Geomorphic surface and channel boundaries for the lower 7.5 kilometers of the Taiya River Valley, southeast Alaska, 2018
This dataset presents boundaries and attributes of mapped geomorphic features in the lower 7.5 kilometers of the Taiya River valley bottom in and near Klondike Gold Rush National Historical Park near Skagway, Alaska. Geomorphic surfaces and off-main-stem channels were delineated from 2003 lidar elev...

Geomorphic surfaces and off-main-stem channels were delineated from 2003 lidar elevation data and updated using 2017 and 2018 aerial orthophotographs at eroding riverbanks, such that the dataset generally represents 2018 conditions. Interpretations of geomorphic surface age primarily used 2003 lidar data and aerial imagery from 1948 and 2003.
