The Territorial legislature defined the boundaries and county seats for the West Slope in 1861.  Geographic knowledge of the Colorado mountains was somewhat limited at that time.  North Park (a name now synonymous with Jackson County) was an Indian hunting ground and little was known about it.

A boom started with the discovery of gold and silver at Teller City in 1879.  North Park was considered to be part of Grand County, and now there was property to assess and tax.  The Grand County road tax in North Park for 1881 applied only to males between the ages of 21 and 45.  They had to either pay $3 in cash or do two day's work on the roads. John Mills, a Teller City resident who acted as an attorney for mine owners, served as a Grand County commissioner and was one of the commissioners killed in the July 4, 1883 gun battle at Grand Lake.

As ranches became established and more mineral deposits were discovered, the Larimer County commissioners began to speculate that the "Snowy Range" that defined the western boundary of Larimer County was the Park Range on the west side of North Park rather than the Medicine Bow Range.  This opinion soon degenerated into a dispute between Grand and Larimer counties, ultimately ending up in court. In 1886 the Colorado Supreme Court ruled that North Park was part of Larimer County.

A trip to the county seat in Fort Collins was a considerable undertaking.  If everything ran on schedule it was possible for travelers to leave Walden on the morning stage, catch a train from Laramie to Cheyenne, another train from Cheyenne to Greeley, still another from Greeley to Fort Collins, and arrive at the county seat before closing hours the following day.  The fares amounted to a significant expense.  It was probably more common for a North Parker to travel to Fort Collins in his wagon, take care of business, and come home with a wagonload of provisions.  The trip by wagon took three to four days each way.

As the population of North Park grew, so did the desire to split from Larimer County.  In 1908 the Loveland newspaper stated that Larimer County was too big and advocated a new county with Loveland as the county seat.  The Walden newspaper agreed that the county was too big but felt the wrong division line had been picked, pointing out that "A Loveland man can get to the county seat in three hours anytime, but it takes a North Park man three days most of the time."

Ranchers resisted early efforts to set off the area west of the Medicine Bow Range into a county of its own as they carried the largest part of the tax burden and felt their taxes would increase if a new county was established.  But by 1908 there was general agreement within the Park that it was time for court and administrative offices to be more conveniently located.

The total valuation assessed in 1908 of North Park property by Larimer County was $771,776, which generated $16,979 of revenue.  The salaries of some of the paid officers of the new county was estimated as follows:

     Assessor                                                    $800

     County School Superintendent                   $800

     Water Commissioner, 2 districts                $1000

     County Commissioners                             $1000

Even adding in salaries for the sheriff and county clerk it appeared quite likely that the new county could be operated efficiently without a tax increase and the proposal to create "North Park County" had nearly unanimous support from North Parkers.  The bill passed the legislature easily in April 1909, with a name change to Jackson, and was quickly signed into law on May 5 by Governor Shafroth.

While North Parkers were eager to sever their legal ties to Larimer County in 1909, they clearly weren't ready to give up the pleasures of offered by a nip of the bottle.  Like most frontier areas, North Park had a significant number of single men who liked to occasionally get together and enjoy a few drinks with their friends.  Walden was the center of socialization.  According to an 1899 newspaper article, Walden residents worried about the "toughs" who came to town to "drink barbed-wire bitters and then shoot up the place."

In addition, local married men sometimes frequented the bars when they could have been spending more time at home helping out with domestic chores.  As a result, a strong temperance movement soon divided the community.  One of the two local newspapers, the North Park Union, endorsed the temperance movement in early 1902 and soon found itself the target of a boycott by both advertisers and subscribers.  Although the editor declared it a "boycott of no great magnitude", the paper had a new owner/editor within a month.  The issue of whether Walden should be wet or dry was on the 1902 ballot.  By a very decisive majority, voters decided Walden would continue to be wet.

Just before the 1906 election, the Walden newspaper criticized the local Republican Party bosses for providing a lot of free whiskey in every North Park precinct on election day, and urged North Parkers not to sell their vote for a drink.  The temperance movement enjoyed its first victory when it combined forces with the local church and convinced the businessmen of Walden to close their stores on Sundays.  The closing did not stand in high favor with ranchers.  "When a man can't buy axle grease for his wagon when it runs dry and something else for himself when he runs dry, it is time to call a halt," they declared.  Quite a number of the ranchers started going through to Laramie for their provisions, and the Sunday closing rule was abandoned six weeks after it was implemented.

