Map Rock


In November of 2012, Canyon County acquired Map Rock, a famous Idaho petroglyph, and 34 acres of surrounding property for the creation of another park.  With the acceptance of Map Rock, Canyon County takes on the responsibility of its protection and accessibility to our citizens and visitors. Canyon County Parks and Recreation is planning an educational environment at Map Rock and an agenda that will assure its protection, preservation of context and accessibility for students and the life-long learners. We look forward to working with the Idaho State Historic Preservation Office and consulting with the Shoshone-Bannock Tribe of Fort Hall, Idaho, to create a conservation program for this site.

Map Rock is the most well-known petroglyph panel in Idaho. It is a large, basaltic spall on the Snake River that supports a great variety of petroglyphic elements on its south, east and top faces. It is commonly believed that the panel was created by Shoshone-Bannock people prior to Euro-American contact. The Shoshone-Bannock of Fort Hall, believe that Map Rock is a map of the Snake River region. It is a very important spiritual site for these people.
