Sign structures
Early information boards erected by the US National Park Service or Forest Service have provided models that have been frequently copied elsewhere. They were substantial structures with a heavy framework set in stone-built bases, topped by a shingle roof to protect the information panels located beneath. Some shelter or shade was also given by the roof to those reading the information.
Nowadays, while shade or shelter may be necessary in some locations, it is often better to keep the structure as simple and unobtrusive as possible, thus concentrating on the message and reducing the number of artefacts that the site has to manage and maintain.
Natural materials usually fit best into the wilder landscapes, although metal structures can have a purpose. Any structures need to be sturdy, easily maintained and positioned so that the message can be read by all, including children and people in wheelchairs as well as standing adults of varying sizes. This means keeping the structure fairly low while maintaining its visibility on a crowded site.
The following materials can be used.
