This dataset provides supporting evidence for a method of generating geometrically accurate orthophoto mosaics of paleoseismic trenches using physical scale bars printed with coded targets. These data accompany a forthcoming study by Delano et al., 2021, Quick and dirty (and accurate) 3D paleoseismic trench models using coded scale bars. The data constrain three-dimensional models of a 46-m long, narrow trench excavation across the Teton fault (Wyoming, USA). Files include: BB_photos_nwall.zip: Photographs (n= 234) in .jpg format of the north wall of the Buffalo Bowl trench used to construct models. totalstation_control_modelpointcloud.laz: Structure-from-motion model point cloud of the Buffalo Bowl north wall,...

Text files: These data are text files of GNSS survey points collected along a trace of the West Napa Fault Zone near Ehlers Lane north of St. Helena, California. Data were collected to aid in paleoseismic investigation of the suspected fault strand and to characterize local geomorphology. Data were collected on March 31, and August 1, 2017 using a Leica Viva GS15 survey-grade GNSS receiver. The data are delivered as positions in the NAD83 UTM zone 10N coordinate system with orthometric heights according to Geoid 12B. LAZ files: These data are point clouds from terrestrial lidar data collected along a trace of the West Napa Fault Zone near Ehlers Lane north of St. Helena, California. Data were collected to aid in...

This data release includes field observations and laboratory data for two trenches excavated across the Lost River fault zone, Idaho, in September 2019. The field sites include the Sheep Creek site (44.282541 degrees N, 113.941193 degrees W) on the southernmost Warm Springs section and the Arentson Gulch site (44.247816 degrees N, 113.918554 degrees W) on the northernmost Thousand Springs section. Field observations include descriptions of stratigraphic units exposed in the trenches; laboratory data include 41 radiocarbon ages and 4 infrared stimulated luminescence ages.
