Arrowhead Post Office opened 1 July 1896, so-named by the CPR, as it is at the head of Arrow Lakes; closed 28 September 1968.
Note that BC name card identifies "Halls Landing Post Office" as an old name for Arrowhead. Halls Landing is a separate location about 3 miles northwest up the the Columbia River; it is likely that mail was delivered via steamship to Halls Landing until a steamer landing and post office were established at Arrowhead.

"For many moons the Indians camped at (this) splendid site and were happy. The fishing was good and so was the hunting, and many tribes came during the summer. They were happy and peaceful but enemy tribes coveted the camp ground and raided this camp of many totems. A great battle ensued and many warriors were killed and many arrows spent. For many moons following the great battle no one came to this camp-ground, and when - years afterwards - the white man came and dug cellars for his teepees of lumber, he found many arrow-heads and so called the place Arrowhead. The name might also follow from the fact that being the Arrow Lakes, the head of these lakes would naturally be called Arrowhead. Another story is that if one climbs the high mountain at the back of town, the arm of the lake resembles the head of an arrow." (The Slocan Enterprise, 5 February 1930).
