Many noted fur trappers and traders are reported to have been familiar with the headwaters of the Grand (Colorado) River as early as the 1820s. Among them were Thomas Fitzpatrick, Jim Beckwurth, Christopher “Kit “Carson, Henry Fraeb and Peter Sarpy. Louis Vasquez built a trading fort on the South Platte River and ventured into what is now Grand County, where a pass east of Berthoud Pass is named for him.

His partner, Andrew Sublette, also came across the Divide to trade in Grand County, as well as Ceran St. Vrain, whose fort was near modern Platteville. 26 year old Tom Smith was with a group of trappers who entered the northern part of Grand County in 1827, where they were attacked by either Ute or Arapahoe Indians. Tom was hit in the leg by an arrow, splitting the bone and creating a life threatening infection. Amputation was needed but none of the party had the nerve to perform the operation. So Tom took a butcher knife and amputated his own leg. As “Pegleg Smith” Tom later became noted as one of the greatest horse thieves in the West, but was never prosecuted.

The beaver trade was essentially over by the 1840s as silk replaced beaver pelt as the stylish material for top hats. In 1842, famed traveler Rufus Sage came over Muddy Pass into Middle Park, but recorded almost no hunting activity there. On the other hand …fishing was great! His party caught over 50 pounds of trout in one morning. Noted mountain man Jim Bridger and another guide, Joseph Chatillon, let the infamous Sir George Gore on an extravagant hunting expedition in Middle Park. Despite the senseless slaughter of thousands of game animals, Gore has been immortalized with a mountain range, canyon and pass named for him.

One of the earliest of the mountain men to discover what was to become Grand County arrived in the Fraser Valley as early as 1860, soon after gold was discovered in Colorado. Charley Utter, known as “Colorado Charley”, was considered the prototype of rough trappers and traders. He was unique, though, in that he insisted on taking a bath every day, whether in the hot springs or beneath frigid waterfalls. In 1864, Charley was one of the first to make use of Berthoud Pass driving cattle that he raised at Troublesome Creek. His home was host to various adventurers who came to explore the prospects of Middle Park. He would eventually work with the famous Buffalo Bill Cody, appearing in “Wild West” shows.

When Kentuckian Beverly D. William spent some time in Grand County, he realized the Grand River was originally named the Colorado. As a Washington delegate from the newly organized “Jefferson Territory” (as this area was known at the time), he was instrumental in getting the named changed to the “Colorado Territory”, although the river was called Grand River until 1921.

The Wolverine Mine was discovered in 1875 by James Bourn and Alexander Campbell. Bourn was the brother-in-law of James Crawford, the founder of Steamboat Springs. James Bourn was the twin brother of Crawford's wife, Maggie.  A Grand County recording error forever changed the name of Bourn in the area to "Bowen".  The mine was located in the Rabbit Ears Range on Bowen Mountain, up Bowen Gulch, approximately 10 miles northwest of Grand Lake.  This discovery sparked additional exploration in the area that lead to a number of new mines. Within a week of the original discovery,  interested parties formed the Campbell Mining District which included Bowen Mountain, Bowen and Baker gulches.  Some of the Middle Park residents who participated in the mining exploration  were John Baker, Charles Royer, Charles Hook, John Stokes and the Redman brothers, William and Mann. The Redman's  eventually  discovered the Sedalia mine. Bourn and Campbell  in less than a year lost the Wolverine mine by not fulfilling a grubstake agreement with the Georgetown grocers, Spruance and Hutchinson.

John Stokes leased the Wolverine Mine from the grocers until Edward Phillip Weber, an agent representing a group of Illinois investors, purchased the Wolverine Mine in the Summer of 1879.  Weber continued purchasing other Campbell Mining District claims which created a great deal of local excitement.  Weber hired Stokes  to assist him and also hired Lewis Dewitt Clinton Gaskill to act as the first foreman for the Wolverine mine.  Gaskill had mine operation experience, having successfully operated the Saco Mine, on Leavenworth Mountain, above Georgetown for several years.  A mining camp was built  below the Wolverine Mine that contained a large bunk house building and a more substantial mine office building.

Gaskill, a Civil War veteran of the 28^th  Regiment of the New York Volunteer Infantry,  had come to Colorado in 1868 as a representative of a group of Auburn, New York bankers to invest in mining properties.  He eventually successfully operated the Saco mine in 1873 and 1874.  He invested in the Georgetown, Empire and Middle Park Wagon Road in 1874, which was a toll road that finally made the Berthoud Pass road passable for wagon traffic.  Gaskill also acted as the foreman during the construction of the road. The principal investor in the road was William Cushman of the First National Bank of Georgetown. The bank had a financial collapse in 1877.  At that time, Gaskill was the secretary of the road company and lived with his family in the company house just below the summit of Berthoud Pass on the west side.  William Hamill, a wealthy Georgetown businessman, bought the wagon road in a foreclosure auction in 1881 for $7,000.  Gaskill continued to live with his family in the Berthoud Pass summit house until 1885, when he moved his family into the Fraser Valley and homesteaded 160 acres along Elk Creek.

