The Gabilan Range trends in a northwest–southeast direction along the Monterey County and San Benito County line. It is bordered on the northeast by the
San Andreas Fault, the
San Benito River and
State Route 25 which separate it from the
Diablo Range to the east; and on the west by the
Salinas Valley, the
Salinas River and
U.S. Route 101 which separate it from the
Santa Lucia Range nearer the Pacific Coast. The northern limit of the Gabilan Range lies just south of
Pinecate Peak and
San Juan Bautista, California. According to the USGS GNIS, GPS coordinates for the southern border of the Gabilan Range follow Chalone Creek which enters the Salinas River east of
Greenfield, California. Chalone Creek is the principal drainage of
Pinnacles National Park. Mount Johnson (California), at in elevation, is the range's highest point. There are several other peaks also over in the range. ==History==
