Cirque glaciers are found in mountainous regions, typically in high altitudes where there is sufficient snowfall to accumulate and form ice. They are often found in:

* The Alps: The European Alps are a classic example, with numerous cirques carved into the mountains.

* The Himalayas: This mountain range is home to some of the world's largest and most impressive cirques.

* The Rocky Mountains: The Rocky Mountains of North America also boast many cirques, particularly in the Canadian Rockies.

* The Andes Mountains: The Andes in South America feature extensive glaciation, including numerous cirques.

* The Caucasus Mountains: This mountain range in Eurasia has a number of cirques formed by past glaciation.

* New Zealand: The Southern Alps of New Zealand are known for their stunning glacial landscapes, including cirques.

* Antarctica: While not technically "mountains," Antarctica has extensive areas of ice sheets that exhibit cirque-like features.

It's important to note that cirques can form in other areas with sufficient glacial activity, even if they're not traditionally considered "mountainous." For instance, you can find cirques in high-altitude areas of Scandinavia, northern Scotland, and even some coastal areas of Alaska where glaciers once extended further down.
