Yellowstone National Park

Yellowstone, the world’s first National Park! It was established as a National Park in 1872. It is on a volcanic hot spot, and is half scenic wildlife paradise, and half steaming hellscape. We were definitely excited for this visit.

The drive from Colorado through Wyoming was pretty uneventful. There are vast areas of this country with barely anyone in them! We drove through the Wind River Canyon just before dark, and it was very scenic. We ended up with a large bug collection on the truck, so the next day in Cody, WY we stocked up on groceries, and washed the truck and trailer. It has been awhile since we were so shiny!

We camped at Fishing Bridge RV park in Yellowstone, which is the only full-hookup campground in the park. We made reservations about two months ago, and they were the only reservations we had for this part of the trip. Yellowstone is so big that it’s important to camp within the park. Fishing Bridge RV Park was a bit of a tight squeeze, with no picnic tables or fire pits. They discourage eating outside because of bears. Brian was sad to learn fishing is no longer allowed from Fishing Bridge.  “Worst name ever” according to Brian.

Yellowstone National Park is on an active supervolcano, with the caldera from the most recent eruption (640,000 years ago) encompassing about a third of the park. Because there is magma is closer to the earth’s surface here, there are thousands of geothermic features in the park, including geysers, hot springs, mudpots, and fumaroles (the fancy name we learned for steam vents).

Hot springs are created when there are cracks in the earth letting heated water up to the surface. When the cracks in the earth include constrictions, these can become geysers. Fumaroles exist when there isn’t as much water as in a hot spring. Mud pots are created when the water is acidic.

Sixty percent of the world’s geysers are in Yellowstone. The geothermic features were amazing to see, but kind of scary too. There are boardwalks in different areas of the park that take visitors past many of these features, but one step off the boardwalk could boil a person alive!

The features are dynamic, a ranger told us that they have to move a boardwalk every five years or so because the features change. We saw evidence of this, there were a few places where the parking lots had steaming holes in them! It’s amazing that it is even safe to view these places.

There are several areas to view geothermic features, and each is different. We visited all of the main areas including Mammoth Hot Springs, Mud Volcano, West Thumb Geyser Basin, Upper Geyser Basin (where Old Faithful is), Fountain Paint Pot, Grand Prismatic Spring in the Midway Geyser Basin, and Norris Geyser Basin.

The first full day we were in the park we visited Old Faithful first thing in the morning. We got there just in time to see it erupt, and it went off about 8:30 am. What we didn’t expect was that it was so cold in the morning, and the eruption was basically a steam cloud! We decided to see it again, midday when it was warmer and we could see some water, too. The days tended to be chilly in the morning and hot in the afternoon, with lows in the 30s-40s and highs in the 70s-80s. The sunny days really feel hot at altitude, and locals commented to us that is was about 10 degrees hotter than normal.

The Upper Geyser Basin has a lot to see besides Old Faithful, so we walked around the boardwalk and saw other geysers, hot springs, and fumaroles. The colors in the water are caused by thermophiles, which are heat-loving bacteria. The different colors signify water temperatures, all of which are very hot. We consistently resisted the temptation to test the water temperature with our fingers!

Afterward, we decided to stop at Grand Prismatic Spring, which is the largest hot spring in the park. We pulled off at a parking lot near it, based on the not-very-detailed park map. We thought we were at a viewpoint or boardwalk, so we only brought out a water bottle and camera.

There was a trail, and many people headed out on it, but we found no information at the trailhead. So, we started out and headed in the direction of the spring. After about a third of a mile, there was a sign saying “trail ->”, but it was heading in the opposite direction of the spring so we stayed on the wider path we were on and didn’t take it.

After a couple miles it became apparent that we weren’t able to access the boardwalk around Grand Prismatic Spring. We could see the spring, but the boardwalk was on the other side.

We were already out there, so when we saw a handwritten sign saying “Fairy Falls 1.6 miles,” we decided to at least see a waterfall! It was a pretty boring hike, but the waterfall was nice.

