Yellowstone National Park Geography Quiz: Quick Study Notes
Yellowstone National Park is a geological marvel and an ecological hotspot, spanning parts of Wyoming, Montana, and Idaho. Its unique geography is defined by a massive supervolcano, which fuels its iconic geysers and hot springs. The park is also home to significant river systems, vast forests, and a diverse array of wildlife, all shaped by its high-altitude, continental climate. Exploring Yellowstone’s natural features offers a profound understanding of Earth’s dynamic processes.
Key Geographical Aspects
Yellowstone sits atop a supervolcano, with its vast caldera defining the park’s topography and fueling its geothermal features.
Home to over half of the world’s geysers, including Old Faithful, and thousands of hot springs, fumaroles, and mudpots.
The Yellowstone River flows through the park, creating a grand canyon, and Yellowstone Lake is North America’s largest high-elevation lake.
A crucial habitat for bison, grizzly bears, wolves, elk, and many other species within the vast Greater Yellowstone Ecosystem.
Key Takeaways

Frequently Asked Questions about Yellowstone Geography
What is a caldera and how does it relate to Yellowstone?
A caldera is a large, basin-shaped depression formed when the roof of a magma chamber collapses after an eruption. Yellowstone National Park lies on top of an active supervolcano, and its vast caldera, formed by three massive eruptions over 2 million years, is responsible for the park’s intense geothermal activity, including geysers and hot springs.
What are the most famous hydrothermal features in Yellowstone?
Yellowstone is famous for Old Faithful, a highly predictable geyser. Other notable features include Grand Prismatic Spring, the largest hot spring in the United States, and Mammoth Hot Springs, known for its travertine terraces, as well as the powerful Steamboat Geyser, the world’s tallest active geyser.
Which major river flows through Yellowstone National Park?
The Yellowstone River is the primary river flowing through the park. It originates in the Absaroka Mountains, flows north through Yellowstone Lake, and then carves out the spectacular Grand Canyon of the Yellowstone, featuring impressive waterfalls like the Upper and Lower Falls.
What kind of wildlife can be found in Yellowstone?
Yellowstone is a sanctuary for diverse wildlife. Iconic species include large herds of bison (American buffalo), elk, grizzly bears, black bears, wolves (reintroduced in the 1990s), moose, pronghorn, and numerous bird species, all thriving within its varied ecosystems.
What is the climate like in Yellowstone National Park?
Yellowstone experiences a continental to subalpine climate, largely influenced by its high elevation. Winters are long, very cold, and receive heavy snowfall, making many roads impassable. Summers are short and mild, with temperatures ranging from 60s to 70s Fahrenheit during the day, but nights can be cool, even freezing at higher elevations.
