Harper and the surrounding agricultural landscape of Malheur County are defined by a complex irrigation network and historic transit routes. The presence of the Vale Oregon Main Canal and the Little Valley Lateral illustrates the engineering required to sustain settlements like Little Valley and Harper Valley in this arid region. The drainage of the Malheur River and Bully Cr provides the primary topographic relief, while several water sources like Alkali Spring and Harper Springs dot the terrain. For local historians, the map preserves the paths of early infrastructure, including the Old Stage Rd and Old Mail Rd, which parallel the river and modern thoroughfares. Near the river bend, the Harper Cem serves as a vital anchor for genealogical research in this rural pocket of Eastern Oregon.
