Hi Zachary, We'd need to know his last name to look this up.
Have you contacted the High School? Do a Google search to find the contact info. Many schools keep old copies of their yearbooks. When you do that Google search the annual might show up too.
Another idea is to contact the Nevada County Genealogical Society, rootsweb.ancestry.com/~cancgs/research_policy.htm . They might have the annual and do the lookup for a research fee. Successful Searching!
