There would not need to be any dislocations, adjust- <br />ments for loss of revenue, or re:cc:oticnc of any sort. There are usable <br />access roads already made from gravelled State roads, so no preliminary <br />road costs would be involved. The greater altitude and distance from <br />Basalt is not sufficient to increase the cost of mobilization or de- <br />mobilization, nor would it change the length of the work year.
