Greenhorn Mountain keeps snow in its high creases well after Colorado City has gone green, and the ground below is pinon, juniper and a wind that comes down out of the Wet Mountains most afternoons. A Cutting Edge Tree Service mows, edges and trims lawns through the Greenhorn Valley, where yards are carved out of rock and scrub and hold their ground by effort. Grass here is a decision somebody made, and keeping it takes a regular cut and a clean, deliberate border. Cleanups clear needles, leaves and the litter the wind stacks against a foundation. On a June morning with the mountain still white up top, a finished yard down here looks like a small, cheerful argument with the landscape.
