Initial Point

Ada County · Idaho

The point was fixed on April 19, 1867, by Peter Bell, Cartee's brother-in-law, from observations of the stars, on top of a small volcanic butte about eight miles south of Kuna. Every township and section across nearly 54 million acres of Idaho is counted from it. What marks it is modest: a brass cap about the size of a jar lid on the summit, where a viewing platform went up in 1962. The cap has been spray-painted, shot at and stolen. The Bureau of Land Management held a celebration for the point's history in Boise in May 2026.

What the plaque says

Initial Point All Idaho land surveys refer to a beginning point --"Initial Point"-- 16 miles directly south of here. When he began surveying Idaho in 1867, Lafayette Cartee, first surveyor general of Idaho Territory, established the initial point on a volcanic hill visible for many miles. Everywhere in Idaho, surveyors depend upon this essential point in establishing land boundaries. The city of Meridian is named for the Boise Meridian--the surveyors' north-south line which runs through Initial Point. 193 Text prepared by the Idaho Historical Society Marker made & installed by Idaho Transportation Department
