The Black Hole- The Glory Whole

Part of the Monticello Dam, this giant funnel drains overflow water from Lake Berryessa past the dam to the river below.

Lake Berryessa is the largest lake in Napa County, California. This reservoir is formed by the Monticello Dam, which provides water and hydroelectricity to the North Bay region of the San Francisco Bay Area.
The lake was named for the first European settlers in the Berryessa Valley, José Jesús and Sexto "Sisto" Berrelleza (a Basque surname, Anglicized to Berreyesa then later respelled Berryessa), who were granted Rancho Las Putas in 1843.
Prior to its inundation, the valley was an agricultural region, whose soils were considered among the finest in the country. The main town in the valley, Monticello, was abandoned in order to construct the reservoir. This abandonment was chronicled by the photographers Dorothea Lange and Pirkle Jones in their book Death of a Valley. Construction of Monticello Dam was begun in 1953,^[3] and the reservoir filled by 1963, creating what at the time was the second-largest reservoir in California after Shasta Lake.
The lake is heavily used for recreational purposes and encompases over 20,000 acres (80 km²) when full. The reservoir is approximately 15.5 miles (25 km) long, but only 3 miles (5 km) wide. It has approximately 165 miles (265 km) of shoreline. It has a seaplane landing area that is open to the public. One of the larger islands supported a small plane landing area, but was closed down in the early 1970s after the FAA issued a safety report.
The area was also the site of one of the infamous Zodiac Killer's murders.

Rocks Rocks Rocks

Igneous
The oldest type of all rocks is the igneous rock (IG nee us). The word "igneous" comes from a Greek word for fire. Deep inside the earth, the temperature is very high and the minerals there are in liquid form called magma. As the magma pushes towards the earth's surface, it starts to cool and turns into solid igneous rock.

Sedimentary
The earth's surface is constantly being eroded. This means that rocks are broken up into smaller pieces by weathering agents such as wind, water, and ice. These small pieces of rock turn into pebbles, gravel, sand, and clay. They tumble down rivers and streams. These pieces settle in a new place and begin to pile up and the sediments form flat layers. Over a long period of time, the pieces become pressed together and form solid rock called sedimentary rock. Most sedimentary rocks form under water. Most of the earth has been covered by water some time in the past. 70% of the earth is covered by water now. So sedimentary rocks are common all over the world. Sedimentary rocks are often rich in fossils.

Metamorphic
Heat and pressure can change many things. They can even change rocks. The name for rocks that has been changed is metamorphic (met uh MOR fik) rocks. Metamorphic comes from Greek words meaning "change" and "form".
Metamorphic rocks form deep in the earth where high temperature, great pressure, and chemical reactions cause one type of rock to change into another type of rock. Metamorphic rocks begin to form at 12-16 kilometers beneath the earth's surface. They begin changing at temperatures of 100 degrees Celsius to 800 degrees Celsius. If you squeeze and heat a rock for a few million years, it can turn into a new kind of rock.

All igneous rocks do not cool the same way. That is why they do not look all the same. Some cool slowly, deep under the earth's surface. These are called intrusive igneous rocks. The slow cooling formed rocks with large crystals. Granite is an example of a rock that cooled slowly and has large crystals.

To the Extreme- Psychrophiles

Psychrophiles are commonly described as microorganisms which exhibit a growth temperature optimum of 15°C and lower. The recent discovery of cold-tolerant microorganisms in glaciated and permanently frozen environments has broadened the known range of environmental conditions which support microbial life. Psychrophilic bacteria belong to four phylogenetic groups, the alpha and gamma subdivisions of the Proteobacteria, the Flexibacter-Bacteroides-Cytophaga phylum and the gram-positive branch. Isolates from cold environments include Arthrobacter sp., Psychrobacter sp., and members of the genera Halomonas, Pseudomonas, Hyphomonas, and Sphingomonas
