Link to the revision I am talking about

In section 1, "In the United States," it is said:

The pogonip fog is so thick you can't even see your hand. Go out in it and you'll be lost in seconds. If it lingers you'll die of starvation or exposure. Breathing pogonip can damage your lungs thus the term white death. [citation needed]

In section 2, "In Siberia", it however is said:

The city of Yakutsk is famous for its ice fogs. The water vapour in the air freezes when there's no wind and produces a thick ice fog. When a person walks through this fog, behind him or her a completely visible tunnel appears, and children going to school often play a game trying to guess who has just passed (here our fat schoolmate, there that tall teacher...)

So ice fog is a deadly nightmare of icy doom — unless when it is not, and then children play with it? —Preceding unsigned comment added by Badpazzword (talk • contribs) 18:57, 14 December 2009 (UTC)[reply]

I've lived with pogonip. Where I lived in Nevada, sometimes temps would hover at negative 13:21, 23 May 2012 (UTC) 40 degrees F for a week straight. Pogonip's not just scary, it can be dangerous to go out into, because many times you can't see more than a foot: You can stumble into something unfortunate, freeze, get lost and starve, or die of thirst. 71.22.155.114 (talk) 20:19, 29 April 2012 (UTC)[reply]

Visible tunnels

I removed this text:

The water vapour in the air freezes when there's no wind and produces a thick ice fog. When a person walks through this fog, behind him or her a completely visible tunnel appears, and children going to school often play a game trying to guess who has just passed (here our fat schoolmate, there that tall teacher...) (Source: "-46°" (in Italian). Retrieved 2009-02-14.)

The source is a blog, which does not seem very reliable, and the phenomenon described is aerodynamically improbable. -- Beland (talk) 02:38, 28 February 2010 (UTC)[reply]

Temperatures?

"It can happen only in cold areas of the world since water can remain liquid down to -40 °C (-40 °F)."

Which temperature is wrong? Celsius and Fahrenheit are not the same thing... I'd assume -40°C is the correct temperature. -40°F seems too cold. Jacksonalv (talk) 14:51, 13 August 2010 (UTC)[reply]

Actually, they are the same. 86.89.144.60 (talk) 09:18, 6 December 2010 (UTC)[reply]

Direct to ice?

The Diamond dust article says "the term ice fog usually refers to a fog that formed as liquid water and then froze". This article says "Pogonip only forms under specific conditions, [...], allowing ice crystals to form in the air". I believe that the later is misleading and should read "Pogonip only forms under specific conditions, [...], allowing water droplets to form in the air, which subsequently freeze into ice crystals". 86.89.144.60 (talk) 09:18, 6 December 2010 (UTC)[reply]

Pogonip: Ice Fog or Freezing Fog?

It seems to me that common usage of the term "pogonip" refers more to what is known as "freezing fog" rather than "ice fog". Ice fog is described on this page as forming at temperatures near -40F, and that is hard to reconcile with the word being Shoshonean, since they rarely if ever would have encountered those conditions. I recall (as a teenager) the news media in Reno, Nevada using the word "pogonip" to describe "icy fog" conditions when the temperature certainly did not drop below +20F. Here's a link to a January 2011 media web page predicting pogonip in Nevada's Douglas County in early 2011: http://www.recordcourier.com/article/20110105/NEWS/110109944/1062&ParentProfile=1049 — Preceding unsigned comment added by Gac1959 (talk • contribs) 10:57, 7 January 2011 (UTC)[reply]
