Map data consist of an orthophoto, a polyline shapefile delineating mapped surficial cracks, and a point shapefile showing the locations of crack width monitoring points (M1–M5) and a vibrating wire crackmeter. Monitoring data include four years of continuous crack aperture measurements from the crackmeter, periodic crack width measurements from M1–M5, and three sets of air temperature measurements recorded between 2018 and 2022. Air temperatures were measured at the surface and inside the crack at several depths throughout the monitoring period. 1. File List A.

E. Filename: CRT_crack_width_MP.csv Short description: 15 discrete crack aperture measurements made with a tape measure at monitoring points M1–M5 between 2018 and 2022. F. Filename: CRT_air_temp.csv Short description: Air temperature and relative humidity measurements collected near monitoring point M2 between June 2020 and April 2021. G. Filename: CRT_shallow_crack_air_temp.csv Short description: Air temperature measurements made inside the crack at depths of 1 and 2 meters (near monitoring point M2) from October 2018 to June 2020 and April 2021 to February 2022. H. Filename: CRT_deep_crack_air_temp.csv Short description: Air temperature measurements made inside the crack at a depth of 40 meters (near monitoring point M2) from June 2020 to April 2021. 2. Relationship between files: The locations of crack width, crackmeter and air temperature measurements are shown in CRT_monitoringpoints.shp. 3. Additional related data collected that was not included in the current data package: A 3-D model of the Courthouse Mesa rock slope instability is available from https://hive.utah.edu/concern/datasets/tq57nr07h. 4. Are there multiple versions of the dataset? No -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: We generated the orthophoto contained in CRT_orthophoto.tif using drone-based imagery collected with a DJI Phantom UAV. GIS data contained in CRT_crackmapping.shp and CRT_monitoringpoints.shp were mapped by hand during a field campaign in October 2019 and transcribed using ArcMap. Crackmeter measurements contained in CRT_crackmeter.csv were made at 30-minute intervals using a 100 mm Durham Geo Slope Indicator (DGSI) vibrating wire crackmeter and a DGSI VW MiniLogger. The crackmeter was set with an initial opening of 15 mm and the initial crack aperture was 250 mm. Crack width measurements at M1–M5 were made using a metal tape measure with a precision of ±2 mm. Surface and crack air temperature measurements were made using Onset HOBO Pro V2 temperature sensors. 2. Methods for processing the data: Drone-based imagery was processed using Bentley Context Capture to generate the orthophoto contained in CRT_orthophoto.tif. Raw crackmeter measurements were processed using the manufacturer provided polynomial coefficients to covert voltage values to distance measurements. 3. Instrument- or software-specific information needed to interpret the data: Crackmeter measurements contained in CRT_crackmeter.csv were made using a 100 mm Durham Geo Slope Indicator (DGSI) vibrating wire crackmeter and a DGSI VW MiniLogger. The crackmeter was set with an initial opening of 15 mm and the initial crack aperture was 250 mm. Surface and crack air temperature measurements were made using Onset HOBO Pro V2 temperature sensors. 4. Standards and calibration information, if appropriate: N/A 5. Environmental/experimental conditions: These datasets were collected in a natural environment and reflect multiple years of varying environmental conditions. 6. Describe any quality-assurance procedures performed on the data: N/A 7. People involved with sample collection, processing, analysis and/or submission: Erin K. Jensen, Jeffrey R. Moore, Paul R. Geimer, and Riley Finnegan collected field data and processed and analyzed the data.
