Neat! I know there is a divide where I do a lot of my hiking/trail running. On one side, a raindrop would end up the Gulf of St. Lawrence, on the other, Chesapeake Bay... over 1100 miles apart. There is a point in northwest PA near the NYS border where the drop ends up either in the Gulf of St. Lawrence, Chesapeake Bay, of Gulf of Mexico: The hill is actually called "Triple Divide": I assume there must be a place out west were the drop ends up in the Gulf of Mexico, Pacific Ocean, and Arctic Ocean? |

Neat map. It is fun to fool with. I saved a link for future entertainment. I assume there must be a place out west were the drop ends up in the Gulf of Mexico, Pacific Ocean, and Arctic Ocean? I checked watershed maps and found that some of northern Glacier National Park flows into the Hudson Bay. But when I returned to this map and placed a drop there, it stopped at the Canadian Border. Darn customs agent, I suppose. I placed a drop north of Wamsutter, Wyoming (everyone has heard of Wamsutter, right?) and the drop disappeared into the dirt. |

Interesting. I placed a raindrop at the head of the Santa Cruz River in the San Rafael Valley in southern Arizona. The river flows south into Mexico then turns north and crosses the Border. It goes on north passing Tucson and eventually merges with the Gila River southwest of Phoenix.
The funny thing is that during the movie that follows, the track left the Santa Cruz river at the Border and followed the borderline to the west and picked up again where the Santa Cruz crossed the Border going north. I guess there must be some sort international agreement that prohibits the track from crossing the Border.

Thanks all. One feels good making others ply their fun. I dropped drips in a lot of places just to play around. Where I live, of course, all winds up in the Mississippi (lot of double letters- not a word for Scrabble wasting all those "ses"). But it was fun fooling around in the west and east. Too bad, covid limits crossing national borders. I wanted Hudson Bay for my drip drop.

It accurately shows a drop in the Colorado river never making it to the ocean. The track misses the actual path of the river in several places, but it's still interesting and fun.

Put a drop on the triple divide near Hibbing MN, and the drop could go to the Atlantic by three different routes: Hudson Bay, St. Lawrence through the Great Lakes, and Gulf of Mexico through Mississippi River.

I have to admit that I guessed wrong on the drip on the peak of my house's roof. I figured, given that the Colorado flows right through downtown Austin and, at least, seems closer than any other major river, it would go that way. But no, it follows multiple creeks and ends up in the San Gabriel and, ultimately, the Brazos. The Brazos goes through Waco, but it has deep, deep roots in this area.

I placed a raindrop at the head of the Santa Cruz River in the San Rafael Valley in southern Arizona. The river flows south into Mexico then turns north and crosses the Border. It goes on north passing Tucson and eventually merges with the Gila River southwest of Phoenix. Does it actually flow on the surface that whole way? I recall the parts I saw being dry, although it's a big channel in places and could have substantial flow in the subsurface alluvium. |

I'm pretty sure the map just follows the drainage based on the elevation differences. Free flowing water is not a permanent occurrence. |

It is kind of fun. I traced rain from my area; it runs NE to Lake St. Clair, then down into Lake Erie. It runs through 2 areas that are often mentioned when heavy rains occur, but I had assumed that those rains fell directly onto the 2 areas. I wasn't aware that the rain travels from the SW to the other areas.
