I was asked in the comments recently if I had time to photograph autumn colours. Last week, I was in the Alberta and British Columbia Rockies hoping to do just that, but because of the hot and dry autumn, colours were overall poor. In fact, many trees had crisped brown leaves instead of any sort of colouration. This photograph is from my 2011 trip. It's a good example of how photographs can omit--the split stream flows through a triangular piece of land bordered by roads (which you can see via the Google Map).
The yellow-leaved trees are young black cottonwood or Populus trichocarpa while I believe the conifers in the foreground are Engelmann spruce, Picea engelmannii. The other possibilities for the conifers are Picea glauca (white spruce) or the hybrid between the two species.
