English: A 1/3rd scale replica of Stonehenge at the MacKay Jaycees Family Park in Grand Rapids, Michigan. The monument built out of Michigan's most abundant natural raw material is appropriately named Snowhenge. Standing 6.5 feet tall and 30 feet in diameter and consisting of nearly 1000 cubic feet of packed snow, Snowhenge's 12 pillars and 12 lintels are perfectly aligned astronomical markers. Looking directly through the hole in the center of pillar 3 soon after sunset on Winter Solstice extraordinarily reveals an almost equilateral triangle formed by the visible planets Saturn (left), Mars (top), and Venus (right). A curious carving on pillar 4 shows four stars inside a trapezium which matches the Trapezium Star Cluster in the Orion Nebula. The imaginary end point of a line dissecting the trapezium matches the coordinates of the star Sirius, the brightest star in the Milky Way. An obelisk inside the snow circle marks the passage of the sun as its shadow moves in a figure eight on the ground below. Stone plaques strategically placed on the ground display the constellations of the zodiac. Outside the circle, three pairs of standing snowmen show where the sun rises and sets for each of the solstices and equinoxes. Every key point also has a rock plaque denoting its seasonal significance engraved with a simple phrase like "Midsummer Solstice Sunrise". Others describe local area seasonal events such as "Blandford Sugarbush", "Grand Rapids Festival of the Arts", "28th Street Metro Cruise" and "Celebration on the Grand". The 12 lintels, supported by 144 rods of ice rebar, also contain markings that coincide with the orbital patterns of Earth and Venus which are designed to forecast solar eclipses, the appearance of comets, and the end of the world on December 23rd of 2012, exactly matching the Mayan calendar prediction. What's most truly remarkable, pillar 1 is precisely parallel with 28th Street! Curiously, the phenomenon known as global warming which has created isolated heat zones around the globe inversely causes cold spots on the opposite side of the globe. Numerous consecutive years of record heat spikes in Perth, Australia are directly responsible for the extraordinary cold snaps at MacKay Jaycees Family Park which will amazingly keep Snowhenge frozen all year round.
