Hi Dawn, I couldn't find an on-line index of Valley View Cemetery. You must have some family knowledge that indicates he was buried there because he died in Harney, Harney Co.
If you're sure, he was buried in Malheur Co. there are a couple of cemetery volunteers at Random Acts Genealogical Kindness. Go to raogk.org Choose Oregon Click on L thru M Scroll down to Malheur Co but only ask if they have the listing for Valley View. It's not really fair to ask them to traips through a cemetery when we're not sure he was buried there.
Do you have a copy of his obituary? Some times the cemetery is listed in the obituary or on a person's death certificate.
There is a public record volunteer in Harney Co. at Random Acts Genealogical Kindness. Go to raogk.org Choose Oregon Choose E thru K Scroll down to Harney Co. and choose Lois.
You can contact the Harney Public Library, harneycountylibrary.org/western-hi... for a copy of his obituary. Successful Searching!
