Cheshire - Physical Geography

Physical Geography

Cheshire covers a boulder clay plain separating the hills of North Wales and the Peak District of Derbyshire (the area is also known as the Cheshire Gap). This was formed following the retreat of ice age glaciers which left the area dotted with kettle holes, locally referred to as meres. The bedrock of this region is almost entirely Triassic sandstone, outcrops of which have long been quarried, notably at Runcorn, providing the distinctive red stone for Liverpool Cathedral and Chester Cathedral.

The eastern half of the county is Upper Triassic Mercia Mudstone laid down with large salt deposits which were mined for hundreds of years around Northwich. Separating this area from Lower Triassic Sherwood Sandstone to the west is a prominent sandstone ridge known as the Mid Cheshire Ridge. A 55-kilometre (34 mi) footpath, the Sandstone Trail, follows this ridge from Frodsham to Whitchurch passing Delamere Forest, Beeston Castle and earlier Iron Age forts.

The highest point in Cheshire is Shining Tor on the Derbyshire/Cheshire border between Macclesfield and Buxton, at 559 metres (1,834 ft) above sea level. Prior to county boundary alterations in 1974, the county top was Black Hill (582 m (1,909 ft)) near Crowden in the far east of the historic county on the border with the West Riding of Yorkshire. Black Hill is now the highest point in West Yorkshire.

Famous quotes containing the words physical and/or geography:

    The entire construct of the “medical model” of “mental illness”Mwhat is it but an analogy? Between physical medicine and psychiatry: the mind is said to be subject to disease in the same manner as the body. But whereas in physical medicine there are verifiable physiological proofs—in damaged or affected tissue, bacteria, inflammation, cellular irregularity—in mental illness alleged socially unacceptable behavior is taken as a symptom, even as proof, of pathology.
    Kate Millett (b. 1934)

    Ktaadn, near which we were to pass the next day, is said to mean “Highest Land.” So much geography is there in their names.
    Henry David Thoreau (1817–1862)
