The esthetic advantages of balloon logging are readily apparent from the air or on the ground as there are few scars left on the landscape compared to the conventional logging methods. This visual observation has proven true at tins site soon after logging and after several years have ]iassed since the logging tool place (fig- 3). Lifting logs vertically uith the balloon and flying them to the landing allows any cutting method to be used. On this sale, an overstory removal harvesting method was used with a minimum diameter specified, in order to release the understory. f!inimum diameter varied depending on tlie unit, but most units had a 13-inch (33-cm} minimum diameter. Very little damage to the understor)' resulted, and the majority of this damage occurred during the felling operation. A few limbs were broken by the main and haulback lines and flying logs, but this damage was minimal. A buffer strip of timber was left uncut, adjacent to stream channels in each log- ging unit. This was an effective method of protecting the stream, and the only apparent damage was due to a few logs being accidentally dropped into the creek during the yarding operation. Any debris from the logging was removed and the creek shows no effects from the logging. Figure 4 shows a t>q5ical reach of Anderson Creek as it was in August 1977. Landing construction was a source of ground disturbance. In order to minimize this disturbance, many of the landing areas were less than one-half acre (" ha) in size, or the road surface was used for a landing area (fig. S). A bedding area (fig. 6) was constructed in the Cow Creek subdrainage for tying the balloon down during severe storms or fo
