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. Alexander Kempt paddles past the Baroque Palace in a hollowed out pumpkin as he takes part in the German Pumpkin Boat Championship on September 16, 2012 in Ludwigsburg, Germany. The 40 participants of the competition may either use one of the pumpkin boats furnished by the organizers or are allowed to use a self-made boat constructed of a pumpkin weighing 200 kilograms or more. Leaves along the Androscoggin River are at peak color in Berlin, New Hampshire, on September 28, 2012.
