The secret underground system keeping the Grand Canyon alive

Scientists are venturing into the Grand Canyon’s hidden cave networks to solve a mystery: how snowmelt travels underground to supply the park’s vital springs. Their discoveries could help protect the canyon’s water from drought, contamination, and other growing threats.

Many years ago I spent a week hiking from south to north rim and back. I did wonder if there were caves in some of the limestone layers but didn't spot anything obvious. My main problem wasn't drought and extreme heat but snow and freezing temperatures, especially on the north rim which was quite a bit higher than the south (it was December). Down by the river about a mile lower in altitude it was very pleasant.

Often wondered how the snowmelt got to the bottom!!!
