Apparently, during the time that the Nephite armies were gathering to the land of Joshua, Mormon mentions that "a complete revolution" (Mormon 2:8) had been going on throughout the land of Zarahemla. According to John Sorenson, archaeological evidence in Chiapas, Mexico, a proposed site for the land of Zarahemla, seems to reflect this "revolution." According to a report on the site of Mirador (proposed area of Angola) by archaeologist Agrinier, the Jiquipilas phase (A.D. 250 to 350) "was ended by an intense fire that totally destroyed" the structure of the largest sacred building at Mirador. "It seems that the temple had been thoroughly cleaned of its contents prior to its burning." This suggests either a scorched earth policy on the part of retreating inhabitants or looting by the invader, or both." Tombs at the site were sacked at the same time. After the destruction of the temple, a period of temporary abandonment followed, perhaps as little as a single year. . . . When Mirador was settled anew, it was by a new people. The buildings suggest "shoddier construction" by "a transitory elite . . . more concerned with quickly-secured grandeur than with long-range durability." That sounds like what we could expect from the Lamanite invaders who followed on the heels of Mormon's retreating people. . . . In addition, it turns out that the invaders who looted and burned there, arriving on the heels of the populace abandoning the site, displayed a mixture of Guatemalan and Teotihuacan traditions.
