historic county of west-central Scotland, northwest and northeast of Glasgow. It comprises two sections: the main body of the county in the west, extending along the north bank of the River Clyde from the outskirts of Glasgow to Loch Long, and a smaller detached area in the east surrounding the towns of Kirkintilloch and Cumbernauld. The larger western section is an area of steep hills descending to the shores of Loch Lomond, the River Clyde, Gare Loch, and Loch Long. The highest of these, northwest of Loch Lomond, is Ben Vorlich, with an elevation of 3,092 feet (942 metres). The eastern section lies on the lowland plain that extends between the River Clyde and the Firth of Forth. The council area of West Dunbartonshire lies entirely within the historic county of Dunbartonshire, as do parts of the council areas of North Lanarkshire, East Dunbartonshire, and Argyll and Bute.
