Such amazing formations can be seen at Mammoth Hot Springs, Yellowstone National Park. I thought it would be so easy to remember, or at least place on a map, each of the different formations we saw and photographed. However, I'm finding it more difficult than I thought, especially as many of the formations change over the years and so other photos on the Internet often look different. I think this was Minerva Terrace, but would really appreciate it if anyone out there can either confirm or correct my ID - thanks! I visited Mammoth Hot Springs and the rest of Yellowstone National Park 30+ years ago, when my kids were very young. Loved Mammoth Hot Springs, so was thrilled to get the chance to see this fascinating area again. This time, it was while I was on a wonderful week's holiday with special friends from England, in September 2012. We visited Mammoth Hot Springs on 12 September. "Mammoth Hot Springs is a large complex of hot springs on a hill of travertine in Yellowstone National Park ... It was created over thousands of years as hot water from the spring cooled and deposited calcium carbonate (over two tons flow into Mammoth each day in a solution). Although these springs lie outside the caldera boundary, their energy has been attributed to the same magmatic system that fuels other Yellowstone geothermal areas... A caldera is a cauldron-like volcanic feature usually formed by the collapse of land following a volcanic eruption. They are sometimes confused with volcanic craters." en.wikipedia.org/wiki/Mammoth_Hot_Springs For a diagram of the Hot Springs layout: en.wikipedia.org/wiki/File:MammothHotSprings.JPG Map of Yellowstone National Park: hfc.nps.gov/carto/PDF/YELLmap2.pdf

This was an absolutely amazing week away with my friends, Linda and Tony, from England. I had known Linda since she was a baby and I was four or five years old, and our parents were best friends. Believe it or not, this was only my second holiday in about 30 years! Some of you may just remember that when my Brother in England died, several of my long-time friends who lived in the same city all stepped forward and helped me deal with everything long distance, from my Brother's funeral to finding everything possible in the house a good home (sold or donated). All my parents' belongings were there, too, so it was a mammoth task to go through everything and put aside every single personal item or document, which were then shipped to me here. When Linda and Tony were planning their trip to Canada, they persuaded me to join them for this wonderful week in Yellowstone National Park. I didn't know we were also going to Grand Teton National Park and then coming home via Glacier/Waterton National Parks, too! A wonderful treat! It's not easy to remember what all the different hot springs and geysers are in Yellowstone National Park, so hopefully I am identifying them correctly. I believe this hot spring is Abyss Pool, which is near the Black Pool, at the West Thumb Geyser Basin. Amazing how similar some of them look - especially once you are back home after your trip and a year and a half has gone by! In the distance is Yellowstone Lake. "Temperature 172°F. Dimensions 30x57 feet. Depth 53 feet. Abyss Pool is a colorful and interesting pool in the West Thumb Geyser Basin. Abyss is the deepest pool known in Yellowstone and received its name for its abyss-like depth. The dark green-colored water gives the illusion of a bottomless pool. Vandalism may have changed this pool's temperature. Coins and other debris thrown in have caused the vent to plug. The reduced spring flow also reduced the pool temperature, allowing abundant algae growth along the edge and run-off channels. The extensive microbial mats now support ephydrid flies, spiders and killdeers. An unusual eruption in 1987 caused the pool to surge and temporarily destroyed the microbial mats." www.yellowstonenationalpark.com/westthumb.htm

Another photo from my archives. On day three of my wonderful week's trip down to Yellowstone National Park and Grand Teton National Park with special friends from England, Linda and Tony (explanation is in my "US holiday, September 2012" set), we visited Midway Geyser Basin, along the Firehole River. Photographed on 13 September, Yellowstone. Grand Prismatic Spring, Excelsior Geyser Crater and Turquoise Pool are also at this Basin. "Opal Pool is a hot spring in the Midway Geyser Basin of Yellowstone National Park, Wyoming. Opal Pool usually has a temperature of approximately 132 °F (56 °C). Though usually active as a hot spring, Opal Pool is considered a fountain-type geyser. The first recorded eruption of Opal Pool was in 1947, recurring in 1949, 1952 and 1953, then ceasing. Eruptions resumed in 1979, happening at least once in most following years. Eruption heights are typically under 30 feet (9.1 m) in height, but some eruptions have been seen with heights of 70 feet (21 m) to 80 feet (24 m). Eruptions occur suddenly following visible convection in the pool, but are unpredictable. The eruption consists of one, huge, burst that throws water 20-80 feet high, making Opal Pool the largest active geyser at Midway Geyser Basin. Much smaller splashes seconds apart stretch the total duration to about 1 minute. Sometime in 2005 Opal completely drained, but it refilled as a beautiful green pool in 2008."

