Yellowstone National Park: Part 2B.  The living creatures of Mammoth Hot Springs

Continuing our tour through the Mammoth Hot Springs. It was a surprise for me to learn that the hot spring colors are produced by living creatures! Thermophiles are microorganisms that thrive in heat. Those living in the hottest water are colorless or yellow.

The people of the Shoshone and Bannock tribes came to Mammoth to collect minerals to make white paint.

Cooler waters contain orange, brown and green thermophiles. Sunlight also influences which colors you may see.

 

 

When hot springs rise up through limestone, they dissolve calcium carbonate. The resulting calcite is then deposited, creating travertine terraces.

These are the Palette Spring terraces coming down from the thermal pool above them.

.To my surprise, there were quite a few birds hopping about, including a chipping sparrow (Spizella passerina) and very colorful yellow-rumped warblers (Setophaga coronata).

 

Mountain bluebirds (Sialia currucoides) were a delight to see.

 

The trail through the Hot Springs complex winds around for more than 2 miles. As I was walking along one area at the bottom of a steep hill, some fellow tourists approaching me said there was a coyote going up the hill further on. I hurried on and caught sight of him as he neared the top.

You reach the Upper Terraces by climbing steep stairs.

There were more trees along the upper pathway with fumaroles (venting steam) nearby.

I did catch sight of some eagles soaring over the large flat springs expanse, but I was happy to go back down to the lower terraces. (Unfortunately, sliding my gloved hand down a wooden railing on the descent gave me a splinter in my palm that I did not manage to get out completely. I had a very sore hand for quite some time: unwanted souvenir!)

I lost track of exactly which places had which names — looking them up on the Internet is not always helpful because the Mammoth features have changed considerably over time. When a hot spring remains dormant for a long time, it will eventually be covered by soil and again create an environment for trees and flowers. To complicate matters, the names of sites have changed over time.

The name Cleopatra Spring has been given to at least three different sites over the years. The original Cleopatra Spring eventually came to be called Minerva Spring. This was, I believe, the current Cleopatra Terrace.

 

When trees are flooded by hot water, they absorb calcium carbonate. This hardens their veins so they cannot absorb “normal” water and nutrients and they harden into what look like petrified trees which may stand for decades.

The hot springs were an early commercialized attraction for those seeking relief from ailments in the mineral waters.

Today, to preserve these unique and fragile features, soaking in the hot springs is prohibited.

Yellowstone National Park: Part 2A. Mammoth Hot Springs and women in the park

On 19 May 2022, Joan and I had our first full day in Yellowstone National Park (YNP).  This two-part blog covers what we did in the morning: an excursion to the Mammoth Hot Springs, only 5 miles from the Gardiner/Roosevelt Arch entrance. Shortly after passing through the gate, we caught sight of a river running alongside the road. We had no idea that within 20 days, this river would rise and take out part of the road on which we traveled! The recovery effort has also been phenomenal and the National Park Service has done a great job opening up the park again.

About 10 minutes into the park, Joan called out that she had seen a bear! She pointed to my side of the road and, looking up, I saw the bear on a hillside beside some rocks — she was enormous (perhaps the biggest we saw). She was also accompanied by offspring so I began scrambling to get my camera. By the time we got to a pull-off, they had disappeared behind big boulders and did not reappear. She looked somewhat like the (blurry) bear below that we saw another day when we couldn’t stop (rangers were present and moved everyone along). This spotting was certainly an exciting beginning to our YNP adventure.

This sighting taught me that Joan would be an excellent wildlife spotter even when guiding the car along winding roads with sometimes steep drop-offs at the side! It was cold our first day and we dressed warmly – long pants, sturdy shoes, sweaters, warm jackets and caps.

I was glad that we didn’t have to gallivant around in the long dresses and headgear worn by the first women who visited the park. However, the early female visitors to YNP were no “delicate flowers” as I learned from a book of their writings (Sidesaddles and Geysers: Women’s Adventures in Old Yellowstone. 1874 to 1903. Edited by M. Mark Miller).

