The Sleeping World: Listening to the Forest with an Ancient Redwood

By: Mumble Media, Audible Sleep

Narrated by: Cynthia Kimola

Wind down by escaping into nature. Part soundscape and part bedtime story, The Sleeping World is an intimate journey through ecologies around the world.

California’s coast redwoods are Earth's tallest living beings, some reaching more than 350 feet high. They can also live for more than 2,000 years, outlasting entire civilizations. In this episode, we spend an evening with an ancient tree. Below ground, its roots tap into a forest-wide network; above ground, its branches harbor life in its many forms.

This is the world in its natural state, defined by seasons, routines, and cycles. By the time the stars have come out above the misty canopy, you’ll be ready to rest.
