Emerald Pool

Emerald Pool (Yosemite National Park)

Emerald Pool is a small stream pool in the Merced River above Vernal Fall in Yosemite National Park. It is named for its deep green color, which is caused by algae living on the rocks at the bottom of the pool. In the summertime during diminished water flow, the Silver Apron is frequently used by hikers as a water slide. Swimming or wading in the Emerald Pool or entering the Silver Apron is prohibited by the National Park Service since waders or swimmers have been swept over Vernal Fall and killed, and people sliding down Silver Apron risk collision with hidden rocks at its lower end. This prohibition is clearly marked with signs.

Emerald Pool (Yuba River)

Emerald Pool is a pool in California along the Yuba River. 39.3213°N 120.6558°W The South Yuba River flows down a 60 feet (18 m) waterfall into a sheer rock canyon with two pools. The walls around the first pool measure from around 30 feet (9.1 m) to 80 feet (24 m) in height with a length of around 50 metres (160 ft) and width of around 30 metres (98 ft). The crystal-clear water is deep, 27 feet (8.2 m) near the middle of the pool, and many people jump off the cliffs for enjoyment. A second pool nearby is nearly as large. Despite the cool water temperature it is a popular swimming spot, particularly among young adults.

Emerald

Emerald is a gemstone and a variety of the mineral beryl (Be3Al2(SiO3)6) colored green by trace amounts of chromium or sometimes vanadium. Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds have many inclusions, so their toughness is classified as poor. Emerald is a cyclosilicate. It occurs mainly in association with quartz, muscovite, albite, mica schist, Pyrite schorl, microcline, fluorite, smoky quartz and elbaite.

Shades of green

Varieties of the color green may differ in hue, chroma or lightness, or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a green or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below.
