Pleistocene Autumn September is another one of those months that can go either way. During a Pleistocene Autumn, heavy September and October rains and cool temperatures bring forth billions of wildflowers which carpet the countryside.
Ground fogs lie along the bottomlands at dawn, and dew drips off every cactus and creosote bush.
Secret springs, which run for only a few hours after heavy rains, appear in unexpected places. A woolly mammoth appearing from behind the next mesquite clump would not be entirely unexpected. A Pleistocene Autumn gives a taste of what our climate used to be, and it might be like again, for all we know. Whether or not we will have a Pleistocene Autumn this fall is anybody's guess. With all the heavy rains we've been having for the past 10 years or so, one might wonder if we're undergoing a change in climate, and if so, what kind of changes can we expect in our plant and animal life.
