The things that I carry
When hiking, we carry touchstones to our existence. The predominate item is water. Water lubricates to sustain us. Thirst is powerful. A pint is a pound the world around. When you need a gallon a day, that is the first eight pounds on your back.
Only you may not need to carry the full eight pounds between start to finish. A water filtration system can extend the carry. But only if there is flowing or pounded water available to pull from. Puddled water is inadequate.
Hiking is generally to higher ground. Good water flows to lower ground. As such, filling up, topping off at lower ground is necessary to achieve higher ground.
Water is only one thing that I carry. But finding, seeking, carrying water makes all other things possible.
Then head for higher ground.
