The Earth is replete with rivers, so much so that except for in some large deserts, you can not travel very far without the need to cross one. Even in the deserts, there are arroyo, gullies, and washes where water has flown before. Too, in most deserts today, the rivers still flow but only now underground.

So many are these narrow waterways that they are too many to count, so, methinks, there is need to categorize them just to be able to keep some semblance of recognition when arriving on the waterway in some future travel. Too, this gallery will begin with the Earth′s river on the North American continent.

Despite any personal disagreement on previous naming protocol, I will maintain the historical waterway names in this information gallery.

This first section will only list the main rivers into which many other rivers would merge or flow into. For lack of another designation, I will call these the primary rivers and those that merge into the primary rivers, will be called secondary rivers or tributaries.

The primary rivers listed below, with only a very few exceptions will be those that flow into a large lake, a gulf, a bay of an ocean or directly into an ocean. These primary rivers will be listed under the state from where the mouth of that river is found. For instance, the Colorado river mouth will be listed in Baja California (31.6865575, -114.7079411) and the Rio Grande river mouth will be listed as Texas (25.9571752, -97.1473493)

Primary Rivers include all of the first level below each state and Secondary Rivers which are tributaries of a primary river are indented beneath the primary.

The miles that are listed next to the name of a river is the length of the river from original headwaters (fork in the river, lake, or spring) to the outflow point (bay, gulf, ocean or primary river.)
