If you visit the Holly Group on certain days of the year, you can see an example of how ancestral Puebloans possibly determined the solstice and equinox by tracking the sun’s position. In late May and June, vicious gnats, known locally at Pinyon gnats, are common. They descend like a Biblical plague of locusts. Bug repellent will help but we haven’t found anything that will actually stop them. If you plan to visit Hovenweep for the Summer Solstice, you’ll probably be OK because they are not usually active at sunrise. But, shortly thereafter, they will be out in force. Our advice: don’t camp here during gnat season.

Solstice Markers and Puebloan Skies: Observational astronomy has deep and abiding roots in the Puebloan world of the northern Southwest. Archaeological evidence suggests that the ancestral Pueblo Indians (Anasazi) marked astronomical events, perhaps as guides or records of their agricultural and ceremonial calendars. Rock art and architecture were carefully placed so that beams of sunlight would interact with rock images on important seasonal days such as equinoxes and solstices, marking the days with remarkable precision.

At summer solstice, mystic pilgrims now flock to one of the park’s ceremonial kivas, where sunlight beams through an opening and illuminates a niche on the opposing wall. One year, a ranger placed a cardboard cutout of Elvis in the ruin. At dawn, the image of the King greeted the chanting revelers. I wish I’d been camping there then to have seen it.

At Hole-in-the-Rock, the Hohokam marked the occurrence of the summer solstice by grinding a bedrock metate slick at the location where the ray of light falls during that day around noontime.

The Shaw Butte site petroglyphs relate to the astronomical observations at the site. The centerstone has been aligned with winter solstice sunrise and summer solstice sunset. The centerstone acts as an instrument to mark the solstices. The flat face of the boulder is in shade as solar noon approaches the time of summer solstice. A notch in the top of the stone allows a tiny shaft of light to touch the middle of one of the circle/dots. As the sun continues to approach zenith, the spot of light grows until the majority of the face is awash in light.

Frank Pinkley noticed that there was a system of holes in the east wall of the Great House through which the rising sun aligned each year on the mornings of March 7 and October 7. By 1918, without any study or investigation, he explained to visitors that these holes were used twice each year as a solar calendar to date ceremonies. In 1920 Pinkley broadened his astronomical interpretation after he discovered holes in the Great House’s north wall. He invented an elaborate initiation ceremony story, which involved “calling down the stars,” to explain these holes.
