Celebrations of solstices and equinoxes are documented in almost every culture worldwide. These quite varied events have become regional staples, especially in the northern hemisphere, where the date around June 20-21 each year represents the longest day and most sunlight before the sun begins its semiannual trek back to the south.
In Sweden one may encounter a midsummer celebration, with revelers dancing around the maypole, adorned in festive attire, while neighboring Norway celebrates with massive bonfires. As Christianity spread across Europe, many of these ancient rituals merged with the traditional birthday of Saint John the Baptist on June 24, for deeply religious symbolism. In Barcelona, communities commemorate the holy day with feasts and bonfires lit from the Canigó Flame, burning continuously since 1955. Comparatively, Alaskans celebrate the long summer sun in many ways, including a midnight baseball game in Fairbanks — with no artificial lighting — indigenous games and a “polar-bear swim” in Nome.
Possibly the best known solstice events occur at ancient megaliths. The 5,000 year old a ar Qim site in Malta was built so that the solstice aligned a hole in a wall to create a crescent-shaped light that morphs into an ellipse and the disappears as if sinking into the ground. The most famous of these is Stonehenge, where thousands will gather this year to witness the sun rise behind the Heelstone.
That so many cultures, separated by thousands of miles and thousands of years, all did a pretty good job of coordinating with the modern calendar could lead one to credit ancientalien conspiracy theories. Archaeoastronomers, however, know better. From the solar alignment of the Temple of Kukulcan at Chichen Itza to the layout of the entire Angkor Wat complex in Cambodia, humans have observed the sun, measured its movements, and calculated its future positions for thousands of years.
Venturing across the central highlands of northern Arizona one can also find such monuments left in the strata of history. The indigenous inhabitants of these lands as well as passing travelers left their marks on the landscape, as evidenced by ruins and petroglyphs found throughout the region. One such location is Solstice Mesa, nestled in a protected park in Prescott Lakes at the end of Tawny Drive. Rock art throughout this short hike tells the story of thousands of years of regional habitation, as well as the record of the changing of the seasons. This monolithic ephemeris aligns with a crag in Granite Mountain at the Summer Solstice, and again with Thumb Butte at the Winter Solstice. Such an alignment cannot be mere coincidence, and silently speaks to the advanced astronomical understanding of the early Yavapai and other peoples who have called this land home.
