Travertine is a form of limestone deposited by mineral springs, especially hot springs. Travertine often has a fibrous or concentric appearance and exists in white, tan, cream-colored, and even rusty varieties. A travertine terrace is formed when geothermally heated alkaline waters emerge to the surface and form waterfalls of precipitated carbonates.

Moraine Lake is a glacially fed lake in Banff National Park, in Alberta, Canada. The lake, being glacially fed, does not reach its crest until mid to late June. When it is full, it reflects a distinctive shade of blue. The color is due to the refraction of light off the rock flour deposited in the lake on a continual basis.
The area around the lake has several walking/hiking trails. That view of the mountains behind the lake in Valley of the Ten Peaks is known as the “Twenty Dollar View”, as Moraine Lake was featured on the reverse side of the 1969 and 1979 issues of the Canadian twenty dollar bill.

A dust devil in Arizona – By NASA (NASA web page & source file) [Public domain], via Wikimedia Commons
A dust devil is a strong relatively long-lived whirlwind, ranging from half a meter wide and a few meters tall to more than 10 meters wide and more than 1000 meters tall. Dust devils are usually harmless, but can on rare occasions grow large enough to pose a threat to both people and property. Dust devils form when hot air near the surface rises quickly through a small pocket of cooler, low-pressure air above it. A fully formed dust devil is a funnel-like chimney through which hot air moves, both upwards and in a circle. As the hot air rises, it cools, loses its buoyancy and eventually ceases to rise.

A series of paintings of urban weeds by San Francisco-based artist Mona Caron. Her focus is on community-informed and site-specific murals in public space. She has created large-scale murals in the US, Europe, South America and Asia, has delved into stop-motion animation as part of her “WEEDS” project.
In her own words:
I paint all kinds of spontaneous urban vegetation: both invasive and endemic species. Both get eradicated as weeds when they get caught trespassing our enclosures. Yet they come back, always at the front lines, carving a path for the rest of nature to follow.
Weeds break through even the hardest cement, the most seemingly invincible constraints, reconnecting earth to sky, like life to its dreams. It’s happening everywhere at the margins of things, we’re just not paying attention

Grüner See (Green Lake) is a lake in Styria, Austria, surrounded by the Hochschwab Mountains and forests. The name “Green Lake” originated because of its emerald-green water. During winter, the lake is only 1–2 m (3–7 ft) deep and the surrounding area is used as a county park. However, in spring, when the temperature rises and snow melts, the basin of land below the mountains fills with water. The lake reaches its maximum depth of around 12 m (39 ft). The waters are at their highest in June when it becomes a destination for divers keen to explore the rare phenomenon. A bridge and a bench could also be found underwater, as well as trails and trees.
