The California culture region stretches from southern Oregon through Baja California. Ocean storms bring winter rains to this region. But summers are hot and dry, particularly inland.
1.9 Native Americans of the Southwest
To the east of California lies the Great Basin, a low area between the Sierra Nevada and the Rocky Mountains. The mountains on either sides of the region block rain, making this land mostly desert.
1.10 Native Americans of the Great Plains
North of the Great Basin lies the Plateau culture region. This region is bounded by the Cascade Range to the west, the Rockies to the east, and the Fraser River, in present-day Canada, to the north.
1.11 Native Americans of the Eastern Woodlands
The Southwest culture region includes present-day Arizona, New Mexico, southern Utah and Colorado, and portions of Texas, Oklahoma, and California. This region has many environments-canyons, mountains, deserts, and flat-topped mesas.
In the Great Basin, it was mostly desert everywhere. Because of this, the only inhabitants there were small animals like rabbits and lizards, and there were plants that grew on a little water supply. The Great Basin was located between the Sierra Nevada and the Rocky Mountains, so the mountains would block rain from getting to the basin.
The Eastern Woodlands culture region reaches from the Mississippi River eastward to the Atlantic Ocean, and from Canada to North Carolina. Here, winter snows and summer rains produce endless forest, lakes, and streams.
