State Route 28 near Rock Island Dam in Douglas county is closed for four days over Spring Vacation (March 28th to April 2nd) to stabilize a rock slope above the highway. An unstable 300 foot high basalt rock slope has continuously produced falling rock onto SR 28. WSDOT maintenance crews are routinely called to clear hazardous rock fall from the roadway. This project reduces the driving hazard presented by falling rocks on the highway and allows for accommodations for future expansion of SR 28,

contact metamorphism

n.Metamorphism in which the mineralogy and texture of a body of rock are changed by exposure to the pressure and extreme temperature associated with a body of intruding magma. Contact metamorphism often results in the formation of valuable minerals, such as garnet and emery, through the interaction of the hot magma with adjacent rock.VISHAL HIRJI

It is formed when a whole mass of debris is deposited rapidly, with the heavier fragments sinking to the bottom more quickly whilst the finer particles remain suspended in water for some time before finally settling.  This type of deposition is often associated with turbidity current conditions.

The most distinctive feature of sedimentary rocks is the fact that they are usually arranged in layers called beds or strata.  Almost all of these layers were formed horizontally.  Each bed of rock is bounded at the top and bottom by bedding plane which mark breaks in the deposition history and slight changes in the general conditions.

WELL GRADED : has a gradation of particle size that fairly evenly spans the size from the finest to the coarsest.

POOR GRADED : is characterized  by small variation in size. it contains aggregate particles that are almost of the same size.

Open Graded Aggregate

Open graded aggregate contains too much small particles and easy to be disturbed by a hole.

# data[].attributes.body
Uniformly Graded Aggregate

For uniformly graded aggregate, only a few sizes dominate the bulk material. With this grading, the aggregates are not are not effectively packed, and the resulting concrete will be more porous, unless a lot of paste is employed.

# data[].attributes.body
Gap Graded Aggregate

Gap grading is a kind of grading which lacks one or more intermediate size. Gap graded aggregates can make good concrete when the required workability is relatively low. Advantages of gap grading are more economical concrete, use of less cement and lower w/c ratios. When they are used in high workability mixes, segregation may become a problem. The resulting concrete is very stiff and has low workability. An extreme case is no-fines concrete. This concrete is difficult to handle and compact; developing low strength and high permeability.

Well Graded

A well graded soil is a soil that contains particles of a wide range of sizes and has a good representation of all sizes from the No. 4 to No. 200 sieves. A well graded gravel is classified as GW while a well graded sand is classified as SW.

Amethyst is a well known mineral and gemstone. It is the purple variety of the mineral Quartz, and its most valuable and prized variety. Its name derives from the Greek "amethystos", which means "not drunken", as Amethyst in antiquity was thought to ward off drunkenness. The color of some Amethyst specimens from certain localities slowly fade upon prolonged exposure to light. When used as a gemstone, Amethyst is often heat treated to deepen the color, or to transform it into Citrine. Some varieties may also change to a light green color, which is given the trade name "Prasiolite", or "Green Amethyst", as it is more commonly known in the gem trade.

Amethyst is most prevalent as small stubby pyramidal crystals, although several localities such as the Mexican occurrences are well-known for producing elegantly tall prismatic crystals, which are very highly regarded by collectors. Amethyst also forms the internal lining of geodes, some of which can be over 10 feet tall and weighing several tons.
