Toltec Mounds Archeological State Park, Scott | 7:23 P.M.

Though there’ve been a smattering of after-dark activities filling local calendars of late, this is one sure to define the season: On Sept. 21, Toltec Mounds Archeological State Park will keep the gates open well past 5 p.m. to fete the fall equinox, hosting a guided tour at 6 p.m. of the nearly 1,400-year-old settlement that will culminate with the sun dropping over mound A at precisely 7:08 p.m. For those unfamiliar with the property—or the park’s status as a National Historic Landmark—it’s worth noting that not only is the less-than-super-creatively monikered mound A the tallest such structure in Arkansas, it’s also one of the longest enduring, dating back to the Plum Bayou culture (ca. 650 A.D. to 1050 A.D.).
