The image here is from the commonly visited Yaki Point, a part of the Kaibab Trail. While the colors displayed seem more modest and limited than in previous photos, this can be a result of the time of day the picture was taken.
The description states:
GRAND CANYON NATIONAL PARK, ARIZONA
Looking East from Yaki Point
In the late afternoon, the majestic architecture of the Grand Canyon becomes more pronounced with the lengthening of the shadows.
–In different lighting conditions, there is extensive red coloration as well as the yellow and brown shown here. This card likely dates from the 1960s.