The settlement of Gaskill began when  in August of 1880,  Al J. Warner built a log cabin store in a meadow below Bowen Gulch on the trail/road that lead to both Bowen Gulch and Baker Gulch.  The settlement was also strategically well placed midway on the trail/road between Grand Lake and Lulu City and the Lead Mountain Mining District.  Another store was built in September by  John K. Mowery.  By that October, Mowery was appointed as the first postmaster of Gaskill.  The following spring E. Snell, opened a large general merchandise store that prompted the original store keeper, Al Warner, to relocate to Grand Lake as Al's Place. The town was named to honor L.D.C. Gaskill, the greatly respected foreman of the Wolverine Mine, the road builder/operator and the Civil War veteran.  By 1882, the town covered 60 acres.  E.P. Weber of the Grand Lake Mining and Smelting Company got involved in the town real estate development by laying out a city grid and offering lots for sale.  Weber's plat renamed the town Auburn after L. D. C. Gaskill's home town of Auburn, New York, but the Gaskill name stuck.  By the close of 1882, there were over 100 residents living in Gaskill.  The most substantial building was the Rogerson House, a well appointed two  story, squared log hostelry, Horatio Bailey Rogerson, proprietor.  Rogerson, would be elected County Commissioner in November of 1882, but would not serve because of a sudden discovery of ineligibility.  Instead, lame duck Colorado Governor Pitkin, appointed E. P. Weber to the post.  Weber was killed in the infamous July 4, 1883 shoot-out at Grand Lake.   

The Bowen Gulch trail lead to many of the  most productive and worked mines in the Campbell Mining District which included the Wolverine, now owned by the Grand Lake Mining and Smelting Company, E. P. Weber superintendent and the Ruby and Cross mines owned by Kentucky and Colorado Mining and Smelting  Company, John Barbee superintendent. Barbee, who lived in Grand Lake,  would go on to serve as superintendent of schools, Justice of the Peace and briefly the editor of the Grand Lake Prospector.  Barbee's partner in many endeavors was Antelope Jack Warren. Warren was as rough as Barbee was refined.  He acted as a foreman and, by one account, a bodyguard for Barbee.  The Bowen Gulch trail continued up the mountain to Bowen Pass and then descended into North Park and the Jack and Park mining districts which were organized by the end of 1880, to the settlement of Teller City.  Passable roads that could handle wagon traffic were needed and often planned but rarely built.  The high cost of building and maintaining  wagon capable roads in Middle Park was a difficult proposition for local governments and private entrepreneurs.  

The Grand County Commissioners in July of 1877 had declared the trail from Grand Lake to the mining gulches of the Rabbit Ears  Range to be a county road.  However there was little county money to pay for improvements to make the trail a road.  Private investors were reluctant to invest in wagon roads when there was the persistent  rumor that railroads were coming spawned by the numerous railroad surveys that were performed in the area.   Albert Selak, a Georgetown brewer, in August of 1878, organized a toll road that would branch off of the Georgetown, Empire, and Middle Park Wagon Road at the Ostrander Ranch on Red Dirt Hill, and proceed to Grand Lake and continue on to the Rabbit Ears Range mines and continue on into North Park and on to the Wyoming territory line.  John Barbee invested in the Middle Park Toll Bridge Company, a toll bridge company that intended  to build a bridge across the Grand River  above the confluence of Willow Creek and the Grand River.  However, this project languished, and was taken over by the county with an expenditure of $150.  

If ore wagons would need to haul ore to the nearest reduction mill which was over 60 miles in Georgetown, the toll road might have been a financial success. However, the lower grade ore from these Rabbit Ears Range mines would not yield a sufficient profit to cover the transportation and processing costs in a market where the market value of silver annually declined.  So the ore piles grew.  What was needed was a nearby reduction mill or cheaper transportation, like a railroad or a higher price for silver.  Weber had  repeatedly promised that a reduction mill was coming, but nothing was ever built.  By April of 1883 with tons of ore piled up and waiting for transport to be processed,  Weber temporarily closed the Wolverine Mine and laid off his miners.  He admitted  in June of 1883 that the ore from the Wolverine was “rather refractory” and that it would not justify shipment without local reduction.  Some hoped the closing was a strategic move by Weber to trigger a sell off of area mining properties  so that he could acquire additional mines before he built the reduction mill, but it was not to be. Weber would soon be shot dead by his political rival, John Gillis Mills.

