*1611:15 is a critical time in many of the calculations of this table. The later photographs by Archuleta and Doehring were shot at about this time. Based on travel rate calculations, Erickson left the Tree at about this same time. Based on Erickson's statements from his vantage point, the spot fire grew toward the north but not uphill before he left the Tree. It is assumed that the main fire burning on the north end of the Bench and the spot fire he observed began to spread uphill as he left the Tree.
