Some funny and weird black and white photos from the past.
In meteorology, a virga is rain falling from a cloud that evaporates before reaching the ground. At high altitudes the precipitation falls mainly as ice crystals before melting and finally evaporating. The phenomenon is very common in deserts, where low humidity and high temperatures can cause rain to evaporate shortly after being released by clouds. You might see virga in the U.S. West and above the Canadian Prairies, in the Middle East, Australia and North Africa.

Lake Kaindy is located in the south of Kazakhstan, within Kolsai Lakes National Park. The lake is about 400 meters long, reaching depths of nearly 30 meters at its deepest point. Altered by limestone deposits, the water maintains a bluish-green color.
The lake is well known for its scenery, particularly its trunks of submerged Picea schrenkiana trees that rise above the surface of the lake. The area is often referred to as a “sunken forest”. The cold water helps preserve the tree trunks, which are overgrown with algae and various other water plants. In recent years, Lake Kaindy has become a popular international tourist destination. It is considered a natural landmark of Kazakhstan. The lake is also known for ice diving and trout fishing in the winter season.

Dallol is a cone volcano in the Danakil Depression, northeast of the Erta Ale Range in Ethiopia. It has been formed by the intrusion of basaltic magma into salt deposits and subsequent hydro thermal activity. Eruptions took place in 1926, forming Dallol Volcano. Numerous other eruption craters dot the salt flats nearby. These craters are the lowest known sub aerial volcanic vents in the world, at 45 m (150 ft) or more below sea level. In October 2004 the shallow magma chamber beneath Dallol deflated and fed a magma intrusion southwards beneath the rift. Numerous hot springs are discharging brine and acidic liquid here. Small, widespread, temporary geysers produce cones of salt.
The term Dallol was coined by the Afar people and means dissolution or disintegration, describing a landscape of green acid ponds and iron oxide, sulfur and salt desert plains. The area resembles the hot springs areas of Yellowstone Park but it is much hotter and its waters are much more acidic.

During the winter, 56% of the Lake Michigan was frozen as temperatures reached negative 23 degrees Fahrenheit. As the frozen lake started melting, water underneath the ice pushed broken pieces of ice against one another and up to the surface transforming the region into a magical wonderland.
Chan Dan Ya – meaning in Mandarin ‘egg-producing cliff’ – is a 20 metres (65 feet) long and six meters (19 feet) high cliff. People of the area have observed for years as the eggs ‘incubate’ in hollow overhangs on the cliff and eventually fall to the ground. Each hollow produces one stone egg every 30 years. Local residents collect the spheres because they believe that the “eggs” would bring them good luck.
The rock formed 500 million years ago during the Cambrian period and the specific section of cliff – part of Mount Gandeng – is made of calcareous rock. Experts say the difference in time it takes for each type of rock to erode has led to the appearance of the “eggs” , which comprise heavy sediment deposits. The “eggs” are what geologists call concretions. If those concretions are harder than the rock around them (as they often are), they’ll eventually wear down the surrounding rock and break free.
