Over the last 135 years, Memorial Day weekend visitors to Mountview Cemetery have sometimes needed a little help finding the grave of a loved one. But from 10 a.m. through 2 p.m. Saturday through Monday, a group of volunteers and park staff, equipped with thick lists of graves and walkie-talkies, will be ready to help. The Billings Gazette reports that thousands of names are already in the database, but not everybody who’s buried at Mountview has their data entered. A Memorial Day service will be held at 10 a.m. Monday.