I still have so many photos to go through properly, taken on my week's trip with friends from England, down to Yellowstone and Grand Teton National Parks in September 2012. This photo shows one of the hot springs close to the boardwalk at West Thumb Geyser Basin in Yellowstone National Park.

Congratulations to Americans, everywhere! That was a pretty tense evening yesterday, waiting to see if President Obama would be elected to serve another four years, or if the US would have a brand new President. Actually, I knew the result before anyone else, lol! How? Because I fell asleep in front of the TV part way through the evening and had a great dream in which I watched Michelle Obama reacting with joy at the announcement that her husband had won, ha, ha. I woke with a start, maybe 30 seconds before the very final predictions were announced on TV, saying that Obama was in. Another view of the beautiful patterns and formations around the Grand Prismatic Spring, Yellowstone National Park, Wyoming, US. You can see the steam rising from the huge spring at the top of the image. In some places, the colours were more vibrant and orange, as in my photo below. I think the photo in the comment box is perhaps my favourite photo from around the Grand Prismatic Spring. "The Grand Prismatic Spring in Yellowstone National Park is the largest hot spring in the United States, and the third largest in the world, after Frying Pan Lake in New Zealand and Boiling Lake in Dominica. It is located in the Midway Geyser Basin. Grand Prismatic Spring was noted by geologists working in the Hayden Geological Survey of 1871, and named by them for its striking coloration. Its colors include blue, green, yellow, orange, red and brown, and recall the rainbow disperson of white light by an optical prism. The vivid colors in the spring are the result of pigmented bacteria in the microbial mats that grow around the edges of the mineral-rich water. The bacteria produce colors ranging from green to red; the amount of color in the microbial mats depends on the ratio of chlorophyll to carotenoids and on the temperature of the water which favors one bacterium over another. In the summer, the mats tend to be orange and red, whereas in the winter the mats are usually dark green. The center of the pool is sterile due to extreme heat.... The spring is approximately 250 by 300 feet (80 by 90 m) in size and is 160 feet (50 m) deep. The spring discharges an estimated 560 US gallons (2,100 L) of 160 °F (70 °C) water per minute."

Taken at the West Thumb Geyser Basin in Yellowstone National Park, Wyoming, US, on 15 September 2012. The deposits around the edge of this hot spring, Black Pool, made such a colourful contrast to the almost turquoise colour of the water. My photo shows just one small portion of the the edge, taken from the boardwalk. "The pool was cool enough up until 1991 for dark orange-brown cyanobacteria to grow throughout the pool. When combined with the blue of the water, the pool appeared to be an exceptionally dark green to almost black, hence the name." An exchange of function took place in 1991, shifting thermal energy to Black Pool and nearby Abyss Pool, causing them to heat up. Black Pool's temperature became hot enough to kill all the cyanobacteria in the pool, turning the pool a rich teal blue color. The pool also had frequent boiling eruptions on August 15, 1991, doming the water to 3 feet and causing heavy runoff. Black Pool remains extremely hot, and is now one of Yellowstone's most beautiful and intensely blue pools. The name of the pool remains "Black Pool." From Wikipedia. The dark orange-brown cyanobacteria seems to be back along this one edge of the spring. "Temperature of Black Pool is 132°F. Dimensions 40x75 feet. Depth 30 feet. Black Pool is one of the largest springs in the West Thumb Geyser Basin. The dark-colored water is the combination of the natural, transparent blue of the water and the orange algae lining of the pool. The low temperature of the pool is responsible for the abundant growth of the orange-colored microbial mats. Algae and cyanobacteria in combination with sinter deposits have created coral-like formations on the sides of the pool but these are visible for only a few feet. The pH of Black Pool is a slightly alkaline 7.8." www.yellowstonenationalpark.com/westthumb.htm

