Millions of years ago, a river cut a 600-foot notch into the Red Hills of Iron County.
That cut, now known as the Parowan Gap, is believed to have the most concentrated collections of petroglyphs in the West, with over 90 panels featuring some 1,500 figures, dating back to 500 A.D. when the Fremont Indians roamed the region.
Located 11 miles west of the town of Parowan, the Navajo sandstone gap is covered in a patchwork gallery of American Indi-an rock carvings. Images of human figures, spirals, snakes, bear claws, lizards and geometric designs and the site holds sacred meaning for the Hopi and Paiute nations. The most interesting feature of the site is a large and deeply in-scribed petroglyph, the Zipper Glyph, aptly named because it resembles a giant zipper.
The glyph has been interpreted a number of ways, including a composite map of space and a numerical calendar, a planting guide, a map of travels and a story about a great leader. Although the writings have different meanings to Native Americans and have been theorized by astronomers and archaeologists, the true meaning of the petroglyphs remains a mystery. Interpretative events at the gap are offered in conjunction with the summer and winter solstices, spring and fall equinoxes, and lunar events.

(Leah Hogsten | The Salt Lake Tribune) The Zipper Glyph, March 20, 2021 during the spring equinox, or one of the two times during the year the sun illuminates the northern and southern hemispheres equally. The Zipper Glyph is the largest petroglyph at the Parowan Gap and has been interpreted in different ways. The Paiute Indian Tribe of Utah believes the glyph depicts the story of a migration where many people experienced famine, drought, water crossings, cold, ice and hot sun and of a great Leader. The petroglyph also has been researched by an astronomer and archaeologist who believe the glyph is based on astronomical events, depicting the movement of the sun, moon and stars as a means to track and chart seasonal changes including the summer and winter solstices and the equinoxes among native people. Those theories are still under review by scientific and American Indian communities.

"It's fascinating, the information that's here."

Researchers believe that the petroglyphs written into the Navajo sandstone at Parowan Gap were pecked and scratched by Native Americans who were living and farming in the Parowan Valley around 500 A.D., a time period archaeologists call the Fremont period. The Fremont Indians are closely related to the modern-day Hopi and Piute tribes and the Parowan Gap is a sacred site for both tribes.

"We call him the Overseer," said Dalton. "In November, the sun rolls into his mouth and he swallows it and then he spits the sun out of his mouth in February."
