Loyd Doty notes:
GUAJADEMÍ (Stemmed Bifurcate) – are small points with corner notches and concave bases. They were defined by Eric Ritter after the Guajademi community west of Bahía Concepción in central Baja. Hyland lumped this type within the Elko series; however, the small size of Guajademí points would seem to make that assignment questionable. In some respects, the Guajademí points seem similar to Rose Spring points, although the latter more commonly have straight or convex bases. Ritter considered the Guajademí Split-stem type as one of the hallmarks of the Transitional period between 1,5K and 1,8K years ago.
