Green arrives late at ten thousand feet and leaves early, which makes a Leadville summer feel like something borrowed. Black Hills Naturescapes works inside that narrow stretch — mowing, trimming, edging and cleanups packed into the weeks between the last snow off the ground and the first hard frost. Under Mount Massive the grass comes on in a hurry and the light is sharp enough to show every crooked line, so nothing gets rushed. A yard kept up here says somebody paid attention during the short run when attention counts. In July, with the peak still holding snow in its couloirs and the lawn cut even, that is a fine thing to stand and look at.
