Knoll

We used to play over by that grassy knoll.

Tom was on the grassy knoll with a rifle.

On ascending the knoll near the house, from which all the neighbouring moors were visible, they not only could see no signs of the missing favourite, but they perceived something which warned them that they were in the presence of a tragedy.

On February 4, 1960, when we landed the aircraft within 100 yards of the 16 wolves on Intermediate Lake, the animals eventually scattered into the woods. A few minutes later we heard some howling, which soon increased in volume until the entire pack seemed to be involved. The whining, yelping, and howling (much of which was high-pitched) continued for about 30 seconds and then gradually diminished; a few single howls were emitted after the chorus had subsided. Tracks later showed that the wolves had assembled on a small knoll, where most of the howling probably originated.

His guide said not another word until they had traveled for half an hour along a twisting path and stood at last on the bald summit of a knoll from which they could look down upon a number of lights twinkling dimly a quarter of a mile away.

On knoll or hillock rears his crest, / Lonely and huge, the giant oak.

In the northern hemisphere, June 21 has the most daylight hours. Pack a picnic—a chilled bottle of Sancerre, cheese, olives, and a nice baguette—and hit the grassy knoll.

If ever been where bells have knoll'd to church.

For a departed being's soul / The death hymn peals, and the hollow bells knoll: [...]

[A]ll that night I heard / The heavy clocks knolling the drowsy hours.
