Clifton sits at the bottom of a very tall staircase, about 4,700 feet on the valley floor with the Grand Mesa's rim more than a mile overhead, cool the entire time the valley bakes. Evenings, that high air slides down and the yards finally let go of the day. High Alpine Lawn & Pool Scapes LLC works into the cooling hour, mowing, trimming and running edges while the light goes long and gold across the grass. A lawn down here is a deliberate thing, and it holds up best cut on schedule and left tall enough to shade itself. Grass that feels good barefoot at eight in the evening has been looked after.
