Yellowstone: Canyon Country
The "grand canyon of Yellowstone" is what keeps people coming to Canyon Country--a deep, creamy yellow canyon carved by the Yellowstone River, direct from where it starts miles away at a placid Lake Yellowstone, before it becomes a raging force down two falls (Upper and Lower), and wends north to ultimately meet the Missouri. Other highlights are Hayden Valley, a lovely green swath full of bison this time of year, and a particularly pungent collection of hot springs.
All artists love Lower Falls, here seen from a north rim pullout. There are also lots of viewing places down near the head (brink) of the falls along a winding trail down. The south side of the canyon offers its own views, some with boardwalk steps that cling to the side of the canyon.
Yellowstone Canyon, as seen from the brink of Lower Falls. The sun that day was glorious.
A bison jam in Hayden Valley: traffic is stopped for two miles in both directions.
Bison were meandering across the road toward grazing lands along the river. They do this a lot--back and forth throughout the day.
Although it ultimately took us 40 minutes to get past the moving blockade, it was hard to get irritated at the delay...I'd rather stop for bison than for 5 0'clock traffic any day.
Two babies. The caramel-brown one is younger, a later arrival that may have trouble in the winter if it doesn't get really strong really soon.
No worries for this crowd even with cars piling up on the road. The dust cloud is from a bison rolling in a wallow.
This pair forced us to a halt by walking directly in front of our truck--and stopping! Note the size difference of the male (back) and the female (front). She looked straight at us as they paused for a bit, then they slowly moved on as if hitched together. Those two people up ahead are park employees. They show up at heavy traffic stoppages to make sure animals like bison and bears aren't harassed by photo-hungry tourists and that no one is injured; they don't do much to hurry or guide the animals along. Critters run the show in Yellowstone.
The pair paused and looked at us again near the other side of the road. Still no moving for our truck until they were completely off the pavement...with the male's butt within scritching distance through my window (no, I didn't).
The bison seemed to enjoy walk into traffic and stopping. This one held up the line for several minutes. Another stood in front of a motorhome for more than ten minutes before it decided to move on. Generally neither lane of traffic could move, because a bison is just as likely to turn around and go back as to continue the way it is facing. A little later another one stopped in the road because its right forefoot was sore...it held it up gingerly and finally limped away and paused again just a short distance from the road for another rest.
Canyon Country has its own set of hot springs and fumaroles with interesting names like Mud Volcano and Sour Spring. This is Dragon's Mouth, a wonderfully noisy and active spring that spits water through the opening in belching, steaming waves. The entire area is highly sulfurous, making a great stench as well.
Bison own the land...even along a walk that thousands of people use to reach other springs in the area. This one just hung around his wallow, chewing cud and flicking dust onto his back with his tail.
I could have been at a zoo taking his photo, except that there's no fence between us. Thank goodness for zooms.
Churning Caldron [sic], one of the many appropriately named hot springs in this area. This spring was really fun to watch--it boiled up incessantly like some soup gone mad.
Sulfur Spring, one of the world's most acidic bodies of water. It's pH is like battery acid. The gorgeous hills in the backdrop are at the edge of Yellowstone's famous caldera--volcanic crater--that extends for miles. That hill there is actually still rising and falling like an inflating and deflating balloon because of the volcanic action that continues beneath Yellowstone.
Another view of the Yellowstone River. Beyond the falls, it's generally shallow, wide, and quiet, with very few rapids.

Yellowstone: Mammoth Country
To me, the name Mammoth Country conjures images of woolly elephants roaming expansive plains, or at least the bones of the same found in layer after layer of sediment. Here in Yellowstone it just means BIG, in reference to the heaping mounds of calcium and limestone deposits built by boiling, mineral-laden springs that have seeped and flowed and deposited their microscopic debris over the millennia. It's like an inside-out cavern creation--hot water instead of cold, flowing bottom up instead of dripping top down, exposed to the air instead of hidden underground.
The area is appropriately called "terraces," and they change all the time...the water temps, winds, and general surface structure make the water flow in different directions even day to day. Sometimes the water flows in the same swath long enough for its minerals to form ridges that become ledges and walls, creating shallow or deep pools. You can always tell an active or "live" part of a terrace spring: colors like orange, brown, or yellows (created by heat-loving micro-critters) and slick, bright white (too hot to sustain life, pure calcium deposits) show areas that are thriving with water flow. Areas of gray, boulder-like color, and dry white spots no longer have water over them, leaving the mineral deposits behind in "dead" hills that might come alive again at any time as the waters shift.
This year this area of activity is quiet--no burping mud pits, hissing fumaroles, or exploding geysers. The waters bubble a little (activity has been bigger in previous years), you can sometimes hear the water dribble off a ledge, but it's mostly flow of a quarter inch of water down a wall. The usual smell of sulfur and other minerals pervades.
The terraces seen from a distance--not very inspiring until you get up close.
At the upper terraces.
"I told you the earth was flat!" Water streams over an unseen terraced edge.
Another angle of the top terrace pool, with lovely Mt. Everts in the background. That mountain was our view from the campground, less than a mile north of here.
The other side of the terraced pool.
A little farther down.
Snow white and boiling hot.
At the lower terraces. Orange means microbes, white means none, but hot water was still flowing.

