Early on a summer morning the water at Kenney Reservoir goes flat and silver, and the White River valley stays cool for about two hours before the light takes over. New Eden PCS uses that window in Rangely, mowing and trimming while the air still has some give in it. Yards out here fight wind and dry heat all season, so the cut is set high and the edges kept sharp to hold shape and moisture in the ground. Cleanups take out tumbleweed, blown grit and cottonwood fluff in spring, then leaves and spent growth in fall. What is left is a deliberate piece of green standing against a hundred miles of sage, which is not a small thing in this country.
