Howell Mountain (formerly, White Cottage) is an unincorporated community in the Vaca Mountains, within Napa County, California. It lies at an elevation of 1683 feet (513 m).
Howell Mountain was originally territory of the Wappo people. It was settled by European-Americans beginning in the 1840s. Wine grapes were first planted on the mountain in the 1870s by William Campbell Watson, grandson-in-law of settler George Yount. Numerous wineries and health spas were built in the area in the late nineteenth and early twentieth centuries.[1]
In August 2020, Howell Mountain was evacuated due to the Hennessey Fire, which resulted in the burning of over 3150000NaN0 in five counties, including near Howell Mountain.[2]
Howell Mountain is located 5.5miles north-northeast of Saint Helena.
For census purposes, it forms part of the Angwin census-designated place.
