This isolated region, long dependent on Lillooet and on the old Douglas Road and Pemberton Trail routes to the outside world, continued being considered part of the Lillooet Country until after the opening of Hwy 99 from Pemberton via Squamish to North Vancouver, since which time it has slowly become more identified with the modern-era Sea to Sky Corridor.
On the northeast, the edge of the Lillooet Country is marked by the summit of the Pavilion Mountain Road and the nearby eastern outlet of Marble Canyon.
Down the Fraser Canyon, a spot known as the Big Slide on Highway 12, or the southern outlet of Fountain Valley, form the southwest boundary.
On the northwest generally everything north to Churn Creek and Big Bar Ferry is considered to be Lillooet Country.
On the west, generally the summit of Cayoosh Pass on Highway 99 near Duffey Lake is recognizable as a "border" of the "modern" meaning of the Lillooet Country.
