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.

Lovely. Just very lovely.

Enjoyed this peaceful, calming journey into a magnificent redwood forest and looking forward to revisiting soon…

The description of the trees is very good.

The overall narrative of the environment in and around the trees is awesome. It puts the listener right amongst the trees.

There was so much information to take in.

I voice of the story teller helped me to relax while learning more about the great red wood. This Sleeping World was a delightful find.

Majestic Old Growth Coastal Redwoods

I hope the author learns more words to describe these trees than to simply repeat their approximate age over and over again. I've seen these trees and expected more. Maybe an updated version describing the feeling when walking through the forest. Try not to repeat Two thousand, two hundred, so many times.....imho.

Perfect for falling asleep with

I liked the slightly accented cadence of the narrator. She is clear and soothing but it makes it more interesting so my attention does not wander. Love this whole series and glad there are new episodes.
