Graduating Class anywhere from 1919-1921

This a the graduating class from either Pleasant Hill New Mexico or Clovis, New Mexico. I am not sure and would like to find out. I can identify only 2 people from the back row. They are: 2nd from left Doc Barnes (I believe his first name is really Richard) and the last person standing on the right is my great aunt Una Fay Clark (Baumgartner). Fay was Deputy County Clerk, then County Clerk, in Clovis for a total of 39 years.
