Travertine Dams

Travertine Dams
Havasu Creek, Grand Canyon, Arizona, USA. The water is saturated with calcium carbonate, which precipitates as travertine (a freshwater limestone) when agitated. This builds up these curious structures. Colloidal CaCO3 is also responsible for the curious turquoise color to the water.

It's a somewhat similar phenomenon; you're precipitating calcite from saturated water! But what happens is that CO2 outgasses in the agitated water, which triggers the precipitation.

Anywhere you've got thru-flowing water in limestone bedrock you're likely to get this phenomenon.
