Round Valley High School is a high school serving 445 students[3] in Eagar, Arizona, United States.

In 1962 that figure was down to 170 (which was up from 168 two weeks prior to the start of that school year).

[5] On June 11, 2010, a small plane crashed into the high school administration building, killing a family of four on board.

It might have been trying to land on the practice football field in high winds.

[6] The school owns the Round Valley Ensphere, a multi-use domed stadium that hosts football, basketball, and other sports events, plus non-school functions such as car shows.
