This map forms part of a series at 1:250 000 scale derived from the Provisional 1” to one mile ALC maps and is intended for strategic uses. These maps are not sufficiently accurate for use in assessment of individual fields or sites and any enlargement could be misleading. The maps show Grades 1-5, but Grade 3 is not subdivided.
