Geography ISP: Interlocking Spurs
1. An Interlocking Spur is a physical feature which consists of: a valley in the form of the letter V, a river bank (the part of a river where the land begins and where the land slowly gets higher and higher until reaching water level), a source (the first place in a river where water begins to flow), a channel(the outline of a shallow narrow body of water) and spurs.
3. The formation of an Interlocking Spur takes a very long time due to the many stages it must undergo to finally become an Interlocking Spur. It begins as flowing water which gradually begins to erode the ground as it moves. At the same time rain causes the sides of the valley to begin eroding in a downwards fashion. In an attempt to find a path consisting of more resistant rocks, it begins to form small hills on the sides of the valley. As the sides of the valley continue to erode, earth and rocks fall into the stream. They then become deposited
outside of the bends. This vertical erosion causes the formation of the narrow spurs, because the water is moving faster causing the interlocking spurs to be formed. Over time the spurs become more and more refined, so much so that it almost looks like a long zipper.
5. Examples of Interlocking Spurs:
Interlocking spurs at Ashes Hollow, tributary to the River Severn
Interlocking spurs looking up Oxendale Beck, tributary to the River Brathay in Lake District, Cumbria
Interlocking spurs on a tributary of the Yangtse
6. Interlocking Spurs have a somewhat limited use for humans. We are unable to draw electricity from them due to the overall weakness of the current. This however is irrelevant to
scientists and researchers who can use them in an effort to find out more about our past. The most common use of interlocking spurs are for tourists. Many people come from all over to the beauty of these geographical marvels.
