“A Full Day”
June 19, 2026 - 0 Comments
We started our day off with a walk around Mammoth Terraces, where hot springs were creating small puddles of water and mini waterfalls along the travertine rocks. Small rills were forming in the soft travertine that are similar to columns and stalactites in a cave.

We measured the water temperature from a safe distance with an infrared thermometer, and recorded values of 170 degrees Fahrenheit. For reference, hot tubs are typically around 102-107 degrees Fahrenheit. Although it’s tempting, one should never touch this water, because it would lead to severe skin burns and even death.

During this hike, we found a beautiful, light-blue, bubbling puddle of water near the Narrow Gauge Terrace to inspire us while nature journaling. We observed an elk grazing and a mule-deer nursing two speckled fawns. We also practiced identifying Douglas fir trees, Rocky Mountain junipers, and limber pines. Mammoth Terraces are a must-see for anyone interested in geology or biology, and we all left the hike feeling energized for our next adventure.
A poem from the terraces:
A rock like hot snow, deposited by water’s flow.
Thermophilic critters coat the bank, elk tracks in the soft rock sank.
Mysterious terrace of heat and slime, shifting and changing throughout time.
Rolling hills all around, flora and fauna still abound.
A timeless yet fleeting world, from Earth’s depths is hurled.

After lunch we headed out with Ranger Avery from the park’s education department to do a pika survey. After scrambling over and around massive rocks, we spotted one pika on the trail and counted several more when we heard their “eep” calls!
On our evening wildlife watching drive to Cooke City we observed large herds of bison cows with their rusty-colored calves along the river. We ate amazing pizza at Miners Saloon and headed back towards Mammoth. On the way, we were stopped by bison crossing the road and were able to observe two speckled, juvenile bald eagles. We also saw nature in action as a coyote carried off a dead baby calf the same size as itself for its dinner.
