Proceed straight east along the northern boundary of section 11 and then along the northern boundary of section 12 approximately 1.1 miles to the intersection of the section 12 northern boundary with an unnamed, unimproved road along Skyline Ridge, section 12, T9N, R13W;

Proceed generally southeast along the unnamed, unimproved road, on to the Tombs Creek map, approximately 1.3 miles to the intersection of that road with the 1,200-foot elevation line, section 13, T9N, R13W; then

Proceed generally southeast along the 1,200-foot elevation line approximately 0.6 mile to the intersection of that elevation line with Allen Creek, section 18, T9N, R12W; then

Proceed generally north along Allen Creek approximately 0.2 mile to the intersection of Allen Creek with the 920-foot elevation line, section 18, T9N, R12W; then
