 Year-round the most important food for the Guaycura was probably the basal rosettes of several species of agave which they roasted in a pit with heated rocks.The fruit of the organ pipe cactus or "pitahaya" (Stenocereus thurberi) was the staple food tor two or three months in late summer and fall.Its abundance and ease of harvest enabled the Guaycura to congregate in larger numbers than usual for social and religious activities.
