Climate of the Great Plains

“The distinguishing climatic characteristic of the Great Plains environment from the ninety-eighth meridian to the Pacific slope is a deficiency in the most essential climatic element – water. Within this area there are humid spots due to local causes of elevation, but there is a deficiency in the average amount of rainfall for the entire region. This deficiency accounts for many of the peculiar ways of life in the rr West. It conditions plant life, animal life, and human life and institutions. In this deficiency is found the key to what may be called the Plains civilization. It is the feature that makes the whole aspect of life west of the ninety-eighth meridian such a contrast to life east of that line.”
