Map of the study area. Eight study sites located within the North Saint Vrain Creek watershed (a) in the southeastern portion of Rocky Mountain National Park (RMNP), Colorado, USA^68,69 (b), where fire history is well documented by Sibold et al. (2006)³². The scale bar from 1 to 10 denotes kilometers. Denoted elevations of interest include the previously proposed shift in floodplain disturbance regime (~ 2300 m)¹⁴, the Pleistocene terminal moraine (~ 2500 m), the ecotone between montane and subalpine forests (2700 m), and the lower extent of the alpine zone (3400 m). An inset (c) illustrates an example of seven of the delineated 155 study reaches (denoted by bounding green lines) for which pre- and post-event lidar from State Route 7 to Ralph Price Reservoir was used to estimate floodplain erosion and deposition during the 2013 flood. The scale bar from 0 to 300 denotes meters
