Plate 01: Topographic map of Abra
 

 
A partial scan of topographic map No. 2505 published by the old Bureau of Coast and Geodetic Survey in 1974.

The author superimposed colored areas outlined in yellow and principal town names in large notation for easy reference. 

Color Key:
Brown area: Ilocos Range Mountains
Green area: Cordillera Range Mountains

The shading highlights how geography contributed to develop the province along and up the Abra river from its outlet to the sea .

The town of S. Quintin is referred-to at times in the text also by its old name of Talamey.
