Mackenzie Distributaries

Mackenzie Distributaries. Illustration of a complex network of meandering, branching river channels. The rivers are shown in dark blue, with colours ranging from light blue to white away from the channels. Lighter colours denote elevations that are higher than the nearest river channel.

commentsTried using the RiverREM package, but found more success following/adapting this tutorial. I suspect the 2 m resolution of ArcticDEM isn't perhaps high enough res for a good REM; and there's not much in the way of slope across this domain, so not a lot of elevation to de-trend; ~7 km across and ~10 km tall—probably should have included a scalebar; the typeface is nice, and suits the theme, but it is wholly unreadable
