first recorded 20th c. disputed origin

The term entered the lexicon by the 1910s, originally serving as a playful designation for geologists working within the nascent oil industry. It belonged to a specific professional jargon that included labels such as "sand smeller," "oil witch," "wrinkle chaser," and "pebble pup." The name suggested the geologist possessed a canine ability to sniff out items of value buried amongst the stones.

While early instances appear in Citations from the 1910s, the term was perhaps popularised by a story published in Cosmopolitan in 1921 titled The Rockhound. The narrative utility of the word likely assisted its transition from the specialised vocabulary of the oil fields into more general usage.
