By the last week of September the aspen up Thompson Creek have turned, and the gold comes down the drainages toward Carbondale a little further each morning. Treeline Landscape takes the season as it arrives: the final cuts kept a touch higher, edges tidied, then leaf after leaf gathered and carried off before the first wet snow mats them to the ground. Through the summer it is steady mowing and trimming, keeping the lawn even under a hard high-country sun. Spring brings the counterpart, clearing the yard of what winter dropped and shaping it up for growing weather. There is something clean about a raked lawn in October with the mountains going white behind it.
