The r.lfp addon is perhaps also interesting here: https://grass.osgeo.org/grass70/manuals/addons/r.lfp.html
Markus, Installed r.stream.distance, then r.lfp. Results:

I suppose that I can (again) completely re-project from the feet location to the meters location, but that takes many hours for the basic LiDAR DEMs (bare earth and highest hit).
