The interior of the island is hilly, though not mountainous, with conifer plantations and some uncultivated land, particularly in the north.Bute straddles the divide between highland and lowland Scotland with the Highland Boundary Fault cutting NNE-SSW through the island between Rothesay Bay and Scalpsie Bay.To the north of this line are metamorphosed sandstones and mudstones (i.e.Higher marine platforms with partial cover of sand and gravel are recognised further inland, dating from earlier parts of the Devensian ice age.Till derived from the ice age is widespread inland while isolated peat deposits particularly in the north. Small areas of blown sand are to be found landward of some sandy bays.Hamlets on the western side of the island include Straad, around St. In the north, Bute is separated from the Cowal peninsula by the Kyles of Bute.The northern part of the island is more sparsely populated, and the ferry terminal at Rhubodach connects the island to the mainland at Colintraive by the smaller of the island's two ferries.Loch Fad is Bute's largest body of freshwater and runs along the fault line.The western side of Bute is known for its beaches, many of which enjoy fine views over the Sound of Bute towards Arran and Bute's smaller satellite island Inchmarnock.Associated with the latter are Carboniferous extrusive igneous rocks, mainly lavas and tuffs of the Clyde Plateau Volcanic Formation.These occur north of Ascog, northeast of Scalpsie and south of Kilchattan Bay.Discover the perfect gift or treat yourself with our range of books, clothes and gifts.
