What do locals refer to the fertile upper slopes of Haleakala as?

The term "Upcountry" is commonly used by locals to refer to the fertile upper slopes of Haleakala. This area is characterized by its agricultural activity, with many farms and ranches taking advantage of the rich soil and favorable climate found in these elevated regions. The term captures the essence of the terrain, emphasizing its position above the lower coastal areas.

In contrast, other terms like "Downcountry," which could imply the coastal regions, do not accurately reflect the characteristics of the upper slopes of Haleakala. "Midlands" is not a term typically associated with this area in Hawaiian geography, and "Highlands" may refer to elevated regions in a broader sense but generally lacks the local specificity that "Upcountry" provides. Thus, "Upcountry" is the most appropriate and widely recognized term that locals use for the fertile upper slopes of Haleakala.
