15 excursions with a lot of shade

Source Summary

In the heart of July, the mountain can be a suffocating trap or an inscrutable oasis. The difference, basically, depends on a millennia-old technology that doesn't plug into anything: the tree. We all know the blast of heat when we open a car parked in the sun, and the sigh of relief when we find it under the protection of a good canopy. This same survival logic, scaled up, turns forests into the planet's most efficient primitive air conditioning.
