This dataset contains 2053 records in 16 fields, reporting the location, geometric characteristics, VS, and related parameters of measured faults ruptures and Quaternary fault scarps from the Lost River Fault, Idaho, USA.

Fault segment name: Text indicating the acronym of the fault segment along which the measurement was acquired; (Challis Segment = CS; Warm Springs Segment = WSS; Thousand Springs Segment = TSS; Mackay Segment = MS; Pass Creek Segment = PCS; Arco Segment = AS; Lone Pine Fault = LPF).Topographic profile ID: Number indicating topographic Profile ID (Topographic profile ID listed in the "Topographic Profiles dataset") along which the measure was acquired.Synthetic/Antithetic (short name: Syn/Ant): The Lost River Fault is a SW-dipping fault; This field summarizes the information obtainable from the dip direction of each trace, as it categorizes all the traces with the same dip direction of the LRF (synthetic) and all the traces with dip direction opposite to the LRF (antithetic).
