Found a use for all that public LIDAR: paleo-waterfall detection in northern California
I'm trying to learn QGIS to create visualizations. This is output from a detector I built that flags candidate paleo-knickpoints in stream networks. The idea is to find places where a former waterfall has migrated upstream and left its plunge pool behind. The colored dots are sample points along auto-extracted channels, graded by score (blue/green low, red high). White X marks are the candidate knickpoint locations themselves. Basemap is the hillshade.
