Fourmile Canyon Wildfire Longitudinal Profile Data

This dataset represents 25 parallel longitudinal profiles that were extracted from terrestrial lidar point clouds taken during six survey periods. The six lidar surveys were conducted between 7 October 2010 and 8 October 2013. Over that time a colluvial hollow eroded into a fluvial channel. The longitudinal profiles show the topography of the colluvial hollow for each survey period. The width of the original colluvial hollow was approximately 1.25 m, and a longitudinal profile was extracted every 5 cm for the entire length of the hollow, resulting in 25 parallel longitudinal profiles. These data can be used to observe the transition of the colluvial hollow to a fluvial channel and furthermore they show the development of alternating steps and plunge pools. Within each of the 25 files, the column header describes the point number of the longitudinal profile, the distance downstream (meters), and the date of data collection. In addition, the file numbers represent profiles from west (1) to east (25).
