Native American Skies: Eclipse Legends



A couple of weeks ago, we observed a “Lunar Eclipse”.  Because this year is when the moon is in its minor “Lunar Standstill” (refer to article on Lunar Standstill at Chimney Rock), it was the shortest Lunar Eclipse for many years.  Because of the nature of the Moon’s and the Earth’s planes of orbit, an eclipse is an irregular event, that is, it appears to happen randomly.

Chaco Phenomenon (Yupkoyvi): A Hopi Story

The civilization that inhabited the canyon in central New Mexico known as “Chaco Canyon” was indeed a “phenomenon”.  Despite extensive archaeological study, there is little known of the society or the people that lived there.  It seems to defy fitting into a known political and/or ritual society.  As Lynne Sebastian, director of historic preservation programs at the SRI Foundation, puts it, “The extraordinary archaeological record of this society indicates both a strong political structure and an intense emphasis on ritual.”
 
So, why not look at the descendants of the people that lived in Chaco Canyon one thousand years ago?  Again from Sebastian, “these descendants have not only tenaciously survived, but have, to a remarkable extent, been able to preserve knowledge of their traditional lifeways.”  But, she sees their preserved knowledge as both a blessing and a curse, “. . . a blessing because it provides us with the potential for detailed, clearly applicable analogies for a wide variety of past behaviors.  It is a curse because the richness of the living cultures makes it too easy to grow myopic and not consider other cultural patterns from beyond this region.”

Dark Skies in Westcliffe/Silvercliff

For many centuries, dark skies filled with billions of twinkling stars was taken as a matter of fact.  Shepherds, nomads, farmers and travelers used the sky to guide them and teach them.  The movements and cycles of the heavens were well-known and closely observed by all.  But, as populations have grown, first candle light and now electric lights have slowly started to block out the night sky with their light domes.
Until recently, there were only eight places in the world “certified” as “Dark Sky Communities” by the International Dark-Skies Association headquartered in Tucson, Arizona.  They are:
  • Flagstaff, Arizona
  • Borregos Springs, California
  • Isle of Sark, Channel Islands
  • Homer Glen, Illinois
  • Isle of Coll, Scotland
  • Dripping Springs, Texas
  • Beverly Shores, Indiana
  • Sedona, Arizona

First American: New Discoveries

It seems that every year discoveries push back the date for the first Americans.  The January edition of the National Geographic magazine features an article on the discovery of a young teenaged girl who fell to her death into one of the many cenotes, or sink holes, in Central American Yucatan 12,000 to 13,000 years ago.  Although this date is roughly the date Clovis points were being manufactured in New Mexico and does not push back the date of first Americans,  of significance is its connection to the “Kennewick Man” discovered along the Columbia River in Washington.

Native American Skies: Lunar Standstill in Chaco Canyon

March 05, 2015
  
Earth-Moon declinations
In any given month, the rising moon swings between two extremes on the eastern horizon, similar to the oscillation of the rising sun during the year.  When the moon reaches its maximum northern or southern declination, it has a “standstill” similar to the sun at summer and winter solstices.  The standstills could be said to be the moon’s equivalence to the Solar Solstices.  [for details on lunar standstills, refer to Native American Skies: Lunar Standstills]

Native American Skies: Lunar Standstill at Chimney Rock

During the month, the moon rises at different points across the eastern horizon.  When it reaches the farthest point north it pauses, or rises in the same spot for a couple of days, and then reverses course.  This pause is called a “Lunar Standstill”.  The same thing happens two weeks later at its farthest point south.   You may have noticed that the sun does the same thing, but it takes the sun a year to move from its farthest point north (Summer Solstice) to its farthest point south (Winter Solstice) and back again.  At each solstice, the sun pauses before reversing course and this is called a Solar Standstill.

Native American Skies: Lunar Standstil

197px-Ecliptic_plane_3d_viewHave you noticed how fast the earth has been moving lately?  Probably not, but in fact the earth moves faster in the winter than in the summer.  The reason is because the earth moves around the sun in an elliptical orbit, not circular, so as the earth gets closer to the sun it speeds up and as it flies away from the sun it slows down.  In North America, the winter half of the year is approximately eight days shorter than the summer half.
