Located in Pioneer Park in Ephraim, Utah, this mill stone is on display with a sign that says:

There used to be a burr mill called the Climax Mill in southeast Ephraim across the creek from Guards Knoll. It was called a burr mill because of the Burr Stones which were used to grind flour. These stones were a very special, hard type of stone found only in Buhr, France.
These stones were made in many sizes usually ranging from 12 to 48 inches. This mill stone (a.k.a. burr stone) came from the yard of the Hermansen home that was located on the corner of 100 North and 100 East in Ephraim. That is where the Ephraim College Student Stake Center now stands.
