The Dot "T" Johnson and Cathedral Rapids faults represent the eastern part of the Northern Foothills fold and thrust belt, and are geomorphically well expressed by triangular facets, anticlinal warps, and scarps in Quaternary deposits between Granite Mountain and Tok River. Previous paleoseismic trenching indicates that these faults have both generated at least one and possibly multiple Holocene earthquakes. We created various LiDAR-derived base maps along the Dot "T" Johnson fault to assess the relative utility of each product in assessing the location of tectonic features. Our results indicate that the most robust interpretations require combined observations from multiple products including hillshade, slope,...
