Pipes sticking up in the back yard?

[Christine]

Hello,

Does anyone know what these pipes could be? The house is in Edmonton and age is 1957.
My experience from homes in Vancouver is that this could be an oil tank...

Abandoned trans Canada pipeline from the ice age and Pre-Trudeau’s era.
Remember?…when things were good in Ab.

It's a hole in one ..

Come let’s have some fun with this. Funniest ‘guess’ wins!

Perhaps an underground grow up or moonshine operation

Perhaps not an oil tank because there are two pipes and far from each other.

Clothes line posts. (This is not a joke guess.)

I'd guess one may have the city water shutoff, and the other could be a vent for an old plumbing system.
If they are the same pipe in a straight line, they are likely for a clothesline.

 

[Erin Francey]

I vote clothesline also!

All of these guesses are better (less expensive) than my oil tank idea. I 'll let you know (I don't live near there so haven't seen it for myself).

They could be previous test holes. If there was an oil spill they would of been capped & opened to test & monitor soil condition.
