Talk:Chino Hills

Is Chino Hills an actual mountain range?
There is the city of Chino Hills, California and there is Chino Hills State Park, but I cannot find a citation referring to the geological formation as Chino Hills. Is it possibly part of the Santa Ana Mountains instead? I am just wondering if the actual hills are officially called something besides Chino Hills? A reference to a scientific journal would be helpful. Thanks, Alanraywiki (talk) 18:50, 12 August 2008 (UTC)
