Is water easily available in the backcountry?
It depends on region and season. There are a few desert or desert-like areas in the southeast and northeast where finding water is difficult. The backcountry actually means the mountains and in the mountains there’s usually some water but consider a few hints: the atlantic regions are damp, running water is usually available year round. The highest mountains have also year round water even if they go through a dry season because of the melt off. There are some limestone areas where all water filters underground so it may be difficult to find even in damp regions/seasons. In general, the more to the south, the drier the weather and the less surface water available.
