L2 - I love your enthusiasm. Re your note on the way pumps and equipment can't function....note that the cloud point of a diesel fuel can normally only be lowered by the addition of a product with a lower wax content e.g. Heating Oil and similar products.
However by using additives called cold flow improvers it is possible to lower the temperature at which the wax crystals will block filters (the Cold Filter Plugging Point or CFPP) and the temperature at which the diesel freezes (Pour point). These additives work by changing the size and shape of the wax crystals. I'm quite sure copious quantities of the cold flow improver additives would have been consumed in maintaining the function of running pumps etc. More likely they had run out of diesel and could not get supplies up the mountains in the impossible snow drifts!
