Kevin Weiskoff, age 11, of Helena, Mont., for his question:

WHERE IS THE GREAT DIVIDE?

The Great Divide is the highland in North America that separates the waters flowing into the Atlantic Ocean from those flowing into the Pacific. This dividing line is also called the Continental Divide.

In the United States and Canada, the Great Divide is high in the Rocky Mountains. It also crosses New Mexico, Colorado, Wyoming, Idaho,

Montana, British Columbia and Alberta. In Canada the Great Divide joins the Height of Land, which separates Pacific and Arctic drainage on the west from Arctic and Atlantic drainage on the east.

The Great Divide also runs through Mexico and Central America.

Streams on one side of a divide flow in the opposite direction from the streams on the other side. The little streams are called the headwaters of a river system.

At Cutback Pass in Glacier National Park, there are three brooks so close together that a person can pour water into all three. One brook carries water to Hudson Bay, another to the Pacific Ocean and the third to the Gulf of Mexico. This point is actually the top of the North American continent.
