Our "Major Hazards" map contains the "full works" of features we have identified as suitable to put land forms into context. Showing you contours at 5m or 10m intervals, rocky features, major streams, woodland, major roads and railway lines, this map removes a lot of the "distracting clutter" found on more detailed maps. While we always recommend carrying a standard walking map as backup, this series is a perfect introduction to navigation by natural features.
