Which states are consistently included in the region where the Cayuse War took place?
Northwestern United States The Northwestern United States is an informal geographic region of the United States. The region consistently includes the states of Oregon, Washington, and Idaho—and usually Montana and Wyoming. Some sources include southeast Alaska in the Northwest. The related but distinct term "Pacific Northwest" generally excludes areas from the Rockies eastward.
Upstate New York Upstate New York is the portion of the American state of New York lying north of the New York metropolitan area. The region includes most of the state of New York, excluding New York City and its environs, as well as Long Island, though the precise boundary is debated. Upstate New York includes the major cities of Buffalo, Rochester, Albany, and Syracuse.
