This is near Supai Summit west of Williams at milepost 382. From here the line drops more than 1,800 feet to Ash Fork. The original mainline through Johnson's Canyon was on a three percent grade. In 1911, the Santa Fe added double track between Williams and Ash Fork. The new line for eastbound trains was on a two percent grade that was three miles longer. This line split from the original mainline at Welch and rejoined at Supai.

Later that afternoon local 3151 the train to Phoenix comes around the same curve. The road in the foreground is the old US66. Disk 73
