Most Spiraled River Flow Route in USA - Counterclockwise Edition

Identified route includes 6 named canyons/creeks/rivers spanning 4 states.
Keywords: Geography Viz, United States Geography, Rivers, Spiral Drainage, Counterclockwise
Flow path: Colorado Plateau surface hillslope, Unnamed canyons, Dowozhiebito Canyon, Tsegi Canyon, Laguna Creek, Chinle Creek, San Juan River, Colorado River, Gulf of California
Total distance of flow = 1865.5 km (1159.2 mi)
States: Arizona, Utah, Nevada, California, and then into Mexico
Methods and Data Sources:
The “most spiraled river flow route” was determined by summing river reach line bearings from all order 1 segments to their most downstream reach using the MERIT-Basins vector hydrography database, which was derived from a 90 m global digital elevation model (DEM) (www.reachhydro.org/home/param.... Maximum and minimum sums represent most spiraled drainages in the clockwise and counterclockwise directions.
That hydrography data was downloaded for North America and clipped to the US for adding line bearing calculated geometry. Note that for computational expediency, intra-reach curvature was not incorporated in the calculations. These tend to largely cancel out at the large scale, but I acknowledge that a different solution might be found if intra-reach curvature was included in this analysis.
To extend the route further upstream, visual examination and drainage line delineation was performed using the USGS National Elevation Dataset (NED) 1/3 arcsec (10 m) DEM product. I tried to get to within a few pixels of what might be the most spiraled drainage route, but this part of the analysis introduced some subjectivity. I’ve also mixed scales in the analysis at this step. A different solution may emerge if the initial hydrography dataset was derived from a higher resolution DEM product.
Note that there is also a fractal-related issue with doing this kind of analysis. E.g. see this analogy in regards to measuring the length of coastlines: en.wikipedia.org/wiki/Coastli...

Check out the Nehelem River in northwest Oregon. It completes an almost full circle in much smaller distance. Starts on the eastern slopes of of the Coastal Range circles around and empties west into the Pacific Ocean at Nehelem Bay.

Love all your videos. Straight to the point with none of the typical creator-content flair that gets tiresome.

Topics for you: 1. Cave locations one can visit safely 2. Highest bridges over rivers 3. Indian reservations - what tribe and history 4. National parks - their history when each came about. 5. Number of tornadoes per year per state 6. Canals - when built and history 7. All the feeding tributaries for the Mississippi river 8. State capitals by size and history on their name 9. Meteor crater locations 10. Shipwrecks off the North Carolina - Outer Banks coast - they call this place the graveyard of the Atlantic.

If i had more time in my hands, i would do what you are doing in this video. I love geography

[@grandson_0623]

Very interesting

[@FLYBOYFANTASTIC]

You should do a list of average height of each state

You could do a great vid about the Salton Sea fiasco!

G-Viz - Love your stuff. Geography is destiny. Might you put a contact e-mail on your "about" page? Thanks!
