Crystal Peak
At the north end of the Wah Wah Mountains in western Utah. It's composed entirely of the Tunnel Spring Tuff of early Tertiary age. Cavernous weathering is prominent! For scale the larger bushes are full-sized Utah junipers.

slgwv club has replied to Andy Rodker clubA tufa, OTOH, is a freshwater limestone, commonly deposited around calcium-rich springs, but they can also be deposited by wave action along the shores of freshwater lakes high in dissolved calcium. (What happens is that CO2 exsolves from the agitated water, which causes precipitation of calcium carbonate.) Both types are common in my area and are associated with Pleistocene Lake Lahontan. Here are some tufa "towers," deposited from springs:

and here are some shoreline tufas (plus my Jeep's aerial!) near Pyramid Lake, on the eponymous reservation:

The rock that _is_ basically the same as tufa is travertine, also a freshwater limestone. That term is commonly used for deposits in streams, but it's also used for springs, and the distinction gets a bit arbitrary (and historical!)
