In 1880, a California pioneer by the name of Pierre Cornwall and his wife Sada hiked from Glenwood, a small Santa Cruz Mountain retreat, over the southern slope of Mt Roberta and looked out over a vast, rugged mountainside that stretched out under a redwood blanket until it vanished into the Monterey Bay. The acreage on and around Mt Roberta's southern slope had it all: a view of the bay, cooling fog, seclusion, and unmatched natural beauty. In 1881 they purchased the property and named it Heart O' The Mountain. According to county records, they paid $500 for the 85 acre parcel. By 1887, Mr. Cornwall had established the vineyard and Santa Sada winery on the property, where the family produced wine until prohibition.
