Used in conjunction with the CHAPS Program’s “Lower Rio Grande Valley Projectile Point Types” poster, this educational tool will interest and intrigue educators, students, and natural history tourists alike. Use of this app will allow the viewer to see projectile point artifacts in 3D as they come off the page. Each historic and prehistoric time period includes a description of the epoch itself, a short film illustrating the era, and detailed information identifying each individual projectile point artifact on the poster. Just download the app and point it at the poster. All seven time periods will appear, and you can navigate through each one by selecting the period name.
