Agkistrodon contortrix mokasen is a venomous pit viper subspecies found in the eastern United States.
The northern copperhead grows to an average length of 61-91 cm (24-36 in), with a maximum of 135 cm (53 in).
The dorsal scales are weakly keeled. The anal plate is single. The subcaudals are single, at least anteriorly.
The color pattern consists of an hourglass pattern that runs the length of the body. From above, a series of dark chestnut crossbands look narrow in the center and wider on the sides. Between the crossbands, small dark spots are often present. There are dark rounded spots at the sides of the belly. The head is a copper-red color. Juvenile specimens are lighter in color, have a yellow tail tip, and a narrow dark line that runs through the eye that divides the darker head from the lighter colored labial scales.

Copper is a reddish brown color that resembles the metal copper.
The first recorded use of copper as a color name in English was in 1594.
At right is displayed pale tone of copper that is called copper in Crayola crayons. This color was formulated by Crayola in 1903.
At right is displayed the color copper red.
The first recorded use of copper red as a color name in English was in 1590.

At right is displayed the color copper penny.
Copper penny is one of the colors in the special set of metallic Crayola crayons called Silver Swirls, the colors of which were formulated by Crayola in 1990.
At right is displayed the color copper rose.
The first recorded use of copper rose as a color name in English was in 1928.
Copper was a DikuMUD based MUD launched in June 1991 by Linh Ngo, who was a computer science student at the University of Colorado at Denver. The MUD was named after the machine it ran on, copper.denver.Colorado.edu. Andrew Bradford, another UCD student and friend, later joined as a co-implementor. In December 1991 the Copper I source code was released, which was used in creating the popular Merc codebase, first released in December 1992. In early 1993 Copper II was released, followed by the release of Copper III more than a year later in 1994.
An area is an administrative unit of The Church of Jesus Christ of Latter-day Saints (LDS Church), which typically is composed of multiple stakes and missions. Areas are the primary church administrative unit between individual stakes and the church as a whole.
The areas as they now exist were formed in January 1984. Prior to that time, general authorities served as "area supervisors" and at times resided outside of Salt Lake City. In 1984, 13 initial areas were created; by 1992 there were 22, and by early 2007 there were 31. As of August 2012 there are 25 areas.
Until 2003, each area had a president and two counselors, all of whom were typically general authorities (area seventies were sometimes asked to be counselors). This three-man body was known as the area presidency. In that year, the church eliminated area presidencies for all areas located in the United States and Canada. Each of these areas were placed under the direct supervision of one of the seven members of the Presidency of the Seventy, thus freeing more general authorities from specific area assignments. Since these areas were previously administered by area presidencies located at church headquarters in Salt Lake City, the administrative change was not as drastic as it might seem.
In graph drawing, the area used by a drawing is a commonly used way of measuring its quality.
For a drawing style in which the vertices are placed on the integer lattice, the area of the drawing may be defined as the area of the smallest axis-aligned bounding box of the drawing: that is, it the product of the largest difference in x-coordinates of two vertices with the largest difference in y-coordinates. For other drawing styles, in which vertices are placed more freely, the drawing may be scaled so that the closest pair of vertices have distance one from each other, after which the area can again be defined as the area of a smallest bounding box of a drawing. Alternatively, the area can be defined as the area of the convex hull of the drawing, again after appropriate scaling.
For straight-line drawings of planar graphs with n vertices, the optimal worst-case bound on the area of a drawing is Θ(n2). The nested triangles graph requires this much area no matter how it is embedded, and several methods are known that can draw planar graphs with at most quadratic area.Binary trees, and trees of bounded degree more generally, have drawings with linear or near-linear area, depending on the drawing style. Every outerplanar graph has a straight-line outerplanar drawing with area subquadratic in its number of vertices, If bends or crossings are allowed, then outerplanar graphs have drawings with near-linear area. However, drawing series-parallel graphs requires an area larger than n by a superpolylogarithmic factor, even if edges can be drawn as polylines.
In architecture, an area (areaways in North America) is an excavated, subterranean space around the walls of a building, designed to admit light into a basement, often providing access to the house for tradesmen and deliveries and access to vaults beneath the pavement for storage of coal and ash.
The term is most commonly applied to urban houses of the Georgian period in the UK, where it was normal for the service rooms, such as the kitchen, scullery and laundry, to be in the basement. Areas were commonly enclosed for safety reasons by wrought iron or cast iron railings, which became one of the principal decorative features of the astylar terraced houses of this period. Areas are also found in the English and French country house, where basements were popular in the 18th century as a way of accommodating service functions while allowing all four faces of a symmetrical Classical building to relate directly to its landscape setting, as at Mereworth Castle in Kent or The Abbey, Skirwith in Cumberland. Basements, and consequently areas, decreased in popularity in the 19th century, as attitudes to servants changed, although they continued to be constructed as service accommodation in urban settings where land was at a premium until the early 20th century. A suburban residential application can be seen at the Gamble House in Pasadena, California, to light the laundry and service areas of the expansive basement.
