Today was exceptionally beautiful. The weather was well-nigh perfect. And it was Saturday. Went to where I store the bike and first order of business was to re-grease the clutch bucking bar, a small cylinder which is used to engage the clutch, because there's a little squeaking sound when I push the bike and I don't like that. haha. Then re-tighten the head bolts, the motor mounts, the carb float bowl screws and the exhaust and intake port nuts. Takes all of 3 minutes. Topped off the tank with my hand-mixed gas/oil solution.
Pedaled a few feet, popped the clutch and she started right up. Sounding great. Then up the hill...up up up, climbing. Still there are a couple of places on the back side of Yang Ming Shan that require a few pumps on the pedals, usually if it bogs down to 14 mph, which is seldom.
On up through the park and then up the main drag to Xiao You Keng. This is a large fumarole on the northwest side of Seven Star Mountain (七星山). Smoulding sulphurous steam clouds swirl continuously. This is also the crest where one can descend to the northern coast.
I decided to take an alternative ride on another crest (goo.gl/maps/QBs1o) which leads down to Danshui...but only went a short before turning around and going back down so I could take some nice shots of Xiao You Keng in the superb late-afternoon light.
The bike continues to run exceptionally well. I usually push it WOT (wide open throttle) on all the steep grades. It doesn't care.
I've not put a single cent into this bike in months and months. There's no maintenance other than tightening the bolts once in a while, and optionally greasing the bucking bar. No filters to change. No oil to change. The drive chain which caused me so much grief in the beginning has remain perfectly adjusted after hundreds of miles.
I am very thankful to have had this wonderful day riding on my China Girl in perfect weather in the outstandingly beautiful mountains of Yang Ming Shan!

The geothermal areas of Yellowstone include several geyser basins in Yellowstone National Park as well as other geothermal features such as hot springs, mud pots, and fumaroles. The number of thermal features in Yellowstone is estimated at 10,000. A study that was completed in 2011 found that a total of 1,283 geysers have erupted in Yellowstone, 465 of which are active during an average year. These are distributed among nine geyser basins, with a few geysers found in smaller thermal areas throughout the Park. The number of geysers in each geyser basin are as follows: Upper Geyser Basin (410), Midway Geyser Basin (59), Lower Geyser Basin (283), Norris Geyser Basin (193), West Thumb Geyser Basin (84), Gibbon Geyser Basin (24), Lone Star Geyser Basin (21), Shoshone Geyser Basin (107), Heart Lake Geyser Basin (69), other areas (33). Although famous large geysers like Old Faithful are part of the total, most of Yellowstone's geysers are small, erupting to only a foot or two. The hydrothermal system that supplies the geysers with hot water sits within an ancient active caldera. Many of the thermal features in Yellowstone build up sinter, geyserite, or travertine deposits around and within them.

West Pyrite Pool and the Big Boiler dominate the view here.
From americansouthwest.net, "The acidic, greyish water drains via several run-off channels across the colorful earth, combining with the discharge from other pools to form Bumpass Creek, which flows southwards out of the basin. The steaming vent to the right is Big Boiler, a very active fumarole."
Geothermal fumaroles in the Námaskarð geothermal field in Mýyvatn Area in North Iceland.
"A fumarole (Latin fumus, smoke) is an opening in Earth's (or any other astronomical body's) crust, often in the neighborhood of volcanoes, which emits steam and gases such as carbon dioxide, sulfur dioxide, hydrochloric acid, and hydrogen sulfide. The name solfatara, from the Italian solfo, sulfur (via the Sicilian dialect), is given to fumaroles that emit sulfurous gases.
Fumaroles may occur along tiny cracks or long fissures, in chaotic clusters or fields, and on the surfaces of lava flows and thick deposits of pyroclastic flows. A fumarole field is an area of thermal springs and gas vents where magma or hot igneous rocks at shallow depth are releasing gases or interacting with groundwater. From the perspective of groundwater, fumaroles could be described as a hot spring that boils off all its water before the water reaches the surface."

