Within each of these categories, there are several view types. The view types are defined as follows:

Significant panoramic background view - this view type consists of a view of an unobstructed or complete view of a large section of a mountain range. As a background, this scenery is set behind foreground and middle-ground views.

Uncompromised view - an uncompromised view provides a window, or "framed," visual access to a significant visual resource that is not compromised by structures or surface disturbance in the foreground or middle-ground.

View compromised by distant structures or surface disturbance - this type provides a window, or "framed" visual access to a significant visual resource that is compromised by structures or surface disturbance in the middle ground or near background.

View compromised by foreground utilities, signage, and structures - this type provides a window, or "framed" visual access to a significant visual resource that is compromised by above-ground utilities, structures, or surface disturbance in the foreground.