When news reached Walden in early 1909 that the bill creating Jackson County had cleared the legislature, the newspaper reported that the town was moved to the point of a merry celebration.  The brass band marched, guns were fired, and at daybreak "the women, as becomes their sex, were among the few who were sober."  A few weeks later news that the Governor had signed the bill was cause for another celebration.  The newspaper reported that, "the air about town clouded up and filled with burnt powder and raucous vocalizations.  The festivities continued in the evening with flying anvils propelled by stick powder . . ." The first hundred years of Jackson County had commenced.

One of the oldest brands in Colorado still in use by the same family is the Bar Double S brand of the Sheriff Ranch near Hot Sulphur Springs. The current owners of the ranch are John Brice and Ida Sheriff. In 1863, Matthew Sheriff of Keithsburg, Illinois came to Colorado to search for gold in the California Gulch, near where Leadville would be established. Mathew was dismayed by the gray mineral which consistently clogged the gold sluice, and gave up on his dreams of instant wealth to return to Illinois.

Many other miners also gave up mining for this reason, never realizing that the gray mineral was carbonite of lead, which was rich in silver. Mathew died in 1863 at the age of 40, leaving behind his wife Marietta and their 3 surviving sons, Burt, Glenn and Mark. In 1878, Marietta was inspired to return to Colorado in search of security and stability for her family. She spent some time in Leadville running a boarding house. Her sister was the wife of William Byers who was developing the Hot Sulphur Springs area so Marietta moved to the area to settle with her sons. In 1882 the family homesteaded three ranches of 160 acres each, proving them up and added a preemption right to another 160 acres.

Bert later moved to Denver and established a livery stable and Mark and his mother moved into Hot Sulphur Springs, while Glenn continued to work the ranch. Glenn married Alice Cleora Smith in 1886 and they had two surviving sons, Brice and Glenn Jr. Glenn Jr. was only 6 weeks old when his father died at the age of 33 of “brain fever” or diphtheria. Alice took the children back to her family in Iowa to raise them, but the boys returned to their Colorado ranch in 1910. Brice, who suffered from a back injury as a child, bought an abstract business in Hot Sulphur Springs and lived there with his mother for the rest of their lives.

Glenn Jr. continued to expand and develop the ranch and married Adaline Morgan in 1923. They had four children; Nona, John, Robert and Catherine. Glenn Jr. served Grand County as a Commissioner for 24 years and also as the County Assessor for 4 years. Glenn Jr.s, son John, took over the ranch and married Ida Marte in 1949. Ida’s family had homesteaded their own ranch near Cottonwood Pass. They have two children and continue to work the ranch to this day.

The principal population centers in the Fraser River Valley are Winter Park, Fraser and Tabernash.  When the early stage coaches came over Berthoud pass into the Fraser Valley, the most popular stop was at the Cozens Ranch, which now houses a historical museum in Winter Park. The valley is now bisected by U.S. Highway 40, which was designated the "Victory Highway" in 1931.  The new route of the highway leads through the main streets in both Fraser and Tabernash and the backdoors of some business became front doors because of the new highway alignment.   

Tabernash was the name given to a railroad siding, named for the Ute leader who was killed during a confrontation with local ranchers.  The town became a key station on the railroad line, and included a roundhouse, and a supply of helper engines for the steep climb over Rollins Pass.  When the Moffatt Tunnel was opened in 1928, the railroad no longer needed service there and the town lost its' main economic support.

George Easton founded the town site of Fraser in 1905.  The rest of the country became familiar with Fraser when the winter temperatures were often the lowest recorded in the U.S. and Fraser was know by the nickname "Icebox of the Nation".   Lumbering was one of the prime industries in the region until World War II.  During the war, the military built a Prisoner of War camp at Fraser to help lumber for the mills in the area.

The current area of Winter Park has had many names over the years.  First it was called simply "Old Town" or "Vasquez", named after the fur trader Louis Vasquez.  "Woodspur" or "Woodstock" referred to Billy Wood's lumber mill in the area, which furnished ties for the railroad while it was being built over Rollins Pass. During the construction of the Moffatt Tunnel, the name "West Portal" came into usage.  Rail workers also called the community "Little Chicago" as it was as it was a favorite gambling, saloon, and brothel site.  As tourists began to arrive it was known as "Idlewild" and also "Hideaway Park".  Finally, the name "Winter Park" was settled upon to correspond with the adjacent ski area of the same name.

The area population declined from 1232 people in the 1920's to only 373 people by 1930.  The Great Depression ended the construction boom and the price of beef became too low for ranches to turn a profit.  However, since that time, the area has thrived, mostly based on a tourism economy.  The valley's main source of income is now recreation and second home construction. 

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.
