Collection Overview: The contribution comprises high-resolution topography and orthomosaics of part of the Lost River fault zone (LFRZ), Idaho, USA. The data set covers the northern ~16 km of the surface-rupture that occurred on the LRFZ in the Mw 6.9 1983 Borah Peak Earthquake. Point clouds and digital surface models (DSMs), were generated from low-altitude aerial photographs using Structure-from-Motion and multi-view stereo processing (SfM).  The LRFZ is a major, range-bounding, west-dipping normal fault in the northern Basin and Range province. The Mw 6.9 1983 Borah Peak earthquake occurred on it and created surface rupture along the southern portion of the Warm Spring section and the entire Thousand Springs section of the fault (Crone et al., 1987; DuRoss et al., 2019). 
The Warm Spring and Thousand Springs sections are separated by the Willow Creek Hills, which form a structural boundary. We used unoccupied aerial systems (UAS) and a tethered "helikite" balloon to acquire aerial photographs, which were combined with ground control georeferencing to create two point clouds that model the topography at high resolution ( DSMs were generated from the point clouds, and orthomosaics of each area were made from the aerial photographs. The primary motivation for acquisition of the data set was study of the surface offset across the Willow Creek Hills structural boundary from the 1983 earthquake and prehistoric surface-rupturing events (DuRoss et al., 2019).
