Utah to Washington
Mountain Dell Dam, Salt Lake City, Utah.
The development of the multiple-arch reinforced concrete dam by engineer John S. Eastwood took advantage of the inherent characteristics of an ancient building form to greatly reduce the needed mass of dams. Inclined, reinforced concrete barrel vaults transfer the weight of the impounded water to the ground through a series of buttresses. The downward pressure actually increases the stability of the dam by pressing it against its foundation, making it an ideal design for poor foundation conditions. Eastwood built similar dams throughout the world.
Job Lyman House, Woodstock, Vermont.
Job Lyman, a young lawyer from Northampton, Massachusetts, finished this house in the village of Woodstock in 1810. He and his bride, Mary Hall, lived in it for many years while Job practiced law in town. The finely carved Neoclassical detailing on the entrance porch suggests Lyman's refined taste and the prosperity of Woodstock at the time of construction. Decorated with fluted Ionic columns and scrolled ornament, the porch also features steps made of granite from a nearby quarry.
Monticello, Charlottesville Vicinity, Virginia.
President Thomas Jefferson designed his home, Monticello, as a sophisticated and innovative structure that could serve as a model of architecture for his fellow countrymen. Constructed between 1768 and 1809, Monticello has become known as one of the greatest works of western architecture, being designated as a World Heritage Site in 1987. Much has been written about Jefferson's passion for architecture and the antecedents for his designs. Floor plans and photographs of the house have been widely published, but it was not until the HABS section drawings were produced that one could illustrate how the geometrically complex spaces integrated vertically.
Schooner Wawona, Seattle, Washington.
Historic ships are among the most difficult objects to preserve and few vessels survive long enough to be considered historic. Those that do require expensive maintenance to be operational. The 1897 schooner Wawona was put into a floating dry dock in 1985 to allow necessary periodic repairs to the wooden hull. While the hull was accessible, HAER measured and mapped the shape of the hull in a series of topographic drawings, a process called "lines-lifting." This lumber schooner was the first project of HAER's ongoing maritime program.
