. However, the divide between the two river basins actually extends west and then north to a junction with the
Continental Divide at McNamee Peak.
For much of its length, it travels very roughly along the northern border of
El Paso County. Thus, it forms a natural separator between the Denver and Colorado Springs metropolitan areas. The elevation along the divide varies between about , with the high point being Bald Mountain in southern
Douglas County.

This terrain feature is the cause of several small scale (
microscale or
mesoscale) weather patterns and it can make a great difference in the weather between Denver and Colorado Springs. Although the elevation technically qualifies it for the foothills category, it does not parallel a mountain chain as foothills generally do; instead, the Palmer Divide is perpendicular to the main chain of mountains. Due to the orientation of the Palmer Divide with respect to the eastern plains, the weather can be similar to that of the
