Carl Mengel was a prospector and miner in Panamint Valley, located in Death Valley National Park, California. He lost a leg in a mining accident, and continued to mine. He is the namesake for Mengel Pass in the Panamint Range. His ashes and prosthetic leg are buried on top of Mengel Pass in Death Valley National Park.
Carl Mengel was born in San Bernardino, California, in 1868. After various attempts at mining, farming, and fishing for a living, Mengel moved the Butte Valley region of Death Valley in the early 1900s. He is said to have purchased the Oro Fino Claim in Goler Wash in 1912, and later found even richer deposits there
Mengel was an early prospector in the Butte Valley area and contemporary and friend of such well-known Death Valley personalities as Shorty Harris and Pete Aguereberry. The site is located about one-half mile south of Anvil Spring and commands a grand view over Butte Valley toward the Amargosa Range on the east side of the salt pan.
.In October 1924 Mengel filed on several claims south and west of Anvil Spring: Topah Numbers. 1-4, Topah Extension, and Mah Jongg Numbers. 1-6. He died in 1944 and his ashes were put in a stone cairn atop Mengel Pass approximately fifty feet outside the boundary of Death Valley National Monument.
After his death the claims located by Mengel in Butte Valley underwent numerous resales through the 1940s, 1950s, and 1960s. The Topaz (Topah) Extension, Topaz (Topah) No. 1, and part of the Topaz (Topah) Extension claims were later amended and located as the Greater View Springs, Greater View Springs No. 1, and Greater View Springs Millsite, respectively.