A fantastic expanse of dry, "dead" calcium deposits was right next to wet, living flows.
A close-up of Palette Springs in this area--the living and the dead.
A cascade of water at the top of the lower terrace, also visible two shots above.
In the Norris region of Mammoth Country, you can enjoy nearly two miles of boardwalk over geyser territory.
Loved the colors of this mini marsh among the gray grounds surrounding it.

Two crystal-clear springs shimmer in the sun. They're only about two feet wide.
A distance shot of Mt. Bunsen, a hill we later hiked.
The early part of the trail.
Urg...it got steeper pretty quick.
Two miles later, we reach the top for spectacular views of the valley. We're looking toward the same road where I snapped the shot of Bunsen from a distance. It's the main thoroughfare through Mammoth Country.
More fire damage and recovery.
At the top of Bunsen is an communications center--microwave, cell, etc. Note the federally-funded antenna made of a Home Depot bucket and foil tape.

Yellowstone: Geyser Country
We came in from Montana, via the West Yellowstone entrance. This park is so big that it's got five ways in, and only a fraction of its 2.1 million acres is actually roaded and accessible for viewing by John Q. Public without backcountry camping among bears and mosquitoes.
We spent two weeks here, one week at an electric-only site at Baker's Hole in West Yellowstone outside the park, and another week at Mammoth campground, inside the park at the northern border. None of the in-park campgrounds have hookups, but the park was mobbed with tourists...more crowded than Ken has ever seen it. The campgrounds were all full by midday, and the few that would take reservations were booked weeks in advance. Non-reservation campgrounds are catch as catch can--you show up and hope something's open that will also fit your rig, then you can stay for up to 14 days without worry.
The day we moved to Mammoth we arrived too late for a site--it was full by 1:00 when Ken was used to seeing it fill by 3:00. We left the park and ended up at a forest service canyon campground nearly 20 miles away that night, barely getting a site there, either, for its being full and mostly suited for tents, not 28-foot rigs. The next morning we got a great spot at Mammoth that enabled us to fill fresh water from a nearby spigot and dump gray tanks by the bucketful at a nearby toilet. It was almost as good as full hookups, just less convenient.
For ease of management and touring, Yellowstone is divided into five "countries"--regions that have their own unique geological and wildlife features. Miles of loop roads link the countries, and rivers run through all of them. We visited all five countries, with the least time spent in the Lake area because we didn't go to the extreme southeast corner of the park (not much to see according to Ken, and comprising two roads that lead out of the park instead of through the area). I've given each of the other four countries its own photo essay here in the blog: Geyser, Mammoth, Canyon, and Roosevelt. You may want to read them in that order.
Geyser Country is quintessential Yellowstone--home of Old Faithful; holes and pools spewing vapor, water, and mud; and steaming springs lined with jewel-like colors. Contrary to what I expected, a lot of the region is actually rolling hills, meadow, and burned-out but recovering forest (from a devastating fire in 1988), dotted with bald spots of gray and white where the underlying volcano still actively boils water and generates associated geologic features. The area is particularly spectacular in the cool of the morning, when steam vents are most visible.
Touring Geyser Country is an exercise in driving from one viewpoint to another, finding a parking spot, walking boardwalks that extend far out over some of the geyser fields, and jostling for photos at the many points of interest. Busloads of Asians, rented motorhomes of Germans and French, motorcycle groups of big mamas and leather-chapped men, and cars and vans stuffed with families and touting plates from all across the US...it's summer in Yellowstone.
Most of the days that we toured and hiked were clear, warm, and sunny, making for some stunning color displays at several of the pools, flows, and springs. Most colors are created by heat-loving microbes living at varying temperatures, although a few are formed by minerals like sulfur (pale yellow) and calcium (white), and some by acids breaking down the soils (gray and browns).
