Thus screamed a San Francisco Chronicle headline on February 8, 1889 when John B. Hobson’s application for a mineral patent the Excelsior Mine was approved by the Sacramento Land Office. The patent[1] included the core of the town of Iowa Hill, as shown in the photo, and would have potentially allowed Hobson, et al to hydraulic mine the townsite. How could this happen?

The Excelsior Mine, also known as “Lot 95, Section 33, Township 15 North, Range 10 East, MDBM,” appears to have included a drift mine claim, while the aboveground property was called a placer mine. The mine was first established in 1854 or 1855. The map shows the drift mine tunnels and shaft as of 1880.
John B. Hobson purchased rights to the Excelsior Mine placer claim in two transactions in 1885. An official survey of the mine was completed by E. C. Uren, US Deputy Mineral Surveyor, on July 20, 1885.

On April 16, 1887, Hobson, et al, (Hobson had two partners: Mike Gleeson and J. S. Lakin) filed M. A. [Mineral Application] 1,623 for a mineral patent of the Excelsior placer mine under the General Mining Act of 1872.
Since this property underlaid the bulk of the town of Iowa Hill. Judge B. F. Myers presented a pre-emptive application on June 21, 1887 for where the Iowa Hill townsite was located.
The Sacramento Bee stated that “Judge Myers represents, as trustee, the inhabitants of Iowa Hill. If Hobson wins it will be in his power to evict every person in the town of Iowa Hill or compel them to pay such tribute for exemption as his generosity might dictate.” However, Myers’ application was refused filing as it conflicted with Hobson’s. Initially, the matter was referred to Washington, DC, but was sent back to the Sacramento office.
On September 29, 1889 Selden Hetzel, Register[2] of the Sacramento Land Office, visited the site at the request of Counsel for both sides. He reported in a Statement by the Register issued on January 9, 1890 that “The slope of the country to the north and east of the tract in controversy, along … Main Street and Stevens Trails, afford abundant facilities for the maintenance of a business community much larger than that of the town of Iowa Hill as it at present exists.” In other words, Iowa Hill could easily move itself to the northeast! This doesn’t sound very unbiased.

The initial decision in Hobson’s favor was issued on February 6, 1890 by Seldon Hetzel, Register and J. G. Linthicum, Receiver of the Sacramento General Land Office (GLO).[3] The decision considered three factors:
- The agricultural value of the tract
- The value for municipal or residential purposes or as a site for a town
- The value of the tract for mineral uses
The supposed mineral value won out. The decision stated: “As to its mineral character, the great weight of evidence is direct and positive. A few of the contestants’ witnesses testify that the land possesses no value for mineral purposes, but their opinion is mostly based upon the results obtained in former years. Failure to obtain remunerative remunerative returns from hydraulic works thirty years ago is no criterion of the present value of land for mineral purposes. With improved machinery, with a lower rate of waste, with cheapened supplies, and with increased knowledge, land which, in 1857 and 1858 could have been worked only at a loss, may, perhaps, today be worked at a great profit. Some years ago all hydraulic mining in this vicinity, the debris whereof was carried into the North Fork of the American River, was enjoined by the Courts…” [italics added] The decision also dismissed Judge Myers’ application.

The map above was extracted from the 1890 Geological Map of the Iowa Hill Mining District, by John B. Hobson, and illustrates how much of the town was covered by the Excelsior Mine (red lines show the survey). This included the location of Colgan’s store, built in 1854 (and known as the “old store” in modern times until it burned in 1968), and the Macy store and home.
(Note that the map also shows the isthmus on the west side of town, where the Orion Mine Company almost hydrauliced away the road into Colfax before Charles Rice, owner of the road, sued in 1880 to stop them.)
The Iowa Hill residents appealed the ruling, and on June 21, 1890 the Commissioner reversed it. The Placer Herald reported that, “The two principal questions involved were: first, whether the attempted dismissal of the Townsite application by Judge Myers was effectual; and second, whether the land in contest is mineral or non-mineral.”
Now it was Hobson’s turn to appeal, and he went directly to the Secretary [of the Interior, bypassing the Sacramento GLO. On June 28, 1890, the Placer Herald reported that “Hobson now claims that the case was steamboated through at Washington, that a fair hearing could not possibly have been had, and he cites as evidence that the briefs on his side which were forwarded from here on the 2nd of June could not have reached Washington and been considered by the 9th, the day the case was decided against him.”
On January 28, 1892 Secretary of the Interior John F. Nobel reversed the decision yet again, in favor of Hobson.
At this point, the residents and business owners of Iowa Hill abandoned the GLO and sought contracts with Hobson which allowed them to continue to use the ground owned by Hobson in return for rent. Further, Hobson agreed that should he decide to hydraulic mine the property, he would compensate the townfolk for their improvements with the values to be agreed by arbitration. Eventually the rent was cancelled after the issue was taken to court.
In any case, the 1884 Sawyer Decision made hydraulic mining very difficult, so on March 18, 1892 Hobson testified before the House Committee on Mines and Mining in Washington in support of The Law to Regulate Hydraulic Mining in the State of California. His testimony was a major factor in the passage of the Caminetti Act of 1893, which allowed hydraulic mining operations to continue if the operators built and maintained impound dams to contain the tailings.
However, also in 1892, Hobson had transferred his mining interests to British Columbia, Canada where there were no restrictions on hydraulicing.
On January 19, 1906, the Sacramento Bee reported that “A suit has been filed in the Superior Court here by John B. Hobson to quiet the title[4] to certain land, which embraces the entire business portion of Iowa Hill, one of the pioneer mining communities of Placer County, and the action has revived an old controversy over the land in question.”
Nothing happened, however, until January 1910 when the Placer Herald reported that Hobson was considering building a dam in Indian Canyon so that he could start hydraulicing. Then on February 19, 1910 the Herald said, “[Hobson] has concluded not to hydraulic the gravel under that town as the amount of gravel is not sufficient the building of a retaining dam.”
Hobson died January 10, 1912 in British Columbia, but the patent stands. Theoretically, the current owner could still hydraulic the town. However, due to the 1897 and 1920 fires plus the burning of the old store in 1968, there are no longer any residents or business owners to protest.
The property appears, intact, in the Placer County Assessor’s map Book 64 Page 21as parcel #47. It has an assessed value of $20,576. The “pink house” property (parcel 21) is adjacent on the north side along Iowa Hill Road, and the “new” store (parcel 27) is located just north of that property. An extract of the page is shown here.

[1] A patent, unlike a mining claim, conveys full fee title (surface and mineral rights) of that land by the government to the holder, and converts it into private property.
[2] Each General Land Office had a Register and a Receiver. The Register handled all the administrative tasks, while the Receiver had fiscal responsibilities.
[3] Independent of Hobson but a necessary step, in December 1886 the Commissioner of the Sacramento GLO cancelled Section 33 from the list of odd-numbered sections granted to the Central Pacific Railroad under the 1862 Pacific Railway Act. This made Section 33 available for purchase or patenting.
[4] A quiet title action is a lawsuit designed to establish legal ownership of real property and eliminate any “clouds” (competing claims, errors, or liens) on the title.
