These PNG images represent approximately 92 km of chirp seismic-reflection data collected by the U.S. Geological Survey during survey 2017-049-FA along the San Juan Arm and Good Hope Bay to Hite sections of Lake Powell in the Glen Canyon National Recreation Area. Images of each seismic profile were generated in order to provide portable and easily viewable alternatives to the SEGY versions of the data. Each profile image can be hotlinked to its corresponding trackline navigation contained within the Esri polyline shapefile '2017-049-FA_Edgetech424_Tracklines.shp'. Shotpoint index marks along the top of the PNG images correlate to the positions of 500 shot intervals within the Esri point shapefile '2017-049-FA_Edgetech424_500sht.shp'.
