A petroglyph is a rock carving, especially a prehistoric one. We checked out these Petroglyphs that were located at Celebration Park in Melba, Idaho which isn’t more than an hour outside of Boise.

Entry to the park is $2 per vehicle. The Visitor Center, open 10:00AM to 2:00PM from April to October, provides restrooms, knowledgeable park staff, and maps for the Petroglyph Trail.

The Petroglyph Trail winds through glacial boulders, called “melon boulders.” The melon boulders are covered in a dark sheen. That sheen, when removed by carving, reveals the lighter rock underneath. And thus, a petroglyph is born. Many of Celebration Park’s petroglyphs are between 10,000 and 12,000 years old, with some as new as 400 years old.
