Hero Eugene Rensch reports that the explorer Captain George Vancouver wrote the most about the Pinnacles in 1794, and that they were relatively undocumented from that time until Harold W. Fairbanks wrote about them in the 1890s. After 1900, local newspapers and tourism booklets mentioned the Pinnacles “as unusual wonders of nature.” It was David Starr Jordan, the President of Stanford University, taking an interest in the Pinnacles which spurred President Theodore Roosevelt to create Pinnacles National Monument.
