The name of the cemetery is Agua Mansa (sometimes spelled Aguamansa) and it means
Still Water (some say Healing Water).
It is located in Colton, California at the deadend of Euclid Avenue, I believe.

Subject: Slover Mountain

Yes, this is the mountain named after your, Eugene.

The Slover book says the mountain was one called the Place of the Ravens (I think).

This is Isaac, the son of John Slover the Indian fighter, captive, and Shaker.

Here are the notes I have for Isaac Slover including his will which describes his land.

It is not known just where Isaac lived before going West, as the census records, giving birthplaces of the children are never the same twice. But it was proably in KY and IN since when he moved West, he took the older children with him but left the twins with a brother. When the twins were about 10 years old, an older brother came from Arkansas to take them to join the family. This was about 1826; that was when Isaac's youngest brother, James, died in Vanderburgh Co., IN. His widow may not have been able to care for the boys any longer.

The following record from National Archives, Washington, D.C. may possibly belong here as Isaac was also known as Christobal and Louis. Christian Slover, private Carter's Regt., Militia, a company at Hamilton Dist., Terr., South of the Ohio, commanded by Nathaniel Taylor. Oct. 4 to 14, 1793. 11 days: $3 per month: $1, 10 cents.

Grant Foreman's "Pioneer Days in the Old Southwest" refers to that part of the Journal of the English naturalist, Thomas Nuttall when he describes his travels in the neighborhool of Fr. Smith, AR; "Nuttall went with two men in a canoe up Grand River for a visit to the salt works...they arrived at the home of a Mr. Slover, a hunter, who had a good farm on a fine elevation two miles below the Saline. The next day, he walked with Mr. Slover to see the salt works..."

Joseph J. Hill in "History of Warner's Ranch and Environs" says: "In Feb. 1824, Ewing Young, William Wolfskill, Slover and others fitted out a trapping party at Taos to trap on the San Juan and other tributaries of the Colorado or Rio Grand of the West as it was then called."

From Ingersoll's "Century Annals of San bernardino Co., 1769 - 1804, as related by John Brown, Sr.: "A party of free trappers of whom I was one, erected an adobe fort on the Arkansas River in Colorado for protection and as headquarters during the winter season. We call it "Pueblo" and the city of Pueblo now stands upon that ground. Into this fort, Christobal Slover came one day with two mules losded with beaver skins. He was engaged to help me supply the camp with game and during the winter we hunted together, killing buffalo, elk, antelope and deer. he would leave our camp and be gone for weeks at a time without anyone knowing his whereabouts and at last he did not return at all." In John Brown, Jr's History of San Bernardino Co. some of the members of the party of trappers were given as : James W. Waters, V.J. Herring, Alex Godey, Kit Carson, Bill Williams, Fitzpatrick, Bridger, Bill Bent, the Subletts and others.

From Bancroft's History of California, Vol III, p. 162-166. for 1835 to 40:

A resume. Sylvester Pattie and son, James, Ohio. Pattie headed a party of trappers on the Colorado, 1827. with a passport from the Northern Mexican custom-house, they started westward across the desert, having buried their furs. after terrible suffering, they reached Santa Catalina Mission in Lower (Baja) California, March 12, 1828. Ten days later, by Gov. Echandia's order, they were taken under guard to San Diego. The company included besides the Patties, Nathaniel Pryor, Richard Laughlin, William Pope, Isaac Slover, Jesse Ferguson, and James Puter. They were kept isolated until the buried furs were offered as ransom. they were released on condition that they return with the furs, leaving James Pattie as hostage. The furs had all been spoiled by the overflow of the river. Four of the six returned in September.; the other two left their companions on the Colorado and started for New Mexico. these two probably were Slover and Pope.

In November 1825, Isaac was issued a pass to go back to Sonora. In 1843, a party of colonizers from N. Mex., commanded by Don Jose Salazar arrived at La Politano and founded a village known as Agua Mansa (Healing Water). Isaac settled at San Bernardino at the south base of the mountain that bears his name.

From History of San Bernardino Co.: Isaac Slover married a widow with a family, Maria Barbara Aragon. There is a story about the mountain which may have some truth.

John Brown continued as follows: "Slover was a quiet, peaceable man, very reserved. He would heed no warning and accept no advice as to his methods of hunting. His great ambition was to kill grizzlies--he called them "Cabibs".

