The analysis here of 72 obsidian projectile points from Armijo Shelter (LA 9300) is dominated by the production of projectile ponts from obsidian sources along the Jemez Lineament, mainly sources from the Jemez Mountains (94.4%) north of the site, and one of the two Mount Taylor sources (Horace/La Jara Mesa) south of the project area (5.6%). Nearly 42% of the obsidian projectile points were produced from the Valles Rhyolite (Cerro del Medio) source in Valles Caldera in the Jemez Mountains.