Carrie Strayhorn wrote, after her 1882 visit to YNP, that both men and women clambered all over the mineral deposits. She and her party traveled about 400 miles on horseback through the park, leaving her with memories of “the charms of nature which go with the wilderness and wonders in all their primal glory.” Strayhorn visited Mammoth Hot Springs and we made that our first stop. (Photo from “Fifteen Thousand Miles by Stage (1911) by Carrie Adell Strahorn)

At the entrance to the Mammoth site, we were met by brown-headed cowbirds (which we have in North Carolina) and black-billed magpies (Pica hudsonia).

The first thermal feature we neared is called the Hymen Terrace. Old records kept at the University of Wyoming Libraries contained an enthusiastic description of this site.

As our day had started off quite overcast, this thermal did not look very colorful or terribly fascinating, so we moved on to walk along the trail.

Off to the side was a structure of some 37 feet in height (11 m) known as the Liberty Cap.

It received this name in 1871 from people who thought it resembled the caps worn by French revolutionaries who fought for freedom and liberty. It looked a bit more interesting when the skies cleared and the sun appeared.

The Mammoth site’s thermals mainly include hot springs and travertine terraces. Joan generally walks much faster than me and I stop often to photograph, so we split up to see the sights.

As Joan took off down a boardwalk, I stopped to photograph my first view of a Clark’s nutcracker (Nucifraga columbiana). I hadn’t expected to see many birds around the thermals so it was a welcome surprise.

 

Hot springs are Yellowstone’s most common thermal features. They comprise pools, sometimes quite deep, of heated water that may be calm and clear or froth like boiling water.

Rain and snow bring water that seeps into the earth where it is heated. It is still not certain which volcanic heat source is responsible for this.

It might be the magma chamber underlying the Yellowstone Caldera or another smaller place nearby. According to researchers, only 10% of the water in the Mammoth area is above ground at any one time.

What looks like steam arises from the hot springs and this seemed to be especially the case when we were viewing them in colder temperatures. Here you can see how our view of the Palette Spring changed as the day started warming up.

Frigid days and thirsty birds

Before my next Yellowstone blog (later today; I’m on a roll after a long posting absence), I wanted to share a tip with those of you concerned about birds when you’re confronted with frigid temperatures.

Here in the Southeastern USA, our late autumn/winter season has so far been a temperature roller coaster. We have gone from afternoon temperatures in the 50s and 60s F° (about 10-15 C°) to morning lows of 10 to 25 F° (-12 to -3 C°).

My porch features some shallow plastic plant saucers that I keep filled with water and a solar fountain. The smaller birds especially like to get drinks there because it is more sheltered than the bird baths out in the yard. However, that water has been frozen and birds began chipping at it fruitlessly to get a drink.

As a hiker, I often use hand, toe and body warmers when I walk in the cold. So it occurred to me that I might use them to provide the birds with some liquid refreshment in the cold. Wikipedia explains what they are: “Air-activated hand warmers contain cellulose, iron, activated carbon, vermiculite (which holds water) and salt and produce heat from the exothermic oxidation of iron when exposed to air.” The small packets are shaken to activate them and then they give off warmth for about 8-10 hours.

I taped some of the hand and body warmers to the bottom of plastic containers and ceramic dishes and it has worked really well. Even in freezing weather, the warmers keep the water in the containers liquid all day for birds like the tufted titmice below.

 

As you can see from the accompanying photos, a variety of birds have been using them and it’s been rewarding for both them and me! As I write this in front of my porch window, a yellow-rumped warbler stopped by for a drink.

The larger birds like the crows have not come onto the porch but I hope they have strong enough beaks to break through ice in the ponds and puddles.

The coming week, our temperature roller coaster will return. We’re now expecting to have temperatures in the next two weeks reaching about 65 F° (18 C)!!

