I checked findagrave.com but he's not listed.
I think looking for his obituary is a good idea but problematic because he's been gone for so long. Have you contacted the Loyalton Statation Library in Loyalton?
They may not have newspapers that old and you can contact the California State Library, library.ca.gov/calhist/genealogy.html which has the largest collection of newspapers in the state. However, they don't have the staff to look up obituaries but will send you a list of local researchers who will look one up for a fee.
There's a possibility that he's burial place might be on his death certificate (it's not alwayas listed in an obituary either). Again there might not be a death certificate either because of the fairly early date when he died. If you decide to go this route, contact the Sierra County Clerk-Recorder, sierracounty.ws/index.php?module=pagemaster&PAGE_user...
