Kind: research · Impact: low

## In brief

- The twelve water spigots used by visitors in Grand Canyon National Park have drawn their water from Roaring Springs, a cave-fed spring on the North Rim, for decades.
- An August 2025 study by researchers at Northern Arizona University (NAU) described over 6 miles of caves connected to the spring.

## Why it matters

It identifies the single cave-fed source behind the park's visitor drinking water, which is relevant to how the park's water supply is understood and protected.
