Its officially fall in the Pacific Northwest. After a long spring where the average temperature slowly meanders up, and a blissful long summer where the mountains showcase all their splendor, the mercury drops in a matter of a few weeks in the mountains as the weather becomes wetter thanks to the storms from the Pacific. The vegetation responds to the changes in weather rather dramatically, as short brush in the high-alpine terrain turn to a scarlet red, while the larches in the drier reaches of the PNW switch to gold. And before long, they are replaced by a coat of white as winter sets in the mountains. All within a span of 4-6 weeks.
Naturally, it is one of the best times to be out there to capture this dramatic change in colors. Here are a few examples from the North Cascades range.
