Vachellia is a genus of flowering plants in the legume family, Fabaceae, commonly known as thorn trees or acacias. It belongs to the subfamily Mimosoideae. Its species were considered members of genus Acacia until 2009. Vachellia can be distinguished from other acacias by its capitate inflorescences and spinescent stipules.
The members of Vachellia are trees or shrubs, sometimes climbing, and are always armed. Younger plants, especially, are armed with spines which are modified stipules, situated near the leaf bases.
Vachellia collinsii (also known as Acacia collinsii) is native to Central America and parts of Africa. It grows in secondary succession in seasonally dry ecosystems in southern Central America, with preferences to Savannah-like climate.
Vachellia collinsii can grow up to 40 feet tall. The tree grows relatively straight with thorns generously distributed across the branches.
It exhibits a symbiotic relationship with several species of ant (Pseudomyrmex spinicola, Pseudomyrmex ferruginea). The ant-Vachellia system involving this species has been studied by ecologists like Daniel Janzen in Palo Verde National Park and Santa Rosa National Park, both in Guanacaste Province, Costa Rica. The ants chew holes in the tips of the hollow stipular thorns, known as domatia, so that they can enter, and create their colony inside. A single ant colony may span several V. collinsii trees. Medium sized herbivores are deterred by the thorns but the ants help protect the trees from attack by other smaller or larger animals such as caterpillars and elephants. When a predator brushes and shakes the plant’s thorns in an attempt to feed, the ants will become disturbed and run outside and release alarm pheromones to alert other ants. All ants that come in contact with the volatile become aggressive and attack the animal by biting and stinging.

The mud pools and steam vents on the southwest part of Reykjanes close to Reykjanes lighthouse are collectively named Gunnuhver after a female ghost that was laid there. She had caused great disturbance until a priest set a trap for her and she fell into the spring. This happend about 400 years ago.
The mud pools form where steam from boiling geothermal resevoir water emanates and condenses and mixes with surface water. Accompanying gases such as carbon dioxide and hydrogen sulphide make the water acid. This causes alteration of the fresh lava rock to clay.
Two ramps are located at the Gunnuhver group, on close to Gunnuhver itself where you can look down to the spring and hear the vigorous noice, see the boiling water and feel lthe power bursting from the ground and the steam on your face. The other ramp is located on Kísilhól a silica hill. From there you have a good view over Gunnuhver group and suroundings.

This mud pool belongs to the volcano crater Solfatara, in Pozzuoli, near Naples in Italy. It is a dormant volcano which still emits jets of steam with sulfurous fumes.
Cette flaque de boue en ébullition est située dans le cratère du volcan Solfatare près de Naples en Italie. La Solfatare est un volcan dormant plat à sol de cendres et de soufre, dont l'activité postvolcanique est constituée principalement de fumerolles.

South of the Krafla area, but not actually within the caldera is Námafjall, a mountain, beneath which is Hverir, a geothermal area with boiling mudpools and steaming fumaroles
Probably the best know image from the oldest National Park. As first time visitors it was of course one of the musts. Most of the spectators (some hundreds for each eruption) are seated on the benches at the other side. That where we were for our first eruption. I took maybe 30 shots from that side but none of them seem to do justice to the experience.
At the time of the second eruption during our visit I used the Anemone geyser as a foreground for the big one.
Walking between the geysers and boiling mudpools is an experience for many senses: not only spectacular to see, these things make sounds, spread their smells and will make you wet.
The Old Faithful is known for his regularity and of course the heighth that he reaches: about 50 m high which is higher than most church towers in Europe.

Mudblubs in the Wai-o-tapu Scenic Reserve in New Zealand. It is hot gases exploding through wet mud with satisfying plopping sounds. The erupting mud in the mud pool was taken with a Nikon D200 and converted to B&W.
Uzon caldera (9 x 12km) was formed about 40000 years ago following a series of eruptions of a volcano. It is now a stunning landscape (particularly against the back drop of Autumn colours) dotted with geothermal activity such as this boiling mud pool.

We took the car to Okere falls, a lush forest area with plenty of
waterfalls and caves to see. There was also an old hydro generator
from the early 20th century on display. We walked around for around an
hour. Back at the hostel, I raised an eyebrow when Emma told me about
a place called Hell's gate. The Maori call it "Tikitere". It's
Rotorua's most active geothermal area on State Highway 30, between
Lake Rotorua and Lake Rotoiti in the Bay of Plenty, New Zealand. It
includes many geothermal features including steaming lakes, mudpools,
fumaroles, a mud volcano and Kakahi, the largest hot waterfall in the
Southern Hemisphere. It was something else! Like a moon landscape.

After, we went to "Wakarewarewa" living thermal village, where Maori
people still live as a tribe. We took the guided tour through the
village by one of the villagers. She greeted us with 'Kia Ora', which
means 'Good health to you.' Guiding tourists is something they've been
doing for hundreds of years. They still cook most of their food in
self-made pressure cookers, which are simply wooden boxes placed on a
thermal exit from the ground. It will steam-cook just about everything
and taste wonderfull. Nothing will burn in there. In the picture, you
see our guide next to the boiling pool of water where they boil food.
It runs 30m deep! She showed us the communal bathing place, burriel
grounds and some geysers that become active once every hour for about
15 minutes and spray boiling water up to 10m up in the air. She
mentioned that only 10% of active geysers remain today, compared to
1930. That's because surrounding accomodations tap into the power to
offer geyser-heated baths to tourists, right into their rooms - as a
gimmick. When I asked her, she told me that they haven't stopped
tapping the power up to this day.
Next up: Taupo! Just a 80km drive south from Rotorua.

Volcanic mud pools near the Rincon de la Vieja volcano.
Mudpools form in places where thermal fluids have chemically decomposed surface rocks to form clay. This clay is heated by the underground energy source and boiling mud pools are created. Activity tends to vary from season to season, depending on the varying amounts of rain to moisten or dry the mud. Accordingly, mud pools generally appear more active in winter than summer.
At the foothills of this spectacular volcanic mountain is an expanse of hot springs called Hveraröndor Hverir that are known for their changing variety. You may also find a number of fumaroles, mud pools and mud pots that all seem to be boiling with relentless energy. The pass Námaskarð is strategically located at a short distance from the Krafla volcano system as well as other interesting geological spots like Búrfellshraun and the desert Mývatsöræfi.
Námaskarð earns its notoriety chiefly because of its sulphurous mud springs called solfataras and steam springs called fumaroles. Though you will scarcely find any pure water spring in this wonderful geothermal site of Iceland, the beauty of the colorful minerals defies all comparisons. The gigantic size of the mud craters is what makes you go ‘wow’ at the sight of them.
The other thing that is sure to strike you about Námaskarð is the sheer lack of vegetation. However, if you give a thought to the high temperature range, it does not appear an impossibility altogether. The constant emission of the fumes has made the ground utterly sterile and acidic, unfit to sustain any floras and faunas. You must bear in mind that the fumes can be harmful for humans as well.

It's hot down there ... very, very hot.
I did some research and chose to visit the Wai-O-Tapu thermal area near Rotorua. Parts of this thermal area were truly spectacular, particularly the Artist palette and Champagne pool.

Perhaps it was the fact that we were closer to Reykjavik so shared the place with many other tourists, but the mud pools at Myvatn seemed to be more interesting. And were larger. Still once you were looking down on them, you got a good view. Despite the fact that they just made me want to burp all the time.
