Emerald Pool is the name of several locations.
Emerald Pool is a small, shallow lake, with an area of less than one acre. It is located about 80 meters 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 (a smooth granite slope over which the Merced River flows into the Emerald Pool) is frequently (albeit illegally) 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 the Silver Apron risk collision with hidden rocks at its lower end. [2] [3] This prohibition is clearly marked with signs.

There also is an Emerald Pools destination in California along the Yuba River. [4] 39°19′17″N120°39′21″W / 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.[ citation needed ]
Emerald Pool, a hot spring named for its emerald green color, is one of the main attractions at Black Sand Basin in Yellowstone National Park. Its temperature is 154.6 °F and its dimensions are 27x38 feet with a depth of 25 feet. The color is due to growth of yellow bacteria and algae. Cooling, the result of objects thrown into the pool and natural debris, has affected the growth of the bacteria and algae, making the pool appear orange and brown around the edges. [5]
Other locations named Emerald Pool are in Morne Trois Pitons National Park in Dominica, and in Zion National Park in Utah.

Yosemite Valley is a glacial valley in Yosemite National Park in the western Sierra Nevada mountains of Central California. The valley is about 7.5 mi (12.1 km) long and 3,000–3,500 ft (910–1,070 m) deep, surrounded by high granite summits such as Half Dome and El Capitan, and densely forested with pines. The valley is drained by the Merced River, and a multitude of streams and waterfalls flow into it, including Tenaya, Illilouette, Yosemite and Bridalveil Creeks. Yosemite Falls is the highest waterfall in North America and is a big attraction especially in the spring, when the water flow is at its peak. The valley is renowned for its natural environment and is regarded as the centerpiece of Yosemite National Park.
Tuolumne Meadows is a gentle, dome-studded, sub-alpine meadow area along the Tuolumne River in the eastern section of Yosemite National Park in the United States. Its approximate location is 37°52.5′N119°21′W. Its approximate elevation is 8,619 feet (2,627 m). The term Tuolumne Meadows is also often used to describe a large portion of the Yosemite high country around the meadows, especially in context of rock climbing.
The Mist Trail is one of the most popular short hikes in Yosemite National Park, California, USA. The steep hike follows the Merced River, starting at Happy Isles in Yosemite Valley, past Vernal Fall and Emerald Pool, to Nevada Fall.
Nevada Fall is a 594-foot (181 m) high waterfall on the Merced River in Yosemite National Park, California. It is located below the granite dome, Liberty Cap, at the west end of Little Yosemite Valley. The waterfall is widely recognized by its "bent" shape, in which the water free-falls for roughly the first third of its length to a steep slick-rock slope. This mid-fall impact of the water on the cliff face creates a turbulent, whitewater appearance in the fall and produces a great deal of mist which covers a wide radius, which led to its current name.
Glacier Point is a viewpoint above Yosemite Valley in the U.S. state of California. It is located on the south wall of Yosemite Valley at an elevation of 7,214 feet (2,199 m), 3,200 feet (980 m) above Curry Village. The point offers a superb view of several of Yosemite National Park's well-known landmarks, including Yosemite Valley, Yosemite Falls, Half Dome, Vernal Fall, Nevada Fall, and Clouds Rest. Between 1872 and 1968, it was the site of the Yosemite Firefall.
Vernal pools, also called vernal ponds or ephemeral pools, are seasonal pools of water that provide habitat for distinctive plants and animals. They are considered to be a distinctive type of wetland usually devoid of fish, and thus allow the safe development of natal amphibian and insect species unable to withstand competition or predation by fish. Certain tropical fish lineages have however adapted to this habitat specifically.
Vernal Fall is a 317-foot (96.6 m) waterfall on the Merced River just downstream of Nevada Fall in Yosemite National Park, California. Like its upstream neighbor, Vernal Fall is clearly visible at a distance, from Glacier Point, as well as close up, along the Mist Trail. The waterfall flows all year long, although by the end of summer it is substantially reduced in volume and can split into multiple strands, rather than a single curtain of water.
Emerald Spring is a hot spring located in Norris Geyser Basin of Yellowstone National Park.
