By coincidence I ran across a contemporary reference tonight while searching for something else. Under an entry dated 6 January 1847, the Mormon Church History blog summarizes a letter as follows:
"Letter to Elders Hyde, Pratt, and Taylor-- This is a letter of Brigham Young and members of the Council of the Twelve Apostles who were at the Camp of Israel, Omaha Nation, Winter Quarters, near Council Bluffs to three members of the Council who were on a special apostolic mission to England. The letter is an excellent summary of conditions as they then existed with the Saints in their "Winter Quarters" preparatory to the trek west the following summer."

This might not be the best way to describe the location for modern genealogy but it's certainly an insight into a contemporary usage.
