Pinacate Mining District

Good Hope Mine was the principal gold mine in the Pinacate Mining District, Riverside County, California. Good Hope Mine was reputedly begun by a Frenchman named Mache, although the washes in the area were originally placer mined by Mexicans in the 1850s during the California Gold Rush using arrastras. The Good Hope quartz vein was found in 1874. Americans later bought the mine and worked it. The mine was worked to a depth of 575 feet, with several levels 100 feet apart below the 250 foot level. The first levels, at 250 and 350 feet, extended nearly 1,000 feet in length. The 450 foot level did not extend as far.The formation in which the ore occurred is a fine, even-grained granodiorite. At the surface were several veins at distances varying from three to twenty feet. At greater depth, these branching fissures united to form an irregular vein, with a tendency to send off shoots into the surrounding rock, chiefly into the foot-wall side. The foot-wall streak often contained high grade ore. The auriferous iron sulfide was finely disseminated through the quartz.In 1881 with the arrival of the California Southern Railroad nearby at Pinacate a five-stamp mill was constructed to crush the ore from the mine and developed the underground quartz deposit. In the 1890s an eastern corporation, the Good Hope Mining Company, took control and brought in a twenty stamp mill which was powered by coal from nearby Terra Cotta, California.Ore from the Good Hope was one requiring fine crushing and very careful amalgamation and concentration. After the installation of the twenty stamp mill, water supplies were insufficient for efficient operation of the mill. The four concentrating machines were in operation, with very poor separation of sulfides. Under such conditions, it would have been better to run a ten stamp mill, which would have allowed greater extraction and increased net profits. As a result of the diminished efficiency, the tailings carried sufficient value to make them profitable to cyanide operators who subsequently worked them. Had there been less desire to maximize the volume of ore running through the mill and greater attention to efficiency, there would have remained little profit for the cyanide man.The mine produced about $2 million in gold before 1896. The mine operated steadily until about 1903. An attempt was made in the 1930s by metallurgist James M. Hyde to reopen the mine. This effort was largely unsuccessful; the Good Hope Mine closed when it was flooded with underground water.The mine site is located between Lake Elsinore and Perris just west of Highway 74 between Richard and Eugene Streets. The mine workers settled in the area which took the name of the mine and is now a populated place to the north called Good Hope.

Temescal Mountains, also known as the Sierra Temescal (Spanish for "sweat lodge range"), are one of the northernmost mountain ranges of the Peninsular Ranges in western Riverside County, in Southern California in the United States. They extend for approximately 25 mi (40 km) southeast of the Santa Ana River east of the Elsinore Fault Zone to the Temecula Basin and form the western edge of the Perris Block. The Santa Ana Mountains lie to the west, the Elsinore Mountains to the south and the Perris Valley and Lakeview Mountains to the east.

Quail Valley is a former census-designated place (CDP) in Riverside County, California, United States. On October 1, 2008, the community along with the neighboring communities of Sun City and Menifee incorporated as the City of Menifee. The population when it was a CDP was 1,639 at the 2000 census.

Canyon Lake, sometimes referenced as Railroad Canyon Reservoir, is a reservoir created in 1928 by the construction of the Railroad Canyon Dam in Railroad Canyon or (San Jacinto Canyon) in the Temescal Mountains of southwestern Riverside County, California. The reservoir covers approximately 525 acres (212 ha), has 14.9 miles (24.0 km) of shoreline, and has a storage capacity of 11,586 acre⋅ft (14,291,000 m3). It is owned and operated by the Elsinore Valley Municipal Water District. The reservoir is supplied by storm water runoff from the San Jacinto River and Salt Creek. Water from the reservoir feeds the Canyon Lake Water Treatment Plant, which provides approximately 10% of the domestic water supply in the Lake Elsinore and city of Canyon Lake area. Canyon Lake has an average depth of 20 feet (6.1 m). Catch and release fishing is strictly enforced.

Warm Springs is a census-designated place in Riverside County, California. Warm Springs sits at an elevation of 1,365 feet (416 m). The 2010 United States census reported Warm Springs's population was 2,676.

Pinacate (Mexican Spanish word for the Pinacate beetle), was a small settlement east of the Pinacate Mining District in Riverside County, California. It was established when the California Southern Railroad line was built between Colton and San Diego in 1882. Due to a land title dispute the town was moved to the north to become Perris, California, in 1885. The Pinacate station remained and become the location of the Southern California Railway Museum, formerly named the Orange Empire Railway Museum. The Pinacate Middle School is in the area.

The Southern California Railway Museum (SCRM, reporting mark OERX), formerly known as the Orange Empire Railway Museum, is a railroad museum in Perris, California, United States. It was founded in 1956 at Griffith Park in Los Angeles before moving to the former Pinacate Station as the "Orange Empire Trolley Museum" in 1958. It was renamed "Orange Empire Railway Museum" in 1975 after merging with a museum then known as the California Southern Railroad Museum, and adopted its current name in 2019. The museum also operates a heritage railroad on the museum grounds.

Canyon Lake is a city and gated community in Riverside County, California, United States, located on Canyon Lake reservoir. Canyon Lake began as a master-planned community developed by the Corona Land Company in 1968. The City of Canyon Lake was incorporated on December 1, 1990. Railroad Canyon Dam was built in 1927, and impounds the San Jacinto River to fill the reservoir, which covers 383 acres (1.55 km2) and has 14.9 miles (24.0 km) of shoreline.

Warm Springs Valley is a valley located within the city of Lake Elsinore in Riverside County, California. It lies between the main body of the Temescal Mountains to the north, east and south and the Clevelin Hills to the west. The valley was named for the warm springs that used to be found flowing there. Warm Springs Valley is located along the upper reach of Temescal Creek near Lake Elsinore its upper point is where the Elsinore Spillway Channel emerges from the gap between the Clevelin Hills and Temescal Mountains 33°42′27″N 117°21′43″W, and runs northward to the head of Walker Canyon 33°40′47″N 117°19′43″W. Its easternmost point is the gap in the mountains where State Highway 74 passes to the east toward Perris 33°42′41″N 117°19′04″W.Three tributaries of Temescal Creek flow southwestward through the valley and under Interstate 15 into the creek. These are Wasson Canyon Creek to the south near the top of the valley, Arroyo Del Toro in mid valley, and Stovepipe Wash in the north in the lower valley above the Lake Elsinore Outlets.

Temescal Canyon High School is a public high school part of the Lake Elsinore Unified School District. Though it is located in Lake Elsinore, California, it also serves the areas of Canyon Lake and Horsethief Canyon. The school was opened for the 1991–1992 school year, graduating its first class in 1994.
