The village of Topley is on the Canadian National railway, 285 miles west of Prince George and midway between Prince George and Prince Rupert. The area with which this report is immediately concerned stretches from Topley to the south, northwards about 12 miles; the width of the map-area is also 12 miles. The area was mapped geologically during the summer of 1928 with the aid of the topographic survey made during the previous year.
