[edit] Contradiction
"Dry, moist soil at certain temperatures is most susceptible to frost heaving." Dry *and* moist? TotoBaggins
[edit] Seasonal timing
It might be useful to add some info about when this commonly happens.
Is it in the Fall, when ground starts to freeze? During the coldest part of Winter, when more ground freezes? In the Spring, when ground thaws during the day and re-freezes at night? Or allo f these times? T-bonham 02:08, 3 February 2007 (UTC)
[edit] Frost creep merge suggestion
I'm not a geologist, but that article suggests that "frost heave" is synonymous, and given that it'd seem more sensible to make that article a redirect to this one. --Joe Decker 00:34, 12 February 2007 (UTC)
Yeah, I agree, frost creep should become a section of frost heave. I am also not a geologist, but I think they would have no problem with that subject being covered under one article. Dragonbeast 18:32, 28 February 2007 (UTC)
Sorry to disagree all, but I am a Structural Engineer and would have some points to be addressed were the two articles to be merged. Frost creep involves movement, and although is effected by similar actions, is not the same as Frost heave. In effect frost creep is caused by frost heave. All that being said, I would not have a problem with frost creep being a section of frost heave, so long as the explanation regarding creep be retained. The statement that the two are synonymous should in any case be removed (I'll go do that now). - 5 April 2007 (1:09 am)
[edit] frost heave in desert
In "Sandy deserts of Iceland: an overview" O. Arnaldsa, F. O. Gisladottirb and H. Sigurjonsson seem to describe rocks being lifted in Islandic sandy deserts through frost heave. I can't get at the full article, but remember a similar one a while back. Could s.o. with expert knowledge plse. confirm. That would mean the text about "moist" soil would need to be changed.Lisa4edit (talk) 16:45, 27 April 2008 (UTC)
I've just taken a look at that paper and here's a snippet from the Implications/conclusions section.
"The sandy deserts lack waterholding capacity and the black surfaces become warm and dry on sunny days. Water shortage therefore impedes plant growth, which gives Icelandic deserts similar properties to the arid deserts of the world, in spite of the more moist climate in Iceland."
So they are dry and don't hold water well... but earlier in the paper it mentions that the area can be flooded... So I'm guessing that it's moist enough to allow frost heave ... it's just that the surface is far too dry to allow plants to take hold... but at the sand is ontop of a Till and so there could be water down there... Sorry no time to make a coherent, wellspelled or formatted comment... I've got an exam on Cold Climate Geomorphology in 25 mins... ARGH!
