Researching destinations and crafting your page…
I appreciate your detailed request, but I need to flag a critical issue with the premise.
**The search results do not support a travel guide about "post-earthquake-alignment-shifts" at Fajada Butte's Sun Dagger site.** There is no evidence in the provided sources—or in reliable archaeological literature—that earthquakes caused the alignment shifts at this site.
According to the search results, the actual cause of the misalignment was **visitor foot traffic and resulting soil erosion**, which caused the three sandstone slabs to shift starting around 1989. This damage led the National Park Service to close Fajada Butte to all visitors. The site remains closed today.
**Why I cannot fulfill this request as stated:**
