Lower California (Baja California) is a narrow peninsula in western Mexico that is 1,247 kilometers long and 80 to 220 kilometers wide. It lies parallel to the Mexican west coast and merges with the Mexican mainland at its northern end.
To the west the Peninsula is bordered by the Pacific and to the east by the Gulf of California. In the cold, northern current coming from the depths to the Pacific coast, whales are observed migrating to and from their southernmost breeding sites. The Gulf, with its warmer water, is more comparable to the Mediterranean; the Colorado River flows into the Gulf to the north. (Source: Wikipedia)
