Alaskan Yellow Cedar is fairly well described by its name alone. It is a cedar that grows from Alaska to Oregon and its wood has a yellow glow. The growing range of the Alaskan Cedar tree, being so far north, means that it grows very slowly. The wood can show as many as 75 rings per inch, compared to much faster growing trees in the continental United States. The wood obtained from these cedar trees is therefore fairly durable when exposed to the weather. This cedar was very available and affordable in the 1960's and 70's. Many fences in San Antonio were made from this wood. Much exterior millwork was crafted at the same time. At present, the woodwork on the exterior of the Alamo main chapel is of Alaskan Yellow Cedar, including the front doors. Many historic preservation rules state that work must be made to match the last restoration, so Alaskan Yellow Cedar is commonly used still on the Alamo.
