A small pass connects between the Kettle River basin and that of the Granby, where the town of Grand Forks lies immediately upon the border, and just east of which is the resort community of Christina Lake.
The area is rich with the sites of former towns and cities, most long defunct and nearly disappeared, although the names Kettle Valley, Boundary Falls, Anaconda, Phoenix and Eholt still appear on the map.
The Boundary Country was part of the traditional territory of the Sinixt, a First Nations people of the Interior Salish language group (also known as "Arrow Lakes" Indians).
In subsequent years followed the construction of the Dewdney Trail and, later on, discovery and industrialization of the area's rich mineral resources, notably copper.
Rock Creek, Midway, Grand Forks, Westbridge and Christina Lake enjoy a semi-arid climate with fairly low precipitation, mild winters and hot summers.
Higher elevation communities such as Greenwood, Beaverdell, Carmi, Christian Valley and Bridesville can also be considered semi-arid, but receive cooler temperatures and more precipitation, particularly snow.