Geothermal areas of Yellowstone
The geothermal areas of Yellowstone include several geyser basins in Yellowstone National Park as well as other geothermal features such as hot springs, mud pots and fumaroles. In total, the number of thermal features in Yellowstone is estimated at 10,000 and 200 to 250 geysers erupt in Yellowstone each year, making it the the place with the highest concentration of active geysers in the world.[2] Many of these features build up sinter, geyserite or travertine deposits around and within them.
The various geyser basins are located where rainwater and snowmelt can easily percolate into the ground, get indirectly superheated by the underlying Yellowstone hotspot, and then easily erupt at the surface as geysers, hot springs, and fumaroles. Thus flat-bottomed valleys between ancient lava flows and glacial moraines are where most of the large geothermal areas are located. Smaller geothermal areas can be found where fault lines reach the surface, in places along the circular fracture zone around the caldera and at the base of slopes that collect excess groundwater. Due to high elevation of the Yellowstone Plateau, the average boiling temperature at Yellowstone's geyser basins is 199 °F (93 °C). When properly confined and close to the surface it can periodically release some of the built-up pressure in eruptions of hot water and steam that can reach up to 390 feet (120 m) into the air (see Steamboat Geyser, the world’s tallest geyser). Water erupting from Yellowstone's geysers is superheated above that boiling point to an average of 204 °F (95.5 °C) as it leaves the vent. The water cools significantly while airborne and is no longer scalding hot by the time it strikes the ground, nearby boardwalks, or even spectators. However, because of the high temperatures of the water in the features, it is important that spectators remain on the boardwalks and designated trails. Several deaths have occurred in the park as a result of falls into hot springs.
Prehistoric Native American artifacts has been found at Mammoth Hot Springs and other geothermal areas in Yellowstone. Some accounts state that they used hot water from the geothermal features for bathing and cooking. In the 19th century, Father Pierre-Jean De Smet reported that natives he interviewed thought that geyser eruptions were "the result of combat between the infernal spirits." The Lewis and Clark Expedition traveled north of the Yellowstone area in 1806. Local natives that they came upon seldom dared to enter what we now know is the caldera because of frequent loud noises that sounded like thunder and the belief that the spirits that possessed the area did not like human intrusion into their realm. The first Caucasian known to travel into the caldera and see the geothermal features was John Colter, who had left the Lewis and Clarke Expedition. He described what he saw as "hot spring brimstone." Beaver trapper Joseph Meek recounted in 1830 that the steam rising from the various geyser basins reminded him of smoke coming from industrial stacks on a cold winter morning in Pittsburgh, Pennsylvania. In the 1850s, famed trapper Jim Bridger called it "the place where Hell bubbled up."

Following our hike up to the Cliff Dwellings, we drove a bit further east on Arizona SR 260 and turned down Fossil Creek Road to visit a place locals call the Tee Pee Rocks, conical formations that are pockmarked with cavernous openings.
The unusual formations are called fumaroles. They were the result of hot volcanic ash falling on a surface that was saturated with calcium rich water, such as the shores of the former "Lake Verde." The water in the ground turned to steam and vented upward through the fallen ash.
Where the calcified water came in contact with the ash a layer of cement-like material was formed. Over time, the softer ash around the vents was eroded, leaving the conical shaped vent pipes exposed. (12-01-25-1277)
A mudpot, mud pool or paint pot is a sort of hot spring or fumarole consisting of a pool of usually bubbling mud.
Mudpots form in high-temperature geothermal areas where water is in short supply. The little water that is available rises to the surface at a spot where the soil is rich in volcanic ash, clay and other fine particulates. The thickness of the mud usually changes along with seasonal changes in the water table.
The mud takes the form of a viscous, often bubbling, slurry. As the boiling mud is often squirted over the brims of the mudpot, a sort of mini-volcano of mud starts to build up, sometimes reaching heights of 3-5 feet. Although mudpots are often called "mud volcanoes", true mud volcanoes are very different in nature.
The mud is generally of white to greyish color, but is sometimes stained with reddish or pink spots from iron compounds. When the slurry is particularly colorful, the feature is then called a "paint pot".

It's a geothermal area near a Krafla volcano. Steam coming from these fumaroles is rich on sulphur and quite stinks (but you'll get used to it soon).
There is really hot water splashing from the fumaroles, so we made lunch on this one. We boiled the eggs. Have a look at this video recoreded by our tour-chief Roman.

Valles Caldera National Preserve, New Mexico
Valles Caldera is a 13.7-mile (22 km.) wide volcanic caldera in the Jemez Mountains of northern New Mexico. Hot springs, streams, fumaroles, natural gas seeps and volcanic domes dot the caldera floor landscape.
It lies within the The Jemez Volcanic Field, above the intersection of the Rio Grande Rift, (Rio Grande Gorge seen in a previous post: www.flickr.com/photos/cameragirl108/10702196894/) which runs north-south through New Mexico, and the Jemez Lineament, which extends from southeastern Arizona northeast to western Oklahoma. The volcanic activity here is related to the tectonic movements of this intersection.
It exploded 1.2 million and 1.6 million years ago, piling up 150 cubic miles of rock and blasting ash as far away as Iowa … that’s roughly equivalent to 2,000 Mount St. Helen’s eruptions. All that material being erupted from a magma chamber leaves a pretty big void, and the vast bowl of the Valles Caldera formed when the caldera floor (or magma chamber roof) collapsed into that space. Ash deposits contributed tuft to the surrounding Jemez Mountains, and created many of the formations in Bandelier National Monument, where the Ancestral Pueblo people built their homes. Valles Caldera is the younger of two calderas known at this location, having collapsed over and buried the older Toledo Caldera, which in turn may have collapsed over yet older calderas.
The Valles Caldera is one of three active calderas in the United States (Yellowstone is another.) It encircles a field of volcanoes whose resurgent domes (magma rising from under the crust) split the caldera into five sections, or valles (which means valleys without trees in Spanish.) The largest of these, Valle Grande, is almost 6.2 miles (10 km.) long and 3.7 miles (6 km.) wide. A magma chamber seethes just 3.1 miles (5 km.) below the idyllic grassland surface of the Valle Grande. During several geologic periods, multiple lakes existed in Valles Caldera. The most recent lake drained the Valle Grande 55,000 years ago.

