The data were collected to help identify the environmental controls on rates of rockfall, which is the primary source of debris-flow material at the site. Data were recorded at 1-minute intervals between November 2011 and August 2015. Data collection was occasionally interrupted during maintenance periods or when there was a problem with the power supply. Two probes measured profiles of rock temperature at depths of 0, 1, 2, 4, 8, 16, 24, 32, and 42 cm below the rock surface. One probe was placed on a south-facing rock slope, the other probe was on a north-facing rock slope. See photo \u201cSensorLocations.jpg\u201d for layout of sensors. Occasional malfunctions in the temperature sensor are identified by \u201cNAN\u201d readings or anomalous low temperatures (<-50 degrees Celsius). Time stamps are in standard Mountain time.
