I have the 2009 Church Almanac.
In the Fifth Quorum of the Seventy, there are these six names for the Idaho Area:
Robert E. Chambers, Kim B. Clark, Ronald J. Hammond, K. Brett Nattress, Brent H. Nielson, Gary W. Walker
So these six are under the First Quorum of the Seventy, who are under the Presidency of the Seventy, who are under the Quorum of the Twelve Apostles, who are under the First Presidency? So these are the six men who provide the head oversight over the 400,000 LDS members in Southern Idaho?
