By the 1880s the Pinnacles, then known as the Palisades, were visited by picnickers from the surrounding communities who would explore the caves and camp. The first account of the Pinnacles region appeared in print in 1881, describing the Balconies area. Between 1889 and 1891, newspaper articles shifted from describing excursions to the "Palisades" to calling them the "Pinnacles". Interest in the area rose to the point that the "Hollister Free Lance" sent a reporter to the Pinnacles, followed two months later by a party of local officials. Investors came from San Francisco to consider placing a resort hotel there, but the speculation came to nothing. In 1894, a post office was established in Bear Valley. Schuyler Hain was the postmaster. Since at least one other Bear Valley was in California, the post office was named "Cook" after Mrs. Hain's maiden name. In 1924, the post office was renamed "Pinnacles".
