Early photographs of the Union Pacific trains and the "Pillars of Hercules" often label them as the "Needles".
Early newspaper articles used the name "Needle Rocks".
"... it will be possible for automobiles and other vehicles when the highway [Historic Columbia River Highway] is completed to spin down the slopes of a precipice from Chanticleer to the Columbia River, a drop of 900 feet; proceed eastward at the base of Rooster Rock, through the fields and farms about the village of Latourelle; past the Needle Rocks; along the base of Gordon, Latourelle, Multnomah, Bridal Veil and Horsetail Falls; through the grandeur of Oneonta Gorge; over the plateaus this side of Hood River; along the picturesque Tanner and Eagle creeks; over the old Dalles military road, and lastly around the now treacherous precipices of Shell Rock. ..." ["Sunday Oregonian", August 10, 1913]
