noun / adjective
upland
UP-lund/ˈʌplənd/
Elevated land away from rivers or coasts, or relating to such land.
Grassy upland rises above the low river valley.

Etymology
Although up- and land suggest elevated ground today, upland first referred to the countryside or an interior district. The later sense makes relative height, rather than distance from town, the defining feature.
In context
Down in the creek-bottoms it was another country, the air hanging still and warm and heavy over the slow water long after the upland had cooled.
