The topo lines are incorrect - the river does not rise and drop over a saddle where cliff walls have collapsed.

Check USGS maps of the area, satellite imagery etc, as well as some callborating photos in this comment https://www.reddit.com/r/GaiaGPS/comments/mdgvec/new_look_for_gaia_topo_layer/gsg7o19/?context=3

FYI the "way to red top" includes some very loose boulders in fine sand class 3, and red top itself has class 4 at least and shouldn't be marked as moderate (both are also very poor tracks as they're just lines between waypoints that don't accurately reflect terrain). Climbing routes should probably be disambugaited between more traditional class 1-2 (with maybe some moderate 3) social trails?
