The temperature of the water is already some degrees below freezing.’



My mother-in-law sent me these photos with the explanation, aren’t they awesome?

From where did you herald, huge chunks of ice?
Beckoning folks to stop and look twice.
Stripes like mint candy or pretty blue glass,
Carved out of nature, grew up in first class.

Beckoning folks to stop and look twice,
Marvel at bear’s flotation device.
Aesthetically pleasing, it’s sure to entice.

Stripes like mint candy or pretty blue glass,
Formed from melted water freezing too fast.
Will these magnificent icebergs last?

Carved out of nature, grew up in first class,
Towering strength, formidable, incredible.
Giant Kendal mint cake totally edible.

I had so much fun writing this poem thanks to the great photos and Jeanne’s Trimeric poem.

I find it easier to study which lines need to be used from a poem rather than a ‘how to write a Trimeric poem’ website. Who fancies having a go? Do you like the icebergs?

  1. Catherine,
    These photos and the explanation are wonderful! I have never heard of this. I have not read your poem yet because I want to see what I can come up with (if anything…..given time crunch issues)….but THANK you for these photos. We taught a unit on the Polar Regions which is where I learned so much about penguins and Antarctica plus, of course the Arctic region, too. Will come back to read your poem soon.

  2. Catherine:
    A wedding of science, photography and poetry liturgy!
    Glad you and I are on the altar together!

  3. I got these as an email forward too. What a delightful poem you’ve written about them. I especially like “Stripes like mint candy or pretty blue glass.” That’s exactly what they look like!
