Grand Lake was established in 1879 and incorporated in 1944. It is named for the largest natural body of water in Colorado.

In 1867, when only a few people resided near the lake, Major John Wesley Powell (the man whose group first rafted the Grand Canyon) came to explore the possibility of floating down the Grand (now Colorado) River. That summer, Powell, local resident Jack Sumner, and William Byers, founder of the Rocky Mountain News, made the first recorded ascent of Longs Peak from Grand Lake.

In the early 1900’s a Yacht Club was formed by enthusiasts who were attracted by the demands of attentive seamanship the lake demanded. In 1912, Sir Thomas Lipton contributed an impressive cup to be presented annually to the winner of the annual August Regatta. This event still draws skilled sailors to the challenging competition. 

The town was founded during a very brief mining boom, but because of it's natural beauty, tourism has long been the sustaining feature of it's economy.

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.

Washington Irving wrote "There is, perhaps, no class of men on the face of the Earth who lead a life of more continued exertion, peril and excitement, and who are more enamored of their occupations, than the free trappers of the West".

The diet of the mountain men at times consisted of nothing more than meat. When possible. wild plants and berries supplemented needed vitamins.  Pemmican, a meat pounded with fruits and dried in flakes, was convenient to carry and lasted a long time. Mountain men made boudins, sausage made from the intestines of newly killed animals.  These sausages were packed full of undigested grasses which probably protected the mountain men from the illness of scurvy.  The mountain men also chewed on leaves and wild grasses to supplement their vitamin needs.  Potatoes soaked in vinegar supplied further balance to the diet.  Jams and orange marmalade were highly valued whenever they could be obtained. Bread consisted almost entirely of hardtack, a touch cracker usually unsalted, which would not spoil and sturdy enough not to crumble.

Beaver tail soup was considered a delicacy by most mountain men.  Another treat was called "French dumplings", made by mincing buffalo hump with marrow, rolling it into balls, and covering with flour dough and boiled.  Coffee was popular, but limited for transport.  Tea from China came in solid blocks which could be shaved off as needed. 

Normally, mountain men could not carry whiskey on the move but at rendezvous or during visits to forts, they were known as fabulous drinkers.  The most common intoxicant in those days was "Taos Lightening", a strong whiskey manufactured by Simeon Truly of Taos New Mexico.  Various writers have portrayed these men as brutes who lived from one drunken episode to the next, but the facts, and common sense contradict that image.  They could not achieve much in either trapping or trading if they did not stay focused on their outdoor skills and survival. 

Smoking pipes was a luxury, mostly at nights as only a limited amount of tobacco could be obtained.  The mountain men would stretch their tobacco supplies by mixing it with kinnick-kinnick and other plants.

While many traders and trappers dressed in buckskin shirts and trousers, wool garments were even more common and needed to be shrunk to fit.  Probably every mountain man carried what was called a "possibilities bag" that contained personal items such as a pipe, tobacco, soap, needles, and small keepsakes such as mouth-harps.

Before the Sharps "Big 50" rifle was invented, it was necessary to carry a waterproof powder horn and a bag of rifle balls weighing fifty to a pound.  A good knife was essential.  The most sought after of these was the Bowie Knife, invented by Rezin Bowie, but made famous by his brother Jim, who was adept at its use.  Jim was one of the heros killed at the Battle of the Alamo in Texas.

Some mountain men simply loved the lifestyle and had no reason to return to their original homes.  Some had wives back in St. Louis and made an annual trek there every year.  Others had Indian wives or female companions.  Some men claimed to have a wife in every tribe they visited.  Divorce within many tribes was often simple, a matter of putting one's belongings outside the lodge.

As journeys by foot or horse were lonely, mountain men were known to play their mouth harps or sing songs along the trail.  The use of profanity was common, except in the presence of white ladies.  One writer claimed the Indians called white men "Godams" because that swear word was used so frequently by the mountain men, ranch hands and mule skinners.