Three times in my life I have been near active volcanoes but did not visit through missed opportunity and mostly due to my immature and unorganized interest in geology. While I was lamenting my long ago missed opportunities and continued to hike in and around long dormant volcanic areas in my region, I researched active volcanism - the Salton Sea and its mudpots were my answer.
The mud volcanoes and mudpots or fumaroles erupting on the surface are pockets of hot water and gas (carbon dioxide) rising to the surface causing the mud to liquify and then be ejected to the surface creating the cone shape around the vent. This of course is not a true volcano that ejects molten rock (magma). The area smelled of sulphur and other gasses.
I didn't have enough time to really explore as this was a stopover on our drive home and look forward to going back to explore further.
Today was exceptionally beautiful. The weather was well-nigh perfect. And it was Saturday. Went to where I store the bike and first order of business was to re-grease the clutch bucking bar, a small cylinder which is used to engage the clutch, because there's a little squeaking sound when I push the bike and I don't like that. haha. Then re-tighten the head bolts, the motor mounts, the carb float bowl screws and the exhaust and intake port nuts. Takes all of 3 minutes. Topped off the tank with my hand-mixed gas/oil solution.
Pedaled a few feet, popped the clutch and she started right up. Sounding great. Then up the hill...up up up, climbing. Still there are a couple of places on the back side of Yang Ming Shan that require a few pumps on the pedals, usually if it bogs down to 14 mph, which is seldom.
On up through the park and then up the main drag to Xiao You Keng. This is a large fumarole on the northwest side of Seven Star Mountain (七星山). Smoulding sulphurous steam clouds swirl continuously. This is also the crest where one can descend to the northern coast.
I decided to take an alternative ride on another crest (goo.gl/maps/QBs1o) which leads down to Danshui...but only went a short before turning around and going back down so I could take some nice shots of Xiao You Keng in the superb late-afternoon light.
The bike continues to run exceptionally well. I usually push it WOT (wide open throttle) on all the steep grades. It doesn't care.
I've not put a single cent into this bike in months and months. There's no maintenance other than tightening the bolts once in a while, and optionally greasing the bucking bar. No filters to change. No oil to change. The drive chain which caused me so much grief in the beginning has remain perfectly adjusted after hundreds of miles.
I am very thankful to have had this wonderful day riding on my China Girl in perfect weather in the outstandingly beautiful mountains of Yang Ming Shan!

The name of Yellowstone National Park's "Mud Volcano" feature and the surrounding area is misleading; it consists of hot springs, mud pots and fumaroles, rather than a true mud volcano. Depending upon the precise definition of the term mud volcano, the Yellowstone formation could be considered a hydrothermal mud volcano cluster. The feature is much less active than in its first recorded description, although the area is quite dynamic. Yellowstone is an active geothermal area with a magma chamber near the surface, and active gases are chiefly steam, carbon dioxide, and hydrogen sulfide. However, there are some Mud Volcanoes and Mud Geysers elsewhere in Yellowstone. One, the "Vertically Gifted Cyclic Mud Pot" sometimes acts as a geyser, throwing mud up to 30 feet high.
With half of the earth's geothermal features, Yellowstone holds the planet's most diverse and intact collection of geysers, hot springs, mudpots, and fumaroles. Its more than 300 geysers make up two thirds of all those found on earth. Combine this with more than 10,000 thermal features comprised of brilliantly colored hot springs, bubbling mudpots, and steaming fumaroles, and you have a place like no other. Geyserland, fairyland, wonderland--through the years, all have been used to describe the natural wonder and magic of this unique park that contains more geothermal features than any other place on earth.
Yellowstone's hydrothermal features would not exist without the underlying magma body that releases tremendous heat. They also depend on sources of water, such as from the mountains surrounding the Yellowstone Plateau. There, snow and rain slowly percolate through layers of permeable rock riddled with cracks. Some of this cold water meets hot brine directly heated by the shallow magma body. The water's temperature rises well above the boiling point but the water remains in a liquid state due to the great pressure and weight of the overlying water. The result is superheated water with temperatures exceeding 400°F.
The superheated water is less dense than the colder, heavier water sinking around it. This creates convection currents that allow the lighter, more buoyant, superheated water to begin its journey back to the surface following the cracks and weak areas through rhyolitic lava flows. This upward path is the natural "plumbing" system of the park's hydrothermal features.
As hot water travels through this rock, it dissolves some silica in the rhyolite. This silica can precipitate in the cracks, perhaps increasing the system's ability to withstand the great pressure needed to produce a geyser.
At the surface, silica precipitates to form siliceous sinter, creating the scalloped edges of hot springs and the seemingly barren landscape of hydrothermal basins. When the silica rich water splashes out of a geyser, the siliceous sinter deposits are known as geyserite.
