(4) Thence in a straight line due north to the intersection with the 1200-foot contour line in Section 18, Township 14 South, Range 6 East;

(5) Thence following the 1200-foot contour line in a generally northwesterly direction to where it intersects with the north boundary of Township 14 South, Range 5 East, Section 10; then following this boundary line in a northwesterly direction to where this boundary intersects with the 1600-foot contour line; thence following the 1600-foot contour line in a generally northerly direction to where it intersects with the unimproved road;

(6) Thence looping southward along the unimproved road and continuing on in an easterly direction past the designated “Spring” and then in a northeasterly direction parallel with the Gulch to the Vineyard School on Cienega Road; thence in a southeasterly direction on Cienega Road .4 mile to where the unimproved road intersects; thence traveling north and following the unimproved road in a northwesterly direction about 5. mile; then looping in an easterly direction .75 mile to the intersection of the unimproved road and branching in a southeasterly direction;
