The Flathead Indian Reservation Boundary cuts across the southern portion of this 1965 survey, marking a distinct line between tribal lands and the surrounding Flathead National Forest. This high-altitude landscape is defined by its glacial hydrology, featuring the Gray Wolf Glacier and a complex network of alpine lakes like Turquoise Lake, Crystal Lake, and the uniquely named The Angels Bathing Pool. The terrain is punctuated by significant summits including Gray Wolf Peak and the evocatively named Daughter of the Sun Mountain. Travel through these peaks during the mid-1960s was limited to a rudimentary network of Pack Trails, emphasizing the area's isolation within the Mission Mountains. The proximity of Giant Spring to High Park Lake suggests a landscape of active snowmelt and high-volume runoff feeding the headwaters of the Swan River.