After the waterfall we still didn’t really know where we were, so we continued on a bit, and found another hiker to ask what was down the trail. He told us there was a geyser a little ways ahead, so we kept hiking. Imperial Geyser was really beautiful, and somewhat redeemed the hike that we didn’t really mean to take. The geyser was within a blue-green pool, and we only encountered four other people while we enjoyed it. It was hard to leave it!

We often discuss (judge) all the seemingly unprepared hikers we see who barely bring any water on long hikes, but this time we were the idiots with one water bottle (between the two of us) on what accidentally turned into about an 8 mile hike.

The mistake we made was pulling in one parking lot too early to access the boardwalk to the spring. We also learned that the trail in the “wrong direction” was to a beautiful overlook of the Grand Prismatic Spring. Several days later, during Labor Day weekend, we returned and, what do you know, they had added information on the overlook trail at the trailhead! We completed the half mile hike to the overlook this time, and were rewarded with this view. It’s hard to believe this exists!

We also found the correct parking lot for the boardwalk. The Grand Prismatic Spring is impressive from ground level, too, but seeing it from above was really cool.

Mammoth Hot Springs are in the northwest corner of the park, and it took us about two hours to get there from Fishing Bridge campground in the southeast side. We happened to get there right before a ranger program at the Upper Terraces, so we joined and learned a lot about how the terraced hot springs are formed. This area has limestone, and when the hot water goes through it, it deposits calcium carbonate at the surface. This rock (called Travertine), can grow 6 feet a year!

The West Thumb Geyser Basin is right on the edge of Yellowstone Lake. There is a hot spring called Fishing Cone where they used to cook fish that had just been caught called “cooking on the hook”. That was a great idea until they discovered the hot spring contains arsenic.

The Mud Volcano area smelled especially like sulphur, which reminded us of rotten eggs and spent bottle rockets. It has mud pots, full of acidic water. The pH level was one up from battery acid. It was so hot and stinky walking through the steam coming off the features! Bison and elk like these areas, and seem to know where not to step. One of our favorite features here is called Dragon’s Mouth, and it hissed and gurgled as steam poured out of it, and occasionally a wave of water came out of the cave.

Fountain Paint Pot boardwalk went passed a mud pot that looks just like paint, and it was fun to see mud bubbles form and pop!

As we turned around a bend we saw Fountain Geyser just starting to erupt. It erupts every 4 hours or so, and keeps erupting for about 25 minutes. There are two types of geyser, cone geysers that typically shoot water straight up into the air (like Old Faithful) and fountain geysers, that slosh around and look more random. Fountain Geyser was beautiful and hypnotizing to watch. It reminded me of the Bellagio fountain. And just when we though it was dying down, it would shoot up again. There were two other geysers nearby (Jet Geyser and Clepsydra Geyser), and at times all three were erupting at once.

Later in the week we returned to the Old Faithful area, and remembered to check the visitor center for predicted times of the other large geysers in the area. We sat at Grand Geyser for an hour because the eruption could occur within an hour before or after the predicted time. Grand Geyser is the tallest predictable geyser and can be up to 200 feet. It erupts about twice a day. It was fun to see, but I don’t know if it was worth waiting so long in the hot sun. It’s a fountain geyser, and it was taller than Fountain Geyser, but not more beautiful.

While we were there, we saw a couple more eruptions of Old Faithful. It is easy to see why it is so popular. It erupts every 68 or 98 minutes (depending on the length of the previous eruption), plus or minus 10 minutes. The eruptions are very frequent and very predictable compared to other geysers that have estimated eruption windows that are plus or minus an hour or two. Midday on the Saturday of Labor Day Weekend was a busy time at Old Faithful!

Norris Geyser Basin is the hottest area of the park. Since different bacteria can live at different temperatures, this means that there are more colors in this area. Also, the entire area steams, especially in the morning when it is chillier!

Brian’s two most vivid memories from his trip to Yellowstone when he was 10 are being separated from his siblings at Old Faithful, and getting stuck in bison-related traffic jams. The very first night we drove through Hayden Valley and found ourselves stuck in a line of cars while bison blocked the road. Nearly every day we spent at least a few minutes stuck behind a bison. On our last day in Yellowstone we were stuck in traffic for an hour while a herd of bison had a parade on the road.

