Jeff Gill, published by the Ohio History Connection Archaeology Blog, has written a two series post about the potential celestial alignments of the Alligator Mound at astronomical cross-quarter days.
"Along with those four points at the equinoxes and solstices, there’s a secondary four that has a fair amount of cross-cultural resonance. You hear a hint of it in “Midsummer’s Day” being June 20 or 21, which is astronomically what we call the “first” day of summer in modern America.
The midpoints of those first four, or Quarter days, are called Cross-quarter days."

"The protruding ridge where Alligator Mound is built at the end is the only place I can find in all of the Licking County region where you would have the “projection screens” at the right locations, enough vertical to the ENE & WSW to have these dancing shadow giants appear for a few moments just before sunset or right after sunrise.
Come May 3, I’ll be up atop this spot, now just before dawn, hoping to get some good film of the “Alligator Hill effect” against the side of Mount Parnassus, the isolated hill to the WSW. Maybe I’ll see you there!"
