The autumnal equinox took place on September 22, marking the end of summer and the start of fall across the Northern Hemisphere. Autumn is the season of harvests, festivals, migrations, winter preparations, and of course, spectacular foliage. Across the north, people are beginning to feel a crisp chill in the evening air, leaves are reaching peak color, apples and pumpkins are being gathered, and animals are on the move. Collected here are some early images from this year's autumn -- more will come later as the season unfolds.
