Potrero Creek is a minor waterway of Riverside County, California in the United States. Potrero Creek has a 5-mile (8.0 km)-long course and flows south through the San Jacinto River basin. Potrero Creek drains about 35 square miles (91 km2) of the San Jacinto Mountains. Potrero joins the San Jacinto River near California State Route 79, at Gilman Hot Springs, California. There are reportedly a small group of cave shelters along Potrero Creek in Massacre Canyon, south of Beaumont, on what was called the Stanton Ranch in 1962. Massacre Canyon supposedly gets its name from a battle that took place around 1540, when Temecula people massacred defenders of a village (with associated chia plantings) of the tribe now known as the Soboba Band of Luiseño Indians, which was called Ivah and was located at what is now Gilman Hot Springs, California.

"The Hole" is the name of a detention building—also known as the SP Hole, the A to E Room, or the CMO Int trailers—operated by the Church of Scientology on Gold Base, a private compound near the town of Hemet in Riverside County, California. Dozens of its senior executives have been confined within the building for months or years. It consists of a set of double-wide trailers within a Scientology compound, joined together to form a suite of offices which were formerly used by the Church's international management team. According to former members of Scientology and media reports, from 2004, the Church's leader David Miscavige sent dozens of senior Scientology executives to the Hole. The Tampa Bay Times described it in a January 2013 article as: a place of confinement and humiliation where Scientology's management culture—always demanding—grew extreme. Inside, a who's who of Scientology leadership went at each other with brutal tongue lashings, and even hands and fists. They intimidated each other into crawling on their knees and standing in trash cans and confessing to things they hadn't done. They lived in degrading conditions, eating and sleeping in cramped spaces designed for office use. The executives confined at the Hole are reported to have numbered up to 100 of the most senior figures in Scientology's management, including the Church of Scientology International's President, Heber Jentzsch. Individuals are said to have spent months or even years there. After a few managed to escape the Hole and Scientology, they gave accounts of their experiences to the media, the courts and the FBI, leading to widespread publicity about the harsh conditions that they had allegedly endured. The Church of Scientology has denied those accounts. It says that "the Hole does not exist and never has" and states that nobody had been held against their will. However, it acknowledges that its members are subjected to "religious discipline, a program of ethics and correction entered into voluntarily as part of their religious observances".

Gilman Hot Springs, also known as San Jacinto Hot Springs or the Relief Springs, is a hot spring system in the Inland Empire area of Southern California. Located near Potrero Creek, the San Jacinto River, and California State Route 79, the springs system consists of "about half a dozen" springs named for the Mexican land grant Rancho San Jacinto Viejo.The springs emerge from a granitic alluvium formation that formed a marsh area. Gilman Hot Springs, along with Eden Hot Springs and Soboba Hot Springs, was one of a cluster of geothermally heated water sources along a fault line at the western base of the San Jacinto Mountains.

Gilman Hot Springs is an unincorporated community in Riverside County, California. It lies along California State Route 79, adjacent to the San Jacinto campus of Mt. San Jacinto College.

Gold Base (also variously known as Gold, Golden Era Productions, Int Base or Int) is the de facto international headquarters of the Church of Scientology, located north of San Jacinto, California, United States, about 85 miles (137 km) from Los Angeles. The heavily guarded compound comprises about fifty buildings surrounded by high fences topped with blades and watched around the clock by security personnel, cameras and motion detectors. The property is bisected by a public road, which is closely monitored by Scientology with cameras recording passing traffic. The property had previously been a popular Inland Empire spa resort called Gilman Hot Springs, which was established in the 1890s. However, the resort went bankrupt in the late 1970s due to changes in American vacation habits. Secretly bought for cash in 1978 by Scientology using the alias of the "Scottish Highland Quietude Club", it has since been developed and expanded considerably. Gold Base houses numerous Scientology organizations and subsidiaries, including its in-house media production division, Golden Era Productions, which has its own movie studio on the site. Senior church officials, and up to 1,000 of the church's elite Sea Org live and work on the base; the church's leader, David Miscavige, also lived there until reportedly relocating to Clearwater, Florida, in the late 2010s. It is also the location of a $10 million mansion built for Scientology founder L. Ron Hubbard. Although he never lived there before his death in 1986, the mansion and his living quarters are still maintained in anticipation of his predicted reincarnation. A number of prominent Scientologists have visited the base, notably Tom Cruise. According to some former members of Scientology, conditions within Gold Base are harsh, with staff members receiving sporadic paychecks of $50 at most, working seven days a week, and being subjected to punishments for failing to meet work quotas. Media reports have stated that around 100 people a year try to escape from the base but most are soon retrieved by "pursuit teams". Despite many accounts of mistreatment from ex-members, law enforcement investigations and lawsuits against Scientology have been thwarted by the First Amendment's guarantee of religious freedom and the church's ability to rely on "ministerial exemptions" in employment law. Scientology denies any mistreatment and calls the base "the ideal setting for professional and spiritual growth".
