Guide Book No. 5: Excursions in the Western Peninsula of Ontario and Manitoulin Island; 1913

A classic early Geological Survey field guide, Guide Book No. 5: Excursions in the Western Peninsula of Ontario and Manitoulin Island (1913) was produced as part of a series of detailed excursion manuals intended for geologists working in the field.

The volume focuses on key geological localities across southern Ontario, including the Credit River area, Lake Simcoe district, and the Lake Huron and Lake Erie regions. It provides detailed descriptions of Silurian and Ordovician sections, glacial features, and classic stratigraphic exposures, many of which remain important reference localities today.

These excursion guide books are notably more specialized and locality-driven than standard Geological Survey reports, offering a practical, boots-on-the-ground perspective of early Canadian geological work. As such, they are very sought after by collectors, historians, and geologists with an interest in Ontario’s geological heritage.

This example remains in solid condition, with clean interior pages and only light wear to the original cloth covers.
