Icylic GLYCO BREATH refers to the soil in a permafrost up to two meters deep. Sounds strange, but not impossible. It is actually a spelling mistake by icy (and not gelid) but also the adjective must have been, apparently, GÉLIDO h to point out an icy breath, very cold as in Puccini's Oper La Boheme : Che gelida manina (What a colder hand).