One day he went with a companion (James McMinds) up the left fork of Cajon Pass, almost to the summit. There they came across a large grizzly and Slover fired at close range. The bear fell, but soon rose and walked away and lay down in some bushes. Slover, after re-charging his rifle began approaching the monster, in spite of the objection of his friend. As the old man approached the animal it gave a sudden full spring upon him. The other man came down the mountain and told the tale and a party went back. They found Slover still alive but insensible. He was carried down to Sycamore Grove on a rude litter and there died.

The bear had done its work throughly.  The Scalp was torn from his head, his legs and one arm broken, the whole body torn and burised."

From Los Angeles Star, October 19, 1854; "The burial service was conducted by John Brown, his friend of Rocky Mountains days and some of the officials of the Mormon Church in the most orthodox style. The officiating priest was one of the sons of Captain Jefferson Hunt."

In 1931, Enoch A. Slover, a grandson, then living in Los Angeles tried to locate Isaac's grave.

Mr. George Beattie of Highland, CA gave the following in the San Bernardino Sun, June 29, 1931: "In the first place I will call attention to the fact that the pioneer Slover was known by several Christian names. In the census of Lost Angeles in 1844, he is named as a resident of San Bernardino rancho and is called Luis. His will, probated in a San Bernardino court, was signed Isaac Slover and in the burial records of the Agua Mansa Church he is entered as Christobal Slover. In all the records mentioned, his wife is called Maria Barbara Aragon.

Cerito Solo or Slover's Mountain, is the burial place of the old hunter; marked by a cross, due to the piety of Dona Barbara without doubt.

Apparently Slover's wife was not satisfied with the burial services for there is a record of a church burial of the body of Christobal Slover on October 24. Whether there was a disinterment and reburial, I do not know...Slover's grave was in the west end of the cemetery alongside of those of Louis Rubidoux, the Trujillos and others of the early settlers of the New Mexican colony.

A grass fire had destroyed the wooden crosses that marked the graves of the pioneers."

From John Brown, Sr.: "He was taken to his home and buried between his adobe house and the southeast base of the mountain."

                The City of Colton

encompasses an area of approximately 17 square miles and is located between the Cites of San Bernardino and Riverside, in the middle of the Inland Empire.

The City was formally founded in 1875 and incorporated on July 11, 1887.

However, its history goes back to the 1770’s when several explorers searched routes from Sonora, Mexico to Monterey, California bringing the first Europeans to the Colton area. Prior to this time, the Gua-chama, Serannos and San Gorgonio Indians inhabited the area.

By 1840 Colton was part of two privately owned ranchos, the Jurupa and the San Bernardino Ranchos. The southwest section of Colton is referred to as Agua Mansa (“Gentle Waters”); the area settled by New Mexico pioneers in 1842.

The town of Colton was laid out when the Southern Pacific Railway was constructed though the valley on its way eastward from Los Angeles in 1875.

Colton was named for Civil War General David Colton who was also Vice President of the Southern Pacific
Railroad Company.

Nicholas P. Earp, father of Wyatt, Virgil, and Morgan (among other children), was elected as Colton’s first City Clerk Recorder in 1887.

After Morgan was killed at the famous gunfight in Tombstone, Arizona, Virgil brought his body to Colton where he was buried in Hermosa Cemetery.

Virgil then lived for a time in the family home with his wife, Allie, which still stands at 528 H street.

Slover Mountain was named for Isaac Slover who settled on the south slope of the mountain 500 feet above the floor of the valley close to the Santa Ana River in 1841 or 1842.

In the late 1850’s, limekilns were operating on the north and west slopes of the mountain near the base.

Later, Colton Marble and Lime Company opened to be succeeded by the California Marble Company.

By 1881, the California Portland Cement Company started manufacturing there and was one of the earliest cement plants in the United States.

Throughout Colton’s history the Cement Company has always played a formative role in the local economy.

Another significant entity has been the railroad yard, one of the largest in the Western United States.

Other aspects of the historical local economy included fruit orchards and vineyards, along with related enterprises such as packinghouses, wineries, canneries, and seeding companies.

The population of Colton gradually increased from 400 in 1887 to 21,310 by 1980. Since that time, the population more than doubled to nearly 47,000 today.