As you’ll see in the next blog, when my friend and I visited Yellowstone in the spring, we also encountered temperature roller coasters. Some days we started off bundled up for winter and ended with our jackets off in the afternoon. I am immensely grateful that I’ve been able to cope with these climatic circumstances and will maintain my wood pile in case we lose electricity later this winter and I need to use the fireplace.

 

Yellowstone National Park, Part 1. Wonders and delight

Yellowstone National Park (YNP), which is located mostly in Wyoming but also in Montana and Idaho, became the USA’s first national park on 1 March 1872. This year, the National Park Service was gearing up to celebrate Yellowstone’s 150th “birthday” and many visitors were expected.

Unfortunately, in June, storms led to catastrophic flooding of the park. Historic water levels caused mud and rock slides, leading to large-scale destruction of park infrastructure. Many road sections were destroyed and the town of Gardiner, at the North entrance, was devastated just as residents were welcoming the first summer visitors. Fortunately, significant progress has been made by the National Park Service throughout the summer and fall and entry into the park through the North and Northeast Entrance roads was restored in late 2022.

In late May, just before this episode of climatic devastation occurred, I had the very good fortune to travel through Yellowstone with my good friend, Joan. I’d visited YNP before, but this was my most enjoyable journey so far. I’d now like to share with you some of the sights we were privileged to see in a series of blogs (sometimes interspersed with some North Carolina wildlife sightings).

Yellowstone, which has a name based on an Indian word, is an area full of wonders and delight. You find yourself traveling through a large volcanic caldera — an immense depression left in the earth after a volcano erupts and then collapses in on itself. You are also in an area with the largest high-elevation lake in North America, a 670-mile waterway which is the longest free-flowing river in the Continental USA, and a spot where you are half-way between the equator and the North Pole. This area has had human occupants for at least 11,000 years according to archeological findings at nearly 2000 documented sites. Tragically, the settlers of European backgrounds and US authorities did all they could to drive the American Indian occupants away. Starting in 1886, when the US Army managed the Park, the US Cavalry patrolled it for 32 years to prevent the 27 modern-day associated tribes from hunting and gathering there. Finally, today, the Indian occupants are being rightfully acknowledged and highlighted in YNP educational and informational materials.In 1926, George LaVatta, Organizational Field Agent, led a group of Indians in costume into YNP.

To start off the blog series, I’ll introduce you to the place where Joan and I stayed: Gardiner, Montana, a town of only some 800-900 residents. The town comprises mostly hotels, shops and eateries. During the COVID pandemic, a couple restaurants burned down and were not replaced. We were there during the week before high season began and only a few of the remaining restaurants were open.

Neither Joan nor I were impressed with the cuisine on offer, so we began getting take-out at the local Gardiner market, a store with a nice broad selection of foodstuffs, some souvenirs and friendly staff who still served customers during a power outage.

While tourist season hadn’t begun, locals did show artwork and signs welcoming visitors.

                           

It was fairly easy to find places as there is only one main road with a limited number of side streets. A couple churches are prominent on the main drag, and one usually has some elk and/or or mule deer occupying space on their grounds.

Look well: there is an elk sheltering under the roof overhang.

  

There were warning signs here and there, reminding us of precautions for COVID and maintaining distance from wildlife, but this was disregarded in town.

   

Having walked through the backstreets to photograph birds, I can attest to the fact that it is not uncommon to turn around and find a deer or elk a couple feet behind you or moving just in front of you.

The Gardiner Catholic priest does attempt to prevent humans from taking up parking space.

A few of the houses along the main road had made some attempts at gardening, protecting plants from browsing mammals and being imaginative with rocks.

  

 

A little lending library was a nice touch, too.

As is the case in the Park proper, a great deal of care is given to avoiding trash on the ground. In 1970, open-pit garbage dumps were abolished in YNP, along with the nightly “bear shows” where visitors sitting on wooden bleachers watched bears eat garbage!

The local people do care about what is happening in the area and made this clear with signs.

     

In the park itself, visitors are warned not to move things around, like this geodetic marker.

$250 fine or imprisonment for disturbing this mark.

