The Inkwells (Marin County)
The Inkwells (also known as The Ink Wells) are 2 deep natural swimming pools in Lagunitas Creek, in Marin County, California. The upper Inkwell is also known as "Shafters", named after the former railroad bridge that bore its name nearby, whereas the lower Inkwell is simply known as "Inkwell" or "Hole" because it is deeper and darker. Together, they are known as "The Inkwells". They are a common swimming spot in summer, despite failing to meet current water quality standards due to high levels of coliform. The Inkwells are accessible by car as well as public transit, with a Marin Transit bus stop being less than a mile away. The Inkwells Bridge, which runs above the inkwells, is part of the Bay Area Ridge Trail. It also carries pipes that bring water from nearby Kent Lake and the nearby Nicasio Reservoir Nicasio Reservoir is a shallow, artificial reservoir in the Nicasio Valley region of Marin County, California, United States. It covers and sits in a drainage basin. It was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lagunitas Creek
Lagunitas Creek is a -longU.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed December 27, 2017 northward-flowing stream in Marin County, California. It is critically important to the largest spawning runs of endangered coho salmon (''Oncorhynchus kisutch'') in the Central California Coast Coho salmon Evolutionary Significant Unit (CCC ESU). The stream's headwaters begin on the northern slopes of Mount Tamalpais in the Coast Range and terminate in southeast Tomales Bay, northwest of Point Reyes Station, California. Lagunitas Creek feeds several reservoirs on Mt. Tamalpais that supply a major portion of the county's drinking water. History To the Coast Miwok the stream was known as Tokelalume, then by the Spanish as Arroyo de San Geronimo, then Daniels creek. Now the "San Geronimo" survives only as the San Geronimo Creek tributary. The modern name, Lagunitas Creek, is derived from the several "lagunitas" (Spanish for "littl ...

Coliform Bacteria
Coliform bacteria are defined as either motile or non-motile Gram-negative non- spore forming Bacilli that possess β-galactosidase to produce acids and gases under their optimal growth temperature of 35-37°C. They can be aerobes or facultative aerobes, and are a commonly used indicator of low sanitary quality of foods, milk, and water. Coliforms can be found in the aquatic environment, in soil and on vegetation; they are universally present in large numbers in the feces of warm-blooded animals as they are known to inhabit the gastrointestinal system. While coliform bacteria are not normally causes of serious illness, they are easy to culture, and their presence is used to infer that other pathogenic organisms of fecal origin may be present in a sample, or that said sample is not safe to consume. Such pathogens include disease-causing bacteria, viruses, or protozoa and many multicellular parasites. Genera Typical genera include: * '' Citrobacter ''are peritrichous facultative ...

Bay Area Ridge Trail
The Bay Area Ridge Trail (Ridge Trail) is a planned multi-use trail along the hill and mountain ridgelines ringing the San Francisco Bay Area, in Northern California. Currently, have been established. When complete, the trail will connect over 75 parks and open spaces. The trail is being designed to provide access for hikers, runners, mountain bicyclists, and equestrians. It will be accessible through trailheads near major population centers, while the trail will extend into more remote areas. The first trail section was dedicated on May 13, 1989. History William Penn Mott Jr., the twelfth director of the National Park Service, is credited with sparking the idea for the Ridge Trail in a speech he gave in March 1987 at a state parks and recreation conference. While working for the East Bay Regional Park District in the 1960s, Mott's office was on a ridgeline in the East Bay, and the views from the office inspired his vision of a hill-and-ridge trail encircling the Bay and lin ...

Nicasio Reservoir
Nicasio Reservoir is a shallow, artificial reservoir in the Nicasio Valley region of Marin County, California, United States. It covers and sits in a drainage basin. It was created by the construction of Seeger Dam on the Nicasio Creek in 1961. Seeger Dam is a tall, long earthen dam owned by the Marin Municipal Water District. Controversy The construction in the dam aroused much controversy among longtime residents of the area. The Water District forced the displacement of many farms, including the McIsaac family farm and the Tomasini Ranch, on which the majority of the reservoir sits. The controversy stems from the fact the water from the reservoir is rarely used by the Water District, that the broad and shallow nature of the reservoir leads to quick evaporation, and that the dam has blocked valuable spawning areas for endangered coho salmon and threatened steelhead trout. Construction of Seeger Dam wiped out the salmon population in Nicasio Creek. The District briefly at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Pools
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word '' physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-So ...
