Click to drop a raindrop anywhere in the contiguous United States and watch where it ends up

1. Zang! This is fun!

Thanks for posting!

[brer cat]

2. That is very cool.

[Kaleva]

3. Very interesting!

[MyOwnPeace]

4. Oh, SO cool!!!!!!

Wish I had had that when I was teaching Earth Science - of course now too many in the class wouldn't believe it anyhow....

5. Everything east of continental divide follows Platte R- Mississippi R. to Gulf of Mexico

as expected in Colorado. While everything west of the divide ends up in Colorado River to Mexico.

Pretty cool, though.

[Nittersing]

8. Well... everything east until the Appalachians nt

[hlthe2b]

9. I said in Colorado.

[Lochloosa]

6. click right below Jacksonville, FL and watch it flow upstream. St. Johns river runs North

[2naSalit]

7. Wow, that's cool.

I could have used that for my presentations back when I was giving them about the ecosystem.

[Lucky Luciano]

10. Definitely cool

11. it got my first try wrong

just before it went in to the San Pedro River it diverted UPHILL into an old irrigation ditch and went south a couple miles before entering the river at the intake of the ditch. oops.

21. It seems pretty "low-resolution"

I dropped one near my house and it did something very irrelevant... moved the starting point and just followed some river several miles away, when I'm practically on the body of water it showed it going to

24. Expand your view some more by tapping on the + sign on the upper left

There’s a wonderful topo map of my neighborhood, and hubby expanded it even further to show the roof of our house, realtor-style.

26. I meant the model rather than the imagery

I could zoom in to my house just fine. But when it ran the simulation it displaced my raindrop a few miles in generating that path!

29. Ah. The SoCal coast is so folded and uplifted, I ended up getting fascinated by the view ...

…that doesn’t show the houses. It was my husband who was trying to orient me better.

12. Thanks that was interesting and fun.

14. Mississippi to the Gulf of Mexico

So does this also apply to my late night pees outside with my dog?

[FoxNewsSucks]

15. That's really cool, someone has a lot of skill to create that

16. I keep clicking the Great Divide Basin. It shouldn't go anywhere but keeps

doing into to the Colorado River.

For those who don't know, there is a basin between the Continental Divide that splits the divide. If you were to fill it with water, ther would be a huge lake in south central Wyoming.

17. I love this! Thanks for posting.

We're surrounded by the Great Lakes so it's really fun to try different areas of the state.

18. I remember an anti littering commercial of a plastic bottle finding its' way from the city street to

some far off place and thought, "Nah, won't happen". Now I know it can. This is awesome! Thanks for sharing it!!!

[mountain grammy]

19. Excellent.. thank you!

[Pepsidog]

20. Cool

[Hekate]

22. Hours of fun!

Just emailed it to hubby so I can hang on to my iPad after showing him!

[ybbor]

23. That's very cool!

Saving for later

25. I picked a spot in WV just west of the eastern continental divide.

2,472 km to the gulf. Quite a ride.

[Rebl2]

27. Clicked

On a spot near KCMO and took forever to go down the mo river to Mississippi River to the gulf.

[jaxexpat]

28. I love this kind of stuff!

Click in Utah and Nevada to find the dead ends of a "Great Basin" system. It does tend to accept the closest data-based-included creek for the first leg of the drainage journey. I remember when I was a very young man reading a "Historic Marker" on a pretty isolated road in Potter County, PA. It said "Spring near here is origin of Allegheny river which flows into Ohio and then Mississippi rivers to the Gulf of Mexico. I could go on and on. It's a nerdish preoccupation.

[Laffy Kat]

30. That is so cool. nt

[LAS14]

31. Very neat!! Thanks!! nt

32. It's not real accurate for the watershed on my farm

It shows it going into Black Creek, then an "unnamed river/stream" then into Piney Z Lake - but the path it traces flows into Copeland Sink, which is known to connect underground into one of the springs for the St. Marks River.

Granted, the watershed south of here is very complicated with the various underground caverns that open into springs, but the path is is well known for this short watershed. This is one of the reasons I want to make my farm a conservation area and we made the subdivision behind us put a conservation easement on all the lowland that flows into Black Creek.
