* Intermountain Indian School Alumni Association: This is your best bet. Check their website (if they have one) or contact them directly. They may have alumni directories or be able to assist you in connecting with graduates from that year.
* Social Media: Search Facebook, LinkedIn, and other platforms for groups associated with Intermountain Indian School or for individuals who list the school in their education history. Use variations of the school's name in your search.
* Classmate Finders: Websites like Classmates.com or Reunion.com sometimes have directories that allow searching by school and graduation year. However, success is not guaranteed, as participation is voluntary.
* Online Genealogy Sites: Sites like Ancestry.com or MyHeritage.com might have yearbooks or other records that list graduates. However, you'll need to be a subscriber to access most of their content.
* Tribal Records: Depending on the tribe(s) the graduates belonged to, the tribal archives or offices might possess some alumni information. This requires knowing the specific tribes represented at the school.
Remember to be respectful of people's privacy in your search. If you find someone, approach them politely and explain why you're looking for them.