The favorable newspaper stories of Rabbit Ears Range mining would continue, but for the informed, it had become  clear that without a major investment in improved transportation including a railroad or a major investment in a reduction mill in the area, the mining concerns were doomed to fail.  Mining claims had to be worked in order to be kept.   A minimum of $100 of labor or $500 in improvements had to be expended each year to maintain the claim or else the claim would be deemed abandoned.  Many claim holders leased their claims to miners to work for a percentage of the return.  Without the ability to sell and process the ore for a profit, there was no return.  The speculative mining investment money began to dry up and the miners and their supporting merchants began to leave.  By the end of 1886, the Middle Park mining boom had  ended. To further add to the decline,  a border dispute that arose between Larimer County and Grand County over the taxation and mineral wealth of North Park was finally decided in 1886 by the Colorado Supreme Court in favor of Larimer County.  North Park was part of Larimer County, not part of Grand County.  A lawsuit would follow so that Larimer County could recover the wrongly collected taxes of $20,000 from Grand County.  Grand County's total tax income at the time was less than $3,500 a year.

Granby Hillyer was born in Cartersville, Georgia on July 7, 1874. The third of six children, born of Shaler Granby Jr. and Lelia (Holloway) Hillyer, and the grandson of the Rev. Shaler Granby Hillyer, Sr. who was born in Granby, Hartford County, Connecticut. When Granby was 13 years old the Hillyer family moved to Washington, D.C. where Granby graduated from public high school. He then entered government service and at the same time studied at George Washington University, receiving a Bachelors of Law Degree. A postgraduate law degree was awarded in 1896 from Columbia University School of Law. He moved to Colorado in 1898 settling at Lamar (Prowers  County) launching a 40+ year legal career. On June 16, 1900 he married Miss Annie Creaghe, from a prominent southern Colorado pioneer family, and a daughter of an Apache County, Arizona sheriff. To this union were born 3 children St. George Creaghe, Granby Francis Ridgeway Jr., and Helen Edna Dolorine (Jane) later Mrs. Albert Hunt of Boston, Massachusetts.

Granby Hillyer was a member of the Republican Party. He served as Lamar City Attorney, Prowers County Attorney, and Deputy District Attorney. He was also affiliated with the Elks, Masons, Sons of the American Revolution, and Woodmen of the World fraternal organizations.

At 28 years of age, the citizens of Prowers, Baca and Las Animas Counties, elected Granby Hillyer to serve in the 14^th Colorado General Assembly, House of Representatives, making him one of the youngest elected officials in state legislature history. He served one term from 1903-1905. During this tenure he plotted the streets at no cost for the Frontier Land and Investment Companies newest town on the Denver, Northwestern & Pacific Railroad (The Moffat Road). In doing so, Mr. Hillyer was honored by having the Town of Granby, Grand County, Colorado named for him.

Governor Carlson appointed Mr. Hillyer as the Third Judicial District Court Judge, at Trinidad, Colorado from 1914-1916. Her served as the United States Attorney for Colorado from 1922-1925. Afterwards he enjoyed a large private law practice in Lamar and Denver.

In 1928 at Lamar, Granby Hillyer was a speical prosecutor in the "Fleagle Gang Case".  On May 23rd, the First National Bank was robbed, resulting in the loss of four lives.  The case has been credited by the F.B.I. as the first robbery solved from a single fingerprint.

The Denver Post on July 21, 1931 page 9, reported "Granby Hillyer Is Disbarred By Federal Courts." In a decision reached by the United States Circuit Court of Appeals, predicated by a Colorado Supreme Court tribunal, of neglecting the interests of his clients in a number of cases.

Tragedy then struck the Hillyer family twice with the loss of St. George Creaghe in June 1932 and October 1933, Granby Jr. was killed in an automobile accident near Lamar. They both were attorneys. St. George and Granby Jr. were born 16 months apart and passed away 17 months apart. Both funeral services were held at the Immaculate Conception Cathedral in Denver, with the same set of pallbearers for both young men. They were laid to rest at Denver's Fairmount Cemetery. Their father Granby Hillyer, joined his sons on January 2, 1942, passing away at Denver Mercy Hospital, after suffering a heart attack at age 68.

The name Granby also comes from Great Britain, one of the original references was for the "Marquis of Granby," John Manners. A Member of Parliament from 1754 until his death in 1770, he also was a popular army officer and hero of the Seven-Year War 1756-1763, obtaining the rank of Lieutenant General. In 1766, he was named British Commander-in-Chief of the Army. John Manners once had his hat and wig shot off during a cavalry charge, thus leading to the British expression, "to go baldheaded at something." He had his office attacked by the pseudonymous political writer "Junius." The Marquis of Granby resigned most of his offices and died in debt.

Curiously, Granby Hillyer had an uncle and a brother named Junius.
