Water in winter on dry, snowless trail?

I am hoping to do at least some of the Knobstone Trail in southern IN this winter. It's known to be a pretty dry trail except during rainy periods, and we generally don't have enough snow to melt here. People normally cache their water, but it would freeze by the time you got to it.

Would you just carry all you need for 3-4 days? Cache in smaller bottles you can cut open to set into your pot?
