Red Rock is a common name for landmarks in the American West. Today’s featured Red Rock is located in Washoe County, Nevada, north of Reno and south of Doyle. In 1867, Thomas Pearson and John Sutherland left Red Rock to relocate to Lower (Amedee) Hot Springs on the east side of Honey Lake. The following year, they planned to return to Red Rock, but were victims of what is known as the Pearson Massacre.
Sophus Petersen who had been in the Long Valley area, located on the abandoned Pearson & Sutherland property. Petersen, it should be noted was first married to Barbara Ross, whose father William and his brother Albert Ross ranch would eventually become Constantia.
On October 18, 2025 a historic plaque dedication was held at Rancho Haven Community Center to commemorate the history of the Petersen family and Red Rock. The pace reads as follows:
“Rancho Haven was originally part of the Red Rock Ranch, a family owned cattle grazing operation that covered tens of thousands acres or private and public lands marked by abundant springs.
“Danish emigrant Sophus Petersen was in the US by 1860 and by 1868 in the Red Rock area. He acquired land and built corrals, reservoirs and other features to convey water and manage livestock for his ranch. Sophus had four children: Ross, Sophie, Clara and Hedvig (Hattie). In 1899, Sophus died after being crushed by an overturned hay wagon.
“In 1900, Hattie Petersen married Owen Chapman Dickinson of neighboring Winnemucca Ranch. The Dickinson family added to the Petersen land holdings, built other structures, developed an airstrip an ran Red Rock Ranch for several decades. The family, ranch headquarters, and two reservoirs were located in the vicinity of today’s RHPOA Community Center.
“In 1966, Hattie and Owen’s son, Lawrence and his wife Judie sold all the ranch property almost 23,000 deeded acres with water rights, plus grazing and water rights for nearby public lands to a group of California/Nevada investors.
“In 1971, Occidental Petroleum Land Development Corporation about 4,000 acres from the group of CA/NV investors. Almost all this acreage became known as Rancho Haven. The Washoe County Board of Commissioners approved the final Record of Survey for the Rancho Haven residential development in July of 1971. Lot sales began soon afterward.
