Lennox Hills, a range of hills extending east-north-eastward along the middle of the ancient county of Lennox, from the vicinity of Dumbarton to the vicinity of Stirling. It is interrupted, in Strathblane parish, by the valley of the Blane, but is elsewhere continuous. The portion of it WSW of the interruption is called the Kilpatrick Hills, and the portions ENE of the interruption are called the Strathblane, the Killearn, the Fintry, the Gargvunnock, the Campsie, the Kilsyth, and the Dundaff Hills; and all these, with their principal characters and altitudes, are separately noticed. The range has an aggregate length of 23 miles; varies in breadth from 4½ to 9 miles; culminates in Earl's Seat at an altitude of 1894 feet; consists chiefly of various kinds of trap, containing great plenty of rare minerals; and in many parts displays romantic features of glen, ravine, cliff, and basaltic colonnade.
