The rock this country is named for turns up everywhere once you notice it: pale Dawson sandstone under the scrub oak, the flat-topped butte down at Castle Rock, gravel in every dry wash. Rock Landscaping LLC mows the lawns laid out among all of that, where turf runs up against boulder walls and decomposed granite and has to be hand-trimmed to look right. Late-summer midday is bright and unforgiving at this altitude, and a lawn either holds its edges or it doesn't. Cut, trimmed, edged, blown clean; the difference reads from the street, and that is the point. Castle Pines, Castle Rock, and the yards along the ridges in between.
