Mud-puddling is the phenomenon mostly seen in butterflies and involves their aggregation on substrates like wet soil, dung and carrion to obtain nutrients such as salts and amino acids.
Lepidoptera (butterflies and moths) are diverse in their strategies to gather liquid nutrients. Typically, mud-puddling behavior takes place on wet soil. But even sweat on human skin may be attractive to butterflies. The most unusual sources include blood and tears.
This behaviour is restricted to males in many species. Males seem to benefit from the sodium uptake through mud-puddling behaviour with an increase in reproductive success. The collected sodium and amino acids are often transferred to the female with the spermatophore during mating as a nuptial gift. This nutrition also enhances the survival rate of the eggs.
Lots of bears out and about in Cades Cove right now feeding on acorns and fattening up for Winter. This one was enjoying a mud bath in a watering hole.

I never saw boiling mud before. It moves in slow motion, an intricate restless dance...most of its moves will never be seen.
This was great fun to capture, holding my breath from the plumes of toxic smelling smog and trying to keep my lens from steaming up! Timing was everything as the shapes of the splatters changed so drastically every split second the steam would at times cloud over the mud pot completely!

This is an image of the mud men tribe from Papua New Guinea. The legend goes that many years ago these men where running from their enemy who was trying to kill them. As they ran down a hill they all fell into a huge mud pit. When they climbed got out of the mud they were covered from head to toe. As their enemy came over the hill and saw them they thought they were ghosts and they ran away. After that experience the tribe decided to keep the mud on and add the mask. They were one of my favorite tribes!
Even this old door lock was still coated in dry mud that has been leftover from the Great Brisbane Flood of early 2011

On November 26, 2010, Pakistani fishermen returned from a day at sea to report that a new island had emerged. The tiny dot of land was a mud volcano, and it was still visible on January 11, 2011, when the Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite acquired the top image. The mud volcano was absent in a previous overpass on February 11, 2010, shown in the lower image.
There’s no need to change any maps, however; mud volcanoes have risen off the coast of Pakistan in the past and disappeared again within a few months, washed away by the waves and currents in the Arabian Sea. It is quite likely that this new volcano will meet the same fate. Indeed, a stream of pale brown sediment was snaking away from the volcano to the west on January 11, suggesting that erosion was already underway.
Pakistan’s mud volcanoes form as a result of plate tectonic activity. The Arabian plate—the section of Earth’s crust that carries the Arabian Sea—is sinking beneath the Eurasian land mass at about four centimeters per year. Some of the thick sediment and rock on top of the Arabian plate has sloughed onto the edge of the Eurasian plate, forming Pakistan’s coastal plain, the Makran Desert, and the underwater slope leading away from the shore. It is from this sloughed-off land that the mud volcanoes form.
Beneath the sediment, along the accretionary front, the sinking Arabian plate heats up under extreme pressure and rock melts into magma. Volcanic gases and magma heat the groundwater, turning it in a hot acid that dissolves rock into a slurry of mud and clay. The mud and gas seep through faults, eventually erupting at the surface as a mud volcano.
Pakistan has a number of mud volcanoes in the Makran Desert and offshore. According to the U.S. Geological Survey, mud volcanoes are usually less than 1-2 meters (3-7 feet) tall. But Pakistan’s Chandragup Complex includes a mud volcano that is 100 meters (330 feet) high.
The same tectonic activity and fault systems that produce these volcanoes occasionally produce large earthquakes, such as the magnitude 7.2 quake that shook southwest Pakistan on January 18, 2011.

The weather station 2 miles from my house said 39ºF. I guess it got a little colder after I got to the lake this morning. The mud holes started freezing up while I was there.
5 days ago it was in the single digits. Yesterday, I was walking around the lake before sunrise in a t-shirt — in the mist and wind to boot. Today it’s back below freezing. Winter in Georgia.
