Propane freezes long before -60C.
The recent cold snap in the Yukon had smaller tanks useless just past -35c, and bigger ones not doing much past -40c.
We don’t take it on winter adventures for that reason.

Propane does not freeze anywhere near -60C. Wikipedia [1] says it freezes (liquid to solid) below -187C and boils (liquid to gas) above -42C.
Propane is probably unusable as a fuel below -42C because there is no vapor leaving the tank [not within my experience]. That is different from the propane being a solid.

Ask anyone that lives in Yukon/Alaska. They’ll tell you.
