Small sub-AVA within the Russian River Valley AVA in the foothills on the far eastern boundary of the district near the town of Windsor. Some objected to its inclusion in the Russian River Valley AVA, arguing that its location on the western slope of the Mayacamas range and its volcanic soils mean that it has little in common with the gravel and sandy loams more common in the valley below. Yet studies of the daily Pacific fog incursions that define Russian River showed that they reached into Chalk Hill, and it remains in the larger AVA. Chalk Hill Estate is the dominant winery, and growers have had success with Chardonnay, Sauvignon Blanc, and Cabernet Sauvignon
