This repository contains data and code for Speed et al., 2024. Structure-from-motion derived 3-D outcrop meshes are available for download on Sketchfab. Lidar data were acquired by the National Center for Airborne Laser Mapping (NCALM) and are hosted by OpenTopography. The notebooks folder contains Jupyter Notebooks for reproducing analysis and constructing/visualizing the 3-D stratigraphic model of the avulsion node. Model visualization relies on the stratigraph Python package.
