What significant area does the Baaj Nwaavjo I'tah Kukveni National Monument encompass?

The Baaj Nwaavjo I'tah Kukveni National Monument encompasses a significant area surrounding the Grand Canyon, reflecting the monument's purpose of protecting the cultural and historical landscape that is vital to the Indigenous peoples of the region. This area is deeply intertwined with the cultural heritage and practices of local tribes, embodying a landscape that holds spiritual and historical significance. By covering the surroundings of the Grand Canyon, the national monument ensures the preservation of these vital cultural resources and landscapes, which are integral to the identity of the communities associated with the area.

In contrast, the other options focus on either a single location, like the Grand Canyon itself, or specific locations that are adjacent or related to the monument but do not encompass the broader protective intentions of the national monument. The Kaibab National Forest, while adjacent, is a separate designated area. Similarly, the Havasupai Indian Reservation, though significant in its own right, is another distinct locale that is not representative of the larger protective goals of the Baaj Nwaavjo I'tah Kukveni National Monument. Thus, option B correctly identifies the expansive and inclusive nature of the monument's protective scope.
