Imnaha is a scatter of homes along the Imnaha River at the bottom of a deep basalt canyon, a jumping-off point for Hells Canyon country. Namasa Landscaping brings landscaping and lawn care to this canyon-bottom settlement, where the canyon walls hold the summer heat and the river runs loud and clear. Their mowing and trimming let each yard sit easy beside the rimrock and the wild grasses climbing the slopes. In late afternoon, when the rims glow and shade pools on the canyon floor, a trimmed yard is a soft green note at the water's edge. It is patient work in a far-off corner of Wallowa County.
