Hauge (2013) claims to present a better model for the South Fork Fault System (SFFS) involving multiple movement events, yet he offers minimal evidence to support his fault timing and interpretation of non-catastrophic emplacement. In addition, he provides little data in terms of an emplacement mechanism for the SFFS. Likewise, his model (Beutner and Hauge, 2009) requires an unusual, concealed, linking fault between the Heart Mountain Fault System (HMFS) and SFFS that cuts downward approximately 1,500 m into underlying rocks.
