Description

Trowbridge and Shaw (1916) suggested that a northeast-trending syncline controlled the course of Smallpox Creek. Bradbury et al. (1956) named the Smallpox Creek Syncline and mapped its sinuous axis on the basis of outcrop study. Structural relief is a few tens of feet at the most. No significant mineralization has been discovered along the Smallpox Creek Syncline.
