Ribbon Fall is a plunge-type waterfall located in Yosemite National Park, California, United States. The waterfall descends a sheer cliff on the western side of the Yosemite Valley, directly opposite Yosemite Falls. Its total drop is approximately 1,612 feet (491 meters), making it one of the tallest waterfalls in the world.
Geography and Hydrology
- Location: The fall is situated within the Sierra Nevada mountain range, roughly midway between the Merced River and the main trail to Yosemite Falls.
- Source: Ribbon Fall is fed primarily by snowmelt and seasonal precipitation that collects on the granite slopes above the cliff. Because its flow depends on meltwater, the waterfall typically runs at its greatest volume in late spring (May to early June) and may be reduced to a thin trickle or completely dry during late summer and fall.
Physical Characteristics
- Height: 1,612 feet (491 m), measured from the lip of the cliff to the base of the plunge pool.
- Type: Plunge waterfall; the water loses contact with the rock surface during its descent.
- Seasonality: Highly seasonal; peak flow occurs during spring melt, with minimal or no flow in the drier months.
Historical and Cultural Context
- The name “Ribbon Fall” derives from the thin, ribbon-like appearance of the water as it falls in a narrow, uninterrupted sheet.
- The waterfall was documented by early park naturalists and appears in photographs and maps dating to the late 19th and early 20th centuries. It has been a subject of interest for geologists studying the erosion of granite cliffs in the Sierra Nevada.
Conservation and Access
- Ribbon Fall lies within the protected boundaries of Yosemite National Park, which is managed by the National Park Service. The area is subject to federal regulations aimed at preserving natural features and ecosystems.
- The base of the fall is accessible via hiking trails that circumnavigate the valley floor, though no official viewing platform is dedicated specifically to Ribbon Fall.
