Drift into deep sleep with a calming nature documentary that explores how glacial erosion carved Yosemite Valley into the iconic landscape we see today. With soft narration and gentle natural ambience, we follow ancient ice as it moves through the Sierra Nevada, shaping granite cliffs, polished rock, and the wide U shaped valley floor.

Perfect for bedtime, relaxation, stress relief, or quiet background viewing, this geography focused sleep documentary invites you to unwind while discovering the forces that sculpt Earth’s most breathtaking national parks.