Sierra Point is a point located in Yosemite National Park at the eastern end of the valley, below Grizzly Peak. The trail used to be quite popular, but was closed due to a rock slide in the 1970s. This was John Muir's favorite trail. While a portion of the trail is still missing, it is still possible to reach the point. In fact, the trail is only 0.7 miles (1.1 km) long and about 1,000 feet (300 m) off the valley floor. This hike should not be attempted by beginning hikers due to the difficulty of the missing portions of the trail. In fact, the National Park Service does not recommend that anyone take this trail. Despite this warning, many people still reach the point each year as it is easily accessible from the Vernal Fall trail in Happy Isles, and still has the original railing at the top. It is popular in part because it is the only point in the valley from which four waterfalls can be seen from one vantage point: Vernal Fall, Nevada Fall, Yosemite Falls, and Illilouette Fall.
Black Pool is a hot spring in the West Thumb Geyser Basin of Yellowstone National Park in the United States.
The Santa Rosa Plateau is an upland plateau and southeastern extension of the Santa Ana Mountains in Riverside County, southern California. It is bounded by the rapidly urbanizing Inland Empire cities of Murrieta and Temecula to the northeast and southeast, respectively.
Economic Geyser is a geyser in the Upper Geyser Basin of Yellowstone National Park in the United States.
Swimming pool sanitation is the process of ensuring healthy conditions in swimming pools. Proper sanitation is needed to maintain the visual clarity of water and to prevent the transmission of infectious waterborne diseases.
Little Yosemite Valley is a smaller glacial valley upstream in the Merced River drainage from the Yosemite Valley in Yosemite National Park. The Merced River meanders through the 3.5 mi (5.6 km) long flat valley, draining out over Nevada Fall and Vernal Fall before emptying into the main Yosemite Valley. It can be reached by a day hike from the main valley, and is the most popular area in the Yosemite Wilderness. The Valley provides access to nearby destinations such as the back side of Half Dome, Clouds Rest and the High Sierra Camp at Merced Lake.
Linderiella occidentalis is a species of fairy shrimp native to California. It is a small crustacean in the family Chirocephalidae family. It has a delicate elongated body, large stalked compound eyes, no carapace, and eleven pairs of swimming legs. It glides gracefully upside down, swimming by beating its legs in a complex, wavelike movement that passes from front to back. Like other fairy shrimp, L. occidentalis feeds on algae, bacteria, protozoa, rotifers and detritus.
The conservancy fairy shrimp is a small crustacean in the family Branchinectidae. It ranges in size from about 1.25 centimetres (0.49 in) to 2.5 centimetres (0.98 in) long. Fairy shrimp are aquatic species in the order Anostraca. They have delicate elongate bodies, large stalked compound eyes, no carapaces, and eleven pairs of swimming legs. They glide gracefully upside down, swimming by beating their legs in a complex, wavelike movement that passes from front to back. Fairy shrimp feed on algae, bacteria, protozoa, rotifers and detritus. This species is endemic to California in the United States.
The vernal pool fairy shrimp, Branchinecta lynchi, is a species of freshwater crustacean in the family Branchinectidae. It is endemic to the U.S. states of Oregon and California, living in vernal pools as well as non-vernal pool habitat. They range in size from 0.43 to 0.98 inches long. Vernal pool fairy shrimp are listed as a vulnerable species on the IUCN Red List, and has been listed as Federally Threatened species since 1994.
Pink algae is a growth of pink, slimey bacterial matter which can sometimes occur in pools and laboratory equipment. The name is a misnomer, because pink algae is not a true algae but is actually caused by a bacterium in the genus Methylobacterium. The color of the bacterial growth comes from pigments within its cells. The slime formed around the bacteria provides it with a relatively high level of protection from external threats. Like other species in its genus, pink algae is a methane consuming bacterium. It has an affinity for the matrix of PVC plastics, and will attach itself to both the inside and the outside of PVC materials inside of the pool. Pink algae infestation in a pool often occurs alongside an infestation of white water mold.
Emerald Pools Recreational Area is a series of swimming holes and short hiking trails located on Jordan Creek and the South Yuba River in Nevada County, California and the Tahoe National Forest. Located downstream of Lake Spaulding, Emerald Pools sits at approximately 4,200 ft above sea level. The Upper Pools are situated where Jordan Creek and the South Yuba River converge, near the former settlement of Langs, California. The Lower Pools are located 0.75 miles (1.2 km) further downstream of the South Yuba River towards Box Canyon at the base of a waterfall.
The Panorama Trail is a marked hiking trail in Yosemite National Park that descends along the south wall of Yosemite Valley from Glacier Point, past several major waterfalls, to Happy Isles. The trail derives its name from the panoramic vistas visible along the route, most notably Panorama Point.