Hayden Valley is a beautiful area where there are always bison, but it is also where we witnessed some of the worst driving behavior in the park. Drivers were pretty terrible everywhere though. Every time there was wildlife near a road, people lost their minds. At one point a car stopped right on the road next to a bison, and the passenger was getting out of the car, when a ranger nearby announced over a loudspeaker “Do not get out of your car. Do not stop on the road.” These don’t seem like things that should have to be announced, but we saw people doing this all the time! There are so many cars on the road that the bad behavior is hard to ignore. It’s also crazy to see how close some people try to get to wildlife. It’s not like they don’t warn people! We kept our distance, and always carried our bear spray.

Everything is so far from everything else that we spent at least two hours driving each day, usually more. The park is set up as a figure 8, and the Grand Loop Road is 142 miles! It’s hard to complain about the driving distances though, since every road is scenic. We also spotted wildlife from the car, and heard a buck elk bugling and saw a coyote stalking squirrels.

The park was busy, especially midday, so we decided to wake up early each day. The park is really beautiful in the early mornings! It’s chilly then (30s-40s), so there’s steam on all the rivers and the lake. We caught a few beautiful sunrises. Brian fished in Yellowstone Lake one morning during sunrise.

Brian bought a 7-day Yellowstone fishing license, and fly fished each day for an hour or two. He fished in Yellowstone Lake, Yellowstone River, and Gibbon River, but had the most luck catching fish in Lamar River in the Lamar Valley. He caught two Yellowstone Cutthroat Trout and safely returned them to the river before a third one broke his hook. Another day he caught three more at another place in the same river where it enters a canyon.

The Lamar Valley is also a great place to see wildlife, and we saw a beautiful pronghorn who came pretty close!

The last day of our visit we went to Lamar Valley and parked near a herd of bison that were resting near the road. We wanted to see them kick up dust and wallow in it, and we saw many of them do it! There were round dusty areas where they must do this pretty often. It’s cute how they kick their legs up and rub their backs in dust, they look so happy! We stayed for over an hour, watching the herd. I felt like we were getting to know them (from a safe distance).

As though wildlife and thousands of geothermic features aren’t enough, Yellowstone has its own Grand Canyon, a 24 mile long, 1,000 feet deep canyon including a gorgeous waterfall.

After viewing it from Artists Point on the South Rim, we visited the North Rim and went to the Brink of the Upper Falls, which is a short hike, and then the Brink of the Lower Falls, which is a short but steep hike. It was fun to get so close to the waterfalls!

Yellowstone is a weird and wonderful place, but it’s hard work! Every evening we came home pretty exhausted. After our 8 days at Fishing Bridge RV Park were up, we didn’t want to leave! So we didn’t. We moved to Mammoth Campground on the northwest side of the park for 4 more days. It is a no-hookup, no reservations, first-come first-serve campground, with picnic tables and fire pits, and frequently elk.

After we moved, we took it a bit easier, and had a couple campfires. Our water heater propane ignition board decided to stop functioning, but thankfully there is an rv repair shop in the park. On our way out of the park we stopped and Brian bought the part and got the water heater working again.

We had a great time at Yellowstone and even after 12 days, which is a long stop for us, it was hard to leave! The steaming, roiling, and erupting features of the park were difficult to capture in photographs, so I made this video.

  1. What a beautiful experience. I can’t wait until we can go to Yellowstone–so much in one place. Your photos are amazing! I visited Sleeping Bear National Lakeshore just yesterday and had the same experience with the drivers–and there wasn’t even any wildlife involved. When we were in Oklahoma at the Wichita Mountains Wildlife Refuge, I saw someone get out of their Class C, walk onto the prairie, and was within six feet of a bison bull taking photos! I know his pictures had to be amazing, but he could have been annihilated in a second. Thank you for sharing your gorgeous photographs–I’m so excited to visit there! Dawn
