Unreferenced date December 2009 Keystone Heritage Park is an archeological site , an archaic wetlands and a botanical garden. The Convert 52 acre m2 sing on park in El Paso s Upper Valley is a City owned park managed by a volunteer Board of Directors who are charged with preserving and developing the Park. The archeological site was first discovered in the late 1970s by the Corps of Engineers during the construction of flood control dams. Runoff from a thunderstorm washed away the bank of a shallow arroyo revealing a cut away of an ancient pitch house. Preliminary research revealed the hut was part of a larger village. Carbon dating indicated the site was 4000 years old. According to National Geographic Magazine, it may be one of the largest and oldest villages of its kind in the United States. Keystone Wetlands is home to many species of birds and is a stop on a migratory route for even more. Over 180 species of birds have been spotted there, including five species considered rare by the Audubon Society. These archaic wetlands, protected by Federal Law, depict the wetlands that once lined the Rio Grande. The Botanical Garden at Keystone is a project adopted by the Junior League of El Paso in the year 2000. In 2003, the Rotary Club of El Paso committed to building Phase Two of the garden. The Garden encompasses features such as a Xeric demonstration garden, a children s garden, an amphitheater, a moonlight garden, an ethno botanical garden and more. Keystone Heritage Park is currently an IRS approved 501 c 3 organization with a 15 member board of directors composed of community leaders and volunteers.

That route is now served by the Pennsylvanian Amtrak Pennsylvanian . Prior to Amtrak the route was known as the Duquesne , named after Fort Duquesne in Pittsburgh, and was operated by the Pennsylvania Railroad . Today Keystone trains offer frequent service between Penn Station and Harrisburg. History The Duquesne had a long history, finally becoming a daily New York Pittsburgh train October 25, 1959, numbered 16 eastbound and 25 westbound. With the start of Amtrak operations on May 1, 1971 the Duquesne was kept, and was renamed the Keystone and renumbered 42 westbound and 43 eastbound with the first brand new Amtrak timetable on November 14, 1971. Trains 42 and 43 are now the Pennsylvanian Amtrak Pennsylvanian .

how to date February 2012 Image Vertical keystone.jpg thumb 300px right Illustration of the keystone effect The keystone effect , also known as the tombstone effect , is caused by attempting to project an image onto a surface at an angle, as with a projector not quite centered onto the screen it is projecting on. It is a distortion of the image dimensions, making it look like a trapezoid , the shape of an architectural keystone architecture keystone hence the name of the feature. In the typical case of a projector sitting on a table, and looking upwards to the screen, the image is larger at the top than on the bottom. Some areas of the screen may not be focused correctly as the projector lens optics lens is focused at the average distance only. Theory The distortion suffered by the image depends on the angle of the projector to the screen, and the beam angle. The distortion on a two dimensional model, and for small focus angles is best approximated by center math frac cos varepsilon alpha 2 cos varepsilon alpha 2 math center where math epsilon math is the angle between the screen axis and the central ray from the projector, and math alpha math is the width of the focus. From the formula, it is clear that there will be no distortion when math epsilon math is zero, or perpendicular ...
