picture info	Cobble (geology) A cobble (sometimes a cobblestone) is a clast of rock defined on the Udden–Wentworth scale as having a particle size of , larger than a pebble and smaller than a boulder. Other scales define a cobble's size differently. A rock made predominantly of cobbles is termed a conglomerate. Cobblestone is a building material based on cobbles. Etymology Cobbles, also called cobblestones, derive their name from the word cob, meaning a rounded lump. The term is further related to the German ', meaning ''head''. Chester Wentworth referred to cobbles as ''cobble bowlders'' in his 1922 paper that would become the basis for the Udden–Wentworth scale. Classifications Within the widely used Krumbein phi scale of grain sizes, cobbles are defined as clasts of rock ranging from −6 to −8 φ. This classification corresponds with the Udden–Wentworth size scale which defines cobbles as clasts with diameters from . On this scale, cobbles are larger than pebbles which measure in diam ...

picture info	Cobblestone Cobblestone is a natural building material based on cobble-sized stones, and is used for pavement roads, streets, and buildings. Setts, also called Belgian blocks, are often casually referred to as "cobbles", although a sett is distinct from a cobblestone by being quarried or shaped to a regular form, whereas cobblestone is generally of a naturally occurring form and is less uniform in size. Use in roading Cobblestones are typically either set in sand or similar material, or are bound together with mortar. Paving with cobblestones allows a road to be heavily used all year long. It prevents the build-up of ruts often found in dirt roads. It has the additional advantage of immediately draining water, and not getting muddy in wet weather or dusty in dry weather. Shod horses are also able to get better traction on stone cobbles, pitches or setts than tarmac or asphalt. The fact that carriage wheels, horse hooves and even modern automobiles make a lot of noise when rolli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Hammerstone In archaeology, a hammerstone is a hard cobble used to strike off lithic flakes from a lump of tool stone during the process of lithic reduction. The hammerstone is a rather universal stone tool which appeared early in most regions of the world including Europe, India and North America. This technology was of major importance to prehistoric cultures before the age of metalworking. Materials A hammerstone is made of a material such as sandstone, limestone or quartzite, is often ovoid in shape (to fit the human hand better), and develops telltale battering marks on one or both ends. In archaeological recovery, hammerstones are often found in association with other stone tool artifacts, debitage and/or objects of the hammer such as ore. The modern use of hammerstones is now mostly limited to flintknappers and others who wish to develop a better understanding of how stone tools were made. Usage Hammerstones are or were used to produce flakes and hand axes as well as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Tyringham Cobble Tyringham Cobble is a open space reservation located in Tyringham, Massachusetts on 411 m (1,348 ft) Cobble Hill in The Berkshires. It is managed by The Trustees of Reservations, a non-profit conservation organization, and is notable for its scenic views over the rural landscape of Tyringham Valley from rocky ledges and open fields. The reservation consists of the hill and surrounding agricultural and pasture land. In 2008, part of the 2,175 mile (3,500 km) Appalachian Trail was routed over the summit ledges. History ''Cobble'' is derived from the German word ''kobel'' or ''koble'', usually applied to small, rocky, rounded and exposed hills. Cobble Hill belongs to the largest pre-Cambrian geologic territory in Massachusetts. Studies of the hill by geologist Daniel Clark in 1895 showed that rock strata on the bottom of the hill was younger than strata on the top, leading him to conclude, incorrectly, that the hill had "broken off a nearby mountain and flipped over ...

	Dorothy Sue Cobble Dorothy Sue Cobble (June 28, 1949) is an American historian, and a specialist in the historical study of work, social movements, and feminism in the United States and worldwide. She is currently a Distinguished Professor at Rutgers University, holding dual appointments in the Departments of Labor Studies and History since 1986. Her book ''The Other Women’s Movement'' (2005) coined the term labor feminism. Early life and education Cobble grew up in the South, before receiving her B.A. from the University of California, Berkeley in 1972. She worked briefly as a trade union stevedore in the mid-1970s before earning her Ph.D. in history from Stanford University in 1986. A student of Carl Degler, she became a leading historian of women's labor movements. Career Cobble's first book ''Dishing It Out: Waitresses and Their Unions in the Twentieth Century'' (1991) was among the earliest studies
