Preservapedia is a free-content encyclopedia and knowledge base. Unlike other online encyclopedias, Preservapedia focuses specifically on technical material related to cultural resource management and its allied fields. Questions, comments, ideas? Please contact us at info@preservapedia.org or check out the About page.

We want to create a community of preservation professionals to share their knowledge and expertise with the world. Building an encyclopedia is not an easy task but writing an article is. To get started, you may want to read the tutorial. Remember: the more you contribute, the better Preservapedia becomes.

Typical of this type of building, the intersecting log wall crowns extend 12" to 28" from the corners of the building. After about sixty years, decay had taken its toll. More than half of the extending crowns were so rotten that it was possible to pull large chunks of the heartwood out of the exposed ends. In the summer of 1986, the National Park Service repaired and selectively replaced the log crowns using epoxy and fiberglass reinforcing in a project costing $39,706. (Read more...)