Our motel manager was friendly and told us about how the pandemic had made business difficult. In the past, many younger and retired people came to Gardiner and YNP to work in the motels, gift shops and other venues during the high season. I met some nice retired folks and students who had come for this reason (note the traveling home that someone had brought along).  The manager mentioned that there were now far fewer workers, however, and she and her son had been helping clean the motel rooms due to staff shortages.

When entry into YNP through the famous Roosevelt Arch was closed because of the June flooding, Gardiner took another post-pandemic blow. Hopefully, the town residents have been able to recover and can look forward to seeing more business in the seasons to come.

Next up: Visiting our first group of thermal features.

Adorable anoles — lizards with moods!

Hello, readers — it’s been a while! Time seems to be passing ever faster for me with each new year of life. I was surprised to realize that it’s been a couple months since I posted a blog. So here is a column that I just submitted to a local newspaper with a few more photos than the paper could accommodate.

One of my favorite local reptiles is the Carolina anole (Anolis carolinensis). These cute lizards can be seen year-round since they don’t hibernate. In my experience, however, they seem to be more active — or at least viewable — in late summer and early autumn.

Also known as green anoles, they are the only anoles native to the southeastern United States. Green is nevertheless not their only color. You may encounter dark brown, light brown and green/brown anoles and they might even change their coloring as you watch them.

Unlike chameleons, who change color to blend in with their surroundings so that they can hide more easily from predators, anoles mainly change their skin hues in response to stress or their mood, when they are active or when they want to defend a territory. Darker colors may indicate that they are feeling cold or stressed out.

Sometimes when I’ve watched individuals at length, it’s seemed to me as if they were expressing a variety of moods, even if they didn’t change color.

  

 

Full-grown males are larger than females, but you can also guess their sex based on anatomical features. When males hope to attract a female for mating, they display a brightly colored reddish flap underneath their jaws called a dewlap. When a female sees it, this may induce her to ovulate. Males also show their dewlaps when defending territory against other males.

   

Female anoles can often be distinguished by a row of white markings along their spine, which most males lack.

Like other lizards, anoles regularly shed their skin. Observation last year taught me that they may also eat that skin since this provides them with extra nutrients that may be lacking in their direct environment.

 

Their regular diet is varied, including flies, beetles, spiders, cockroaches, worms, ants, termites, moths and butterflies. Seeds and grains can form part of their meals as well.

    

Carolina anoles are known as arboreal lizards because they spend a lot of time in trees and shrubs. From a higher perch, they can survey their surroundings. Climbing up shrubs and trees can also help them escape from predators who cannot follow them because they lack the sticky foot pads that enable anoles to ascend vertically. Other predators, such as tree snakes and larger lizards, can catch them if they are quick.

 

Sometimes, a predator may catch a green anole by the tail and the anole escapes by dropping its tail—a defensive behavior known as caudal autotomy. A new tail will grow but will be weaker as it contains cartilage instead of bone and often will not be as long.

 

Recently, I learned that birds also hunt anoles when I photographed a blue jay who had caught one. Other birds in our area who go after them include kestrels and bluebirds.

 

The Carolina anoles usually live from about 2 to 8 years. A few who live around my front porch sometimes approach me closely and it’s noticeable that they are watching me, too.

  

Another one decided that an unused bluebird nest box was a good place to hide from predators, obviously not during birds’ nesting season!

It’s been so nice to see the anoles out and about the past weeks. Tonight, we’re having our first freeze of the 2022 autumn/winter season so the anoles may start seeking warm places to hang out. Hopefully, they will have found good places to over-winter.

Readers in the southeast USA who would like information on how to create habitats that can harbor anoles and other native reptiles and amphibians can check out this information site: Reptiles and Amphibians in Your Backyard.

  

My next blog will be the first of a series about Yellowstone National Park. I’d originally planned to post the series this past summer but then couldn’t find some photos I’d taken. The missing card “turned up,” so a photographic tour of the park before it flooded this past June will soon commence.

Have a great day!
