Driving on Map Rock Road alongside the Snake River will bring you close to panel of ancient rock carvings called petroglyphs. The road was named after the most well-known petroglyph in the collection called “Map Rock.”

Historian and Boise State University Professor Todd Shallat describes this unique rock in his book “Snake: The Plain and Its People:”

“While probably not a 'map' in the modern sense of the word, this petroglyph at Wees Bar in southern Idaho might have been carved to plot or chart constellation changes or herd migrations,” Shallat writes.

Seeing Map Rock up close requires crossing the Swan Falls dam and following a trail to an area known as Wees Bar. There you will find a boulder field with over 90 petroglyphs including Map Rock.

Shoshone-Bannock tribe members are thought to have made these etchings prior to contact with European settlers.

Map Rock is listed on the National Register of Historic Places. The rock became part of a park owned by Canyon County in 2012.
