Hint:
It happens when glacial ice stops moving and melts back.

I think we ruled out your common morraines (ground, abelation, medial, etc.) already. Based on my personal encounters with the following critters, we can also rule out: pongos, varves, sun cups, rock flour, debris cones, Roche Moutonnees, drumlins, a furrow, a kame, a kettle, or a till. And it is clearly not a nunatak.

I guess that only leaves an esker?

The difference from what you have and what this is depends on how straight one is.

And I thought It was a Terminal Moraine, like the Giant's Wall in Norway, at least according to the wiki...

No, a lot of time spent flying over Canada, where one navigates from one glacier remain to the next. Which leads to this. What is this, and how is it related to a glacier? For bonus points, what is its name, and name the famous person whose house appears in the photo.

Angela, no and no.

John, yes.

Hint - concentrate on the little blue blob, and the different coloured vegetable matter around it.

Time for another clue. This feature is only about 15,000 years old, and will be gone in another 10,000 years. A blink of the eye, geologically.

No but think along those lines. Remember it is a glacier relic.

Close enough! It did indeed start as kettle, but has become a bog as the water level dropped around here over the last 15,000 or so years. I would have accepted a kettle or a bog.

For those not up on their glaciers, a kettle starts when a passing glacier digs a big old hole in the dirt,and then leaves a few cubic miles of ice in it when it retreats. Once the ice finally melts you are left with a kettle: a dead end lake where water comes in but doesn't come out. (Sort of a roach motel for water.) At first this looks likes an average round lake, but the lack of water exchange means the water becomes slightly acidic, slightly salty, and very low in oxygen. As a result, only certain species of plant will grow in and and around it, and when they die and fall in the water they don't rot. They become a mat of dead vegetation around the edges with plants growing on top of it, that is the pale yellow stuff you see in the photo. Give this yellow stuff another few thousand years and it becomes peat.

For the bonus points,this is Sifton Bog in London, Ontario. My house is in the top left hand corner of the photo ;).
