Hillock

A hillock, also called a knoll, is a small hill, usually standing apart from a larger group of hills such as a range. Hillocks resemble small mesas or buttes in how they are distributed and in their size, and the source notes that the form occurs often in Great Britain and China. A similar landform in the Scandinavian countries goes by the name kulle or bakke, depending on the country; it forms when glaciers polish down hard crystalline bedrock such as gneiss or granite, leaving a rounded rocky hillock with sparse vegetation. One of the most famous knolls is the grassy knoll in Dealey Plaza in Dallas, Texas, near the point of the assassination of John F. Kennedy. A blind knoll is one that hides the road ahead from drivers, and road signs warn them to slow down.
