What is "cirques"

Usage examples of "cirques".

The moths aggregated in glacial cirques on talus right below steeper headwalls.

The aggregations of the cutworm moths, and so the feeding grounds of the bears, were usually at the head of the cirques below the massifs.

The temperature was far below zero and they were faced with a breath-takingly beautiful but hazardous sight as clouds closed in almost all views below them, even of the slight dips, valleys, and cirques, leaving only the points of the highest peaks popping up into a brilliant, almost blinding sun.

And then the night after that, after some of them had spent the day out fell running, exploring high basins in his quest to see as much of the land as he could, they might stay out to sleep in a little survival tent, camping in one of the high cirques east of the city, heating a meal in the dusk as stars popped out everywhere in the purple sky, and the alpine flowers faded away into the basin of rock that held them all, as if in the palm of a giant hand.

There were high basins that resembled cirques, and high valleys with the classic U-shape of glacial valleys, and some dome-and-wall configurations that might have been the result of glacial plucking.
