Oxford Tree-Ring Laboratory - Virginia
Here seven samples were taken from five timbers, four of which were pine and one of oak. The oak timber did not retain complete sapwood, but produced a last measured ring date of 1828, matching well with the oak samples from the Ice House as well as the other Headquarters master chronologies. Only two of the pine samples dated, but fortunately both retained bark edge and produced precise felling dates of summer/autumn 1835, and winter of 1835/6. All of this evidence suggests a construction period of 1836 or within a year or two afterwards.
