About eight miles down the North Kaibab Trail from the Grand Canyon's North Rim, a short detour off to the right beckons sun-parched backpackers to
How did this colossal structure form? Water from the falls makes a 120 foot free-fall landing precisely at the apex of the moss-covered travertine dome. Calcium carbonate is in solution, being made soluble by the absorption of atmospheric carbon dioxide, which makes the water mildly acidic. Its acidity allows the carbonate to be “acquired” from limestone formations at higher elevations such as the Redwall and Muav. Subsequently, carbonate is “released” from the mineral-rich dripping water when it plunges over the falls and releases the carbon dioxide held in solution. The change in water chemistry causes the re-deposition of the carbonate in the form of travertine or tufa (softer and more porous) from the mineral-laden water. Gradually, the mound grows by re-crystallization, molecule by molecule. This landform is called karst, made possible by the dissolution of soluble bedrock. The identical process forms the more familiar stalagmites and stalactites in subterranean limestone-caverns.
This view is taken from behind the falls, looking out at the top of its verdant, mossy travertine dome. Vegetation such as the moss, and golden columbine, maidenhair fern and scarlet monkeyflower thrives in the oasis of the fall’s unique microclimate. These plants are not indigenous to the hot, arid climate of the Grand Canyon only a few feet away .
Ahh So nice! Makes me want to return there. Good shots.
