Cheaper Logs by Skidding Both Down Hill and Up Hill
This article calls attention to possible reduction of logging costs by skidding both down-hill and up-hill to the same landing. The spacing of roads is thus widened and under certain conditions the decrease in construction costs exceeds the increase in skidding costs resulting from an up-hill pull. Ingenious formulae are presented with which to determine comparative costs and the most economical size and shape of the area to be served by a landing on both level and sloping ground. While there are limitations in any theoretical calculation, the methods used and formulae developed should be useful as a guide in most operations.
