The entrance to the historic district is located directly west of the town of Oakville, California on Walnut Drive. Mature pecan trees planted during the first period of significance line the north side of Walnut Drive and continue along the driveway to the H. W. Crabb house, former gatehouse (Mehran House) and gardens. Directly west of the H. W. Crabb House is the site of the pre-Prohibition To-Kalon Winery, destroyed by fire in 1939. Infrastructure associated with the pre-Prohibition winery and vineyard operations still exist throughout the district including three stone bridges, a water system, and a loading ledge. The Spanish mission styled Robert Mondavi Winery was constructed in the northeast corner of the district along State highway 29. Five documented Native American sites are associated with the Wappo people. Thirty-two contributing resources include fifteen buildings, nine sites, and eight structures. Noncontributing resources—including fourteen buildings, two sites, and ten structures—postdate the second period of significance. Overall, the To-Kalon Vineyard retains its historic integrity of location, design, setting, materials, workmanship, feeling and association. ______________________________________________________________________________ Section 7 page 4 United States Department of the Interior National Park Service / National Register of Historic Places Registration Form NPS Form 10-900 OMB No. 1024-0018 To-Kalon Vineyard Napa, California Name of Property County and State Narrative Description Setting The origin of the To-Kalon Vineyard spans approximately 140 million years of geologic history.1 Weathering of these parent materials from the Mayacamas Mountains has deposited at the base of the watershed and created a complex of alluvial fans. Due to the limited depth of vine roots, the alluvium that grapes interact with has been deposited only in the last few thousand years. The soils are highly variable in their composition of coarse and fine material. Heavier materials deposit at higher concentrations at the base of the fans while clays and silts are typically carried further from the apex. Various contributing watersheds have deposited different concentrations of geologic parent material creating a diverse setting for agriculture. To-Kalon’s primary alluvial fan consists of three geologic parent materials in various forms. The upper reaches of the watershed include Franciscan Graywacke and melange dating to the early Cretaceous and late Jurassic periods.2 The largest component is composed of Great Valley Sequence, primarily sandstone and shale, dating from the same period. At the base of the watershed is a sliver of Sonoma volcanics from the Pliocene and late Miocene eras composed primarily of andesite and basalt lava flows.3 An outcropping of serpentine has been sliding towards To-Kalon Creek on the northern border of the watershed.
