Loma Linda (Spanish for "Beautiful Hill")[6] is a city in San Bernardino County, California, United States, that was incorporated in 1970.

[6] The Tongva village of Wa’aachnga, or as the Spanish referred to it as the Rancheria Guachama, was located at what is now Loma Linda.

[8][9][10] In the late 1800s, Loma Linda began as a development of tourist halls called Mound City, as encouraged by railroad companies.

During the late 1890s, a group of businessmen and physicians from Los Angeles bought the Mound City Hotel and reopened it as a convalescent home and health resort.

[17] Loma Linda is located in southwestern San Bernardino County and is considered part of the Inland Empire.

It is bordered on the north by the city of San Bernardino, on the east by Redlands, on the west by Colton, and on the south by Riverside County.

An area of unincorporated territory in Riverside County separates Loma Linda from the city of Moreno Valley to the south.

The southern third of the city is known as the South Hills; this rugged and hilly area at the northwestern end of the Badlands is a city-owned open space reserve protected by a local initiative.

Ground water near Loma Linda is contaminated by a plume of the chemical perchlorate which was used in the manufacturing of solid rocket fuel.

This chemical was also formerly (decades ago and in very small amounts) prescribed by physicians to control the overactive thyroid glands of certain patients.

A nearby plant operated by Lockheed Aerospace has been implicated in the improper disposal of the rocket fuel ingredient, which leached into the ground water northeast of Loma Linda.

[24][25] Writer Dan Buettner has labeled Loma Linda a Blue Zone, an area where the longevity is appreciably higher than the national average and a substantial proportion of the population lives past 100 years.

[24][27][28][29] Loma Linda uses the council-manager form of government, and the City Council is composed of Mayor Phill Dupper, Rhodes Rigsby, Ovidiu Popescu, Rhonda Spencer-Hwang, and pro tempore Ron Dailey.

[35] Loma Linda is twinned with Manipal, India, and Libertador San Martin, Argentina, as its sister cities.

[36] Loma Linda University Medical Center is featured in Venom ER, an Animal Planet program focusing on snakebite treatment at the hospital.

[37] Former Loma Linda resident and heart surgeon Ellsworth Wareham was featured in the 2009 documentary film How to Live Forever.

In 1904, Seventh-day Adventist church guided by the visions of prophet Ellen G. White purchased a failed resort in the city to create a sanitarium and nursing school.
