Here’s a San Joaquin County trivia question: What is the highest point in the county?
It’s the 3,621-foot Mount Boardman located southwest of Manteca in the Diablo Range.

 It is on the Alameda-San Joaquin county line near where those two counties meet Santa Clara and Stanislaus counties.

You can see Mt. Diablo looking slightly to the northwest as you head west on the 120 Bypass past Airport Way.

Mt. Boardman is the second highest peak as you look to the southwest from most points in Manteca. 

The highest peak— by 8 feet — in the area as you look to the southwest is just to the north of Mt. Boardman at 3,629 feet and is within Alameda County.

Mount Boardman, was named after W.F. Boardman who served from 1865 to 1869 as the Alameda County surveyor.

Mount Boardman North — not originally named — ended up being slightly higher than the surveyor’s namesake.
Del Puerto Canyon  Road out of Patterson via Interstate 5 brings you closest to the peak form the east. Mount Boardman North is 220 feet shorter than Mt. Diablo — the third highest peak in the San Francisco Bay Area at 3,849 feet.

It should be noted that Mt. Boardman is private property and is not accessible to the public
