How does one do Hagalah above 12,000 feet, where water's boiling point falls below 190°F? Under normal circumstances, the water will not be Rochsim, and therefore unsuitable for Hagalah.

Using a pressure cooker would be impractical, as it cannot be opened to put an item in. (Besides, the water would not reach an actual boil – safely. Furthermore, at higher altitudes, even a standard pressure cooker cannot keep water's boiling point above 190°F.) Leaving the item on a platform while the water heats, later to be shaken down, would present a problem of steam in an enclosed space.

Would one have to forgo Hagalah altogether, and default to Libun Kal?

@GershonGold That is linked to already in the question – Double AA Feb 6 '14 at 18:24
How is this not just a duplicate of that linked question?? – Double AA Feb 6 '14 at 18:24
@DoubleAA Because a valid answer there applies only to locations below 12,000'. I am asking about above that. – Adám Feb 7 '14 at 15:12
@NBZ That's just not true. The question makes no such requirement. – Double AA Feb 7 '14 at 15:29

Mishna Berura Orach Chaim 452:8 would allow B'Dieved if it is not used as a Kli Rishon to do Hagala without Rochsin. However with a Kli Rishon there seems to be no option if it is not Rochsin.

No option (for hagalah), i.e. libun kal necessary. Maybe you should put that into your answer? – Adám Feb 7 '14 at 15:13
