My darling little nieces aged 8 and 10, including my spunky godchild - i'll let you guess which one of the two she is- are seasoned travellers. They have been to every single major continent and great little spots like the Galapagos and the Caribbean. At their current pace, they are going to catch up with me real fast on number of countries visited. I better get back out there fast!
Mono Lake, California, 1982 Photograph by James P. Blair
"Spires of limestone tufa rise from the shores of California’s Mono Lake. Tufa form when underwater springs rich in calcium meet lake water rich in carbonates, forming calcium carbonate, or limestone. The limestone precipitates in layers over time and can grow more than 30 feet (9 meters) high. Mono Lake’s tufa are particularly dramatic because water diversions have significantly lowered the lake’s level, exposing more of the columns.