Part of one of the hot spring formations at Mammoth Hot Springs, Yellowstone National Park, Wyoming, US. Taken on 12 September 2012, the second day of our week's trip from Calgary down to Grand Teton National Park. Not sure if this is part of Palette Spring, but this wonderful mix of natural colours would fit perfectly into the name. Bacteria and algae create the streaks of color, forming tapestries of living colour.

Not sure if this is Emerald Pool or Rainbow Pool! I've seen a lot of photos that name it as Rainbow Pool, but just found others that name it Emerald, which makes more sense to me. Continued research is needed! Think that maybe Emerald is the correct one. "Temperature 154.6°F Dimensions 27x38 feet. Depth 25 feet. Named for its emerald green color, it is one of the main attractions at Black Sand Basin. The color is the result of lower temperatures which have allowed yellow bacteria and algae to grow on the lining of the pool. The clear water of the pool reflects the blues but absorbs the other hues of the color spectrum. The combination of blue and yellow then produces green. Objects thrown into the pool and natural debris have caused a further decrease in temperature, resulting in a change of bacteria and algae growth and thus a change of color. The edge of the pool is now orange and brown. If the temperature continues to decrease, the pool may lose its emerald color." www.yellowstonenationalpark.com/blacksand.htm

I still have all sorts of photos from my week's holiday with my friends from England that I haven't posted yet. This hot spring is now surrounded by the waters of Yellowstone Lake. Taken on 15 September 2012, the fifth day of our trip. "Fishing Cone is a geyser in the West Thumb Geyser Basin of Yellowstone National Park in the United States. In the earlier part of the 20th century, this cone had eruptions as high as 40 feet (12 m). As the water level in Yellowstone Lake has increased, the cone is now inundated during the spring and the temperatures in the cone have cooled enough that it no longer erupts and is now considered a hot spring. The name Fishing Cone can be traced back to tales told by mountain men of a lake where you could catch a fish then immediately dunk it into hot spring and cook it on the hook. A member of the 1870 Washburn-Langford-Doane Expedition popularized this feat." en.wikipedia.org/wiki/Fishing_Cone

Taken on the third day (13 September 2012) of a week's trip with great friends from England, down to Yellowstone National Park and Grand Teton National Park. This beautiful pool is located at the Black Sand Basin. I still have so many photos to go through from this holiday, and am trying to slip the occasional one on to my photostream. "Temperature 154.6°F Dimensions 27x38 feet. Depth 25 feet. Named for its emerald green color, it is one of the main attractions at Black Sand Basin.

I thought this was such a beautiful sight, looking down into the thermal water at Mammoth Hot Springs, Yellowstone National Park, Wyoming, US. It was taken somewhere near Canary Spring, on 12 September 2012, the second day of a week's holiday with friends from England.

The contrast of deep, almost turquoise water with the white and vibrant orange deposits around the edge of hot springs in Yellowstone National Park was just breathtaking. Made for some interesting patterns and textures. Taken on 15 September, the 5th day of an amazing week's trip with friends, when we stopped at the West Thumb Geyser Basin. My photo shows part of the edge of Black Pool. "Temperature of Black Pool is 132°F. Dimensions 40x75 feet. Depth 30 feet. Black Pool is one of the largest springs in the West Thumb Geyser Basin.

I really liked this particular area of hot springs in Yellowstone National Park, West Thumb Geyser Basin, as it was interesting to see how some of them were actually just off-shore, in Yellowstone Lake itself. My image shows one of the springs flowing into the lake, over the colourful deposits and growths. Taken between Big Cone and Black Pool. From this spot, we were happy to see two (or was it three?) beautiful Bald Eagles in the dead trees at the edge of the Basin. Somehow, I just wasn't expecting to see these majestic raptors in a place like this. I hope you're not getting TOO fed up of hot spring photos, especially as I still have a lot more to go through!
