The Mariposa Grove Comfort station was constructed in 1931. It is a sugar pine log building. Presently, the sill and spandrell logs are experiencing deterioration and will need to be replaced with in-kind material and corner notching. In addition, some of the other logs will need "Dutchman" repairs. The log crowns, just past the notches, have some decay and some of them will be replaced or repaired using preservation techniques. Any and all smaller cosmetic problems will be corrected during this project.
