Opal Opal is the most rare and valuable gemstone in the entire world. Every single opal is different and unique. You will never be able to find an opal that is exactly the same as another opal. They are found all over the world. All opal gemstones are considered gemstones‚ and not semi precious stones‚ because of its quality and rarity. Opals are usually opaque but can sometimes be translucent or even transparent. On Moh’s Scale‚ the opal’s hardness is 5.5 – 6.5. This is relatively soft‚ so opal

According to Ron’s notes his excavation took place on the northern extension of Mount Moriah. The north side of Mount Moriah is a very Stoney and dry area; certain parts of the mountain have lowered the ground to that of a trench. This side is also referred to as Skull Mountain or Golgotha; it was at this side of the mountain that Jesus was crucified. This side of the mountain is also where Jesus was buried in the “garden tomb”. Ron believed that the escarpment of this side of the mountain was

starts at the source of the rivers channel. The upper course of the river is shallow and has a narrow river channel due to vertical erosion caused by hydraulic action and corrosion. It also has an uneven steep river bed due its bedload as it is large boulders as they have rough edges. This then gets transported through the upper part of the river by traction. In addition some of the bedload also gets transported by suspension and little in siltation. As the river flows through the upper course of its

downstream increases when there are more streams feeding the main stream. The load of a river is the total amount of material carried or transported by a river. The bedload is the load transported along the bed of the river‚ mainly pebbles‚ gravel‚ boulders and coarse materials. These particles will bounce along the river’s bed and the river’s load is derived from its bed and banks wash down on its valley sides and surface creep. The river‚ when loaded with debris‚ has a lower velocity‚ hence there

River Compact of 1922 – finally cleared the way for the dam to be built. President Calvin Coolidge 30th President of the United States authorized the Boulder Canyon Project in 1928.

The next step was to figure out how to pay for the dam project‚ the Federal Government Approved $177‚000‚000. The decision

and fine sands). Large-calibre material can be moved when velocity increases. Because the maximum particle mass that can be moved increases with the sixth power of velocity‚ when discharge levels are high‚ for example during a flood‚ much larger boulders can be moved. The Hjulström curve illustrates the relationship between velocity and competence. It shows the velocities at which sediment will normally be eroded‚ transported or deposited. The mean or critical erosion velocity (also known as entertainment
