Toos fertile plain, located between two mountain ranges Hezarmasjed and Binalood, has attracted different ethnic groups through ages due to environmental conditions, and has provided a proper ground for human inhabitation and continuation of life since oldest times.
Discovery of handmade tools dated to Lower Paleolithic Age in the middle of the plain and banks of Kashaf River (Kashaf Rud), existence of ancient caves and density and variety of settlements at prehistoric, historic, Islamic and modern times are valuable evidence in this field.
Around these settlements numerous rocky graphs have remained that could be considered a part of artifacts and relics of inhabitants in these settlements. These rocky patterns are scatted at the margins of Toos plain, presenting various subjects like hunting scenes, primitive tools, lattice patterns of naked human body, bison, symbolic designs and signs, human images taking part in battles, hunting and rituals, and goats along with symbolic signs such as circle of sun.
Based on the existing evidence and documents, these graphs could be attributed to prehistoric and historic periods whose creation has continued in the following periods.
