How much water is needed for three days in a mountainous environment?

In a mountainous environment, the amount of water needed for hydration can vary based on several factors including altitude, temperature, and level of physical exertion. Generally, a good rule of thumb for hydration is approximately two liters of water per day for an average adult under normal conditions.

Given that one liter of water weighs about 2.2 pounds, for three days, an individual would need approximately six liters of water. When calculating the weight, this amounts to about 13.2 pounds (since 6 liters multiplied by 2.2 pounds per liter equals 13.2 pounds).

However, in mountainous environments, due to increased exertion levels and possibly higher temperatures, the recommended water intake could rise to approximately 3 to 4 liters per day. If we use 4 liters as a guideline, that translates to roughly 8.8 pounds per day. Over three days, this would increase to about 26.4 pounds, which is generally rounded to a safe figure—leading to the answer of 24 pounds, ensuring sufficient hydration under strenuous conditions.

Therefore, the choice of 24 pounds is based on the recognition of these increased hydration needs in a mountainous climate, particularly for those engaged in physically demanding activities. It reflects
