Walker Canyon (Riverside County, California)

Alberhill Canyon is an informally named valley and arroyo in the Temescal Mountains of Riverside County, California. It is named for the former mining settlement and populated place of Alberhill that lay opposite the mouth of the arroyo at its confluence with Temescal Creek.The canyon and the arroyo have their source is at 2,260 feet in the Temescal Mountains at 33°46′00″N 117°22′04″W, 3 miles east of Estelle Mountain. The arroyo is ephemeral, to its mouth in the wetter years, during the wet season in Southern California, otherwise being dry for the balance of the year. From its source Alberhill Canyon trends southwest to enter Walker Canyon 0.7 miles north northeast of Alberhill, California. From the canyon mouth it is a wash that runs down a short distance to a drain under the I-15 and to its confluence with Temescal Creek northeast of the old schoolhouse of Alberhill, at an elevation of 1214 feet at 33°43′45″N 117°23′39″W. Prior to the construction of the freeway the Alberhill Canyon arroyo ran into Temescal Creek in the vicinity of the drain, the creek was moved during the freeway construction to the south of the freeway.

Rice Canyon Creek is a tributary creek or arroyo of Temescal Creek in Riverside County, California. Rice Canyon Creek has its source at the head of Rice Canyon at an elevation of 3440 feet in the Santa Ana Mountains at 33°41′54″N 117°24′11″W east of the 4313 foot peak on the north south divide of the range. It is a wash that runs down from the canyon mouth 33°41′07″N 117°27′08″W at 1631 feet to its mouth at its confluence with Temescal Creek near Alberhill, California at an elevation of 1220 feet. Rice Canyon Creek has a tributary, Bishop Canyon Creek which enters the wash on the left a little below the mouth of Rice Canyon at 33°42′05″N 117°24′07″W.Rice Canyon Creek flows in the rainy season in its upper reach but is an ephemeral arroyo in its lower reach below the narrows 0.80 miles above the canyon mouth, and flows on the surface below the narrows only after more heavy rain events, and is dry the rest of the year. Rice Canyon's creek flows during the rainy season below its narrows to its mouth but its surface flow dries up below the narrows about 0.8 miles above its mouth in the canyon during the dry season, and above that in years with severe drought conditions. However some waterholes remain even in the dry years in the upper reach. Much of the wash in modern times has been interrupted by clay mining operations that stops the surface flows of water from Rice Canyon Creek from reaching Temescal Creek.

Terra Cotta is a former mining town in Riverside County. It was established in 1887, in the Warm Springs Valley northwest of the town of Lake Elsinore, and later incorporated into the City of Lake Elsinore. Coal, along with clay deposits, was found on the site by John D. Huff in the late 1880s, and the Southern California Coal and Clay Company was formed to mine them. The town site of Terra Cotta was laid out and was given a post office on October 26, 1887. However, in May 1893, its post office was closed and moved to Lake Elsinore. A plant for the manufacture of sewer and water pipes was built using the coal to fire ceramic pipes in the four kilns. The finished product had to be shipped by wagon six miles through Lake Elsinore to the La Laguna rail station at the mouth of Railroad Canyon until 1896, when a spur line was built through Lake Elsinore and Terra Cotta to the new clay deposits in Alberhill. The coal mined was also used locally as fuel for the stamping mill at the Good Hope Mine and was shipped elsewhere in the state. Almost abandoned in 1901, Terra Cotta was revived in 1906 when the California Fireproof Construction Company built a new plant there to make ceramic pipes. In 1912, the plant was closed; by 1925, it was closed down, along with most of the buildings in the town. The clay mine in the town site continued to be operated by the Pacific Clay Products Company until 1940, when they transferred all their operations to Alberhill. An old grid of dirt streets laid out through the sagebrush is all that remains of Terra Cotta. It can be accessed from Lakeshore Drive by Terra Cotta Road or from the I-15 freeway by Nichols Road.
