Alberta is a very large and broad-stemmed lanceolate projectile point. These points have faint to prominent shoulders with the widest point at the shoulder. Alberta points show irregular to parallel transverse percussion flaking with pressure retouch. They share many of the same traits with Scottsbluff but differ in a number of respects. They are larger, the stem is longer, the base is slightly convex, and the tip is usually blunted. Length is 120 to 50 mm, width 30 to 15 mm, and thickness 8 to 5 mm. Wormington, H. M.
