(7) Proceed southeasterly along Manton Ponderosa Way approximately 1.8 miles to the road's intersection with Rock Creek Road, and then proceed easterly on Rock Creek Road approximately 0.05 mile to the road's intersection with an unnamed light-duty road known locally as Forwards Mill Road, section 19, T30N/R2E; then

(8) Proceed easterly along Forwards Mill Road approximately 4.5 miles, crossing onto the Grays Peak map, to the road's intersection with an unnamed light-duty road known locally as Forward Road, section 26, T30N/R2E; then

(9) Proceed generally westerly along Forward Road approximately 4.8 miles, crossing onto the Manton map, to the road's intersection with an unnamed light-duty road known locally as Ponderosa Way, section 31, T30N/R2E; then

(10) Proceed southerly along Ponderosa Way approximately 1.7 miles to the road's intersection with an unimproved road (Pacific Gas and Electric service road, approximately 0.25 mile west-southwest of Bluff Springs), section 1, T29N/R1E; then

(11) Proceed westerly along the unimproved road approximately 2.2 miles to the road's intersection with the South Battle Creek Canal, section 3, T29N/R1E; then

(12) Proceed generally northwesterly (downstream) along the meandering South Battle Creek Canal approximately 1.3 miles to the canal's intersection with an unimproved road known locally as South Powerhouse Road, section 4, T29N/R1E; then

(13) Proceed northerly along South Powerhouse Road approximately 2 miles to the road's intersection with an unnamed light-duty road known locally as Manton Road, section 21, T30N/R1E; then
