The original Grand County contained North Park as well as Middle Park, and during the mining boom of the early 1880's there were several mining camps east of the modern town of Rand. It was several years after the mining boom northern area of Jackson County was created.

Teller City was founded in 1879 and named for Colorado's famous Senator Henry M. Teller, who later became U.S. Secretary of the Interior.  By 1882, the population of Teller City was about 1200.  It had a fine hotel with 40 rooms, a newspaper and two steam saw mills.  It was a lively Old West town with twenty seven saloons and a number of "houses of ill repute".

Some high quality ore assayed at Teller City was as much as $3000 a ton, but most of that soon ran out and by 1884, the high shipping costs to far away smelters dropped the price per ton dropped to $20. The best mine, Endomile, was three miles from town.

Crescent City, southwest of Teller City had an even more brief existence, but there was population enough for a U.S. Post Office in 1880. 

Rumors of valuable silver three miles sough of Teller City drew a number of prospectors to found the camp known as Tyner.  John Noble Tyner was the First Assistant Postmaster General of the United States and visited the mining camp so named in 1879.  He promised the miners a weekly mail delivery if at least 2 miners mined through the winter.  Tyner had been a special agent for the Post Office from 1861 thru 1868, at which time he was appointed to serve in an open seat in the U.S. House of Representatives for Indiana.  He ran for election win the appointed term ended and was elected and continued to be reelected and serve as a Representative until 1875 when President Grant appointed him Second Assistant Postmaster General.  Grant would later appoint him to the "big job" of Postmaster General in 1876. 

Tyner worked to elect Rutherford B. Hayes in 1876 and after Hayes was elected and took office in March of 1877, Hayes appointed a new Postmaster General, but gave the second spot, First Assistant to the Postmaster General to Tyner.  Historians suggest that Tyner's demotion angered him to the point that he allowed wide spread corruption in the day to day operation of the Postal Service which was his responsibility to over see. He resigned in 1881 under great public pressure from what became known as the "Star Route Fraud scandal".  He would remain a political figure  being appointed  various positions  with the U. S. Postal Service until shortly before his death in 1904.  Although indited three times for corruption in his Post Office management, he was never convicted.  The "Star Route Fraud scandal", may have local implications.  It had to do with over charging and providing needless postal routes, roads and post offices and kick backs to politicians from contractors .

Howard Henry Yust was the sixth child of Charley and Mary Yust, born April 18, 1891 on their homestead by the Blue River six miles south of Kremmling. At age eleven, Henry worked as a teamster. He and his brother Bill rode broncs at early Middle Park Fairs. He homesteaded part of the ranch then grew potatoes Wynn Howe sold at his Troublesome store. Henry and his brother Ed raised lettuce in 1924-5 where Mesa, Arizona is now.

Winters, Henry and Ed broke horses. Daily they rode five miles through deep snow. The first day one brother led the unbroken horse ridden by the other brother. The next day, the two rode their two horses together, but separately to feed the Yust family cow herd at the mouth of Gore Canyon. Loose hay pitched onto team pulled sleds was pitched off in meadows.

In the summer of 1931 Jack Shiltz approached Henry while he and Ed were building the first water carrying flume/suspension bridge over the Blue River and asked if he would work for Middle Park Auto in Granby as a mechanic. Henry asked Ed if he wanted the ranch. Ed said yes, so Henry left. Later, Henry operated Standard stations in Kremmling, first the current Kremmling town hall, second now O'Aces Liquor. After he leased the second station to Dolye Likely, Henry operated a rock shop where he sold jewelry he made.

July 7, 1943 Henry married Mary Anna Ostergaard. They raised Mary's nieces Willa Jo and Donna Dee Ostergaard. On his last visit to Kremmling August 30, 1980 Henry showed Jim Yust the location of Elliott's cabin on Elliott Creek three miles south of Kremmling. Elliott squatted on land now owned by Blue Valley Ranch when he was killed by Indians taking revenge for the killing of Chief Tabernash. This band went on west to participate in the Meeker Massacre (1879). Henry died Election Day November 4, 1980 in Northglenn, Colorado.

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.

The town of Winter Park was first settled in 1923 and incorporated in 1978. It came into existence as a construction camp during the building of the Moffat Tunnel. The west portal is located here, hence the original name of West Portal.

As early as 1929 hearty winter sports enthusiasts were getting off the regularly scheduled trains there to ski the trails that were being developed. Regular weekend service on a special ski train began in January 1938. That same year, the U.S. Forest Service gave permission to the City and County of Denver to develop land near West Portal for winter sports, constructing ski-tows and trails. Winter Park ski area was formally opened in 1940.

With the consent of postal authorities, West Portal’s name was changed to Winter Park to publicize the ski area.  Benjamin F. Stapleton, the mayor of Denver at the time, championed the cause of the name change to help publicize the winter sports of the area. The town has now grown into a classic resort town and the ski area management has been recently turned over to the Intrawest Corporation by the City and County of Denver.
