Caves keep visitors cool in extreme heat

LAKEHEAD, Calif. -

There are a lot of ways to avoid extreme heat - but one many overlook is going underground.

Lake Shasta Caverns, on the shores of Lake Shasta, stays at a constant 58 degrees year round, making it a perfect example of natural air conditioning.

When the door opens, the blast of air welcomes you out of the triple digit heat and into a world of stalactites and stalagmites.

The cave’s temperature is maintained by the rocks it’s carved into.

The temperature is determined by the area’s yearly average temperature, and the rocks insulate it against both the extreme heat of the summer, and the cold of winter. 

If there is a down side to the boat ride, exploration, and natural air conditioning it’s coming back out into the heat at the end of the tour.
