Rick McLure recognized last week’s photo of petroglyphs (shown above) on the lower John Day River.

“The photo depicts two petroglyphs, one of a mountain sheep, the other a four-pointed star,” he noted.

A searchable database of immigrants’ names, scratched or painted on rocks along the Oregon Trail, arrived at Columbia Gorge Discovery Center and Museum on Aug. 28. The collection is donated by photographer Jim Henderson, who spent years along the Trail photographing rocks with cross-pollarized light to reveal many hidden names.
