Granby was settled in 1904 and incorporated the next year. The town was created along the railroad line being built by Denver, Northwestern & Pacific, and was a connection with the stage route to Grand Lake. The Granby site was also chosen because of the dry ground and and good view of the surrounding mountains.

The town was named in appreciation of the services of Denver attorney Granby Hillyer, who worked to lay out the town site. Its central location makes it a natural trade center for east Grand County. Specialty truck farming, principally lettuce, became a major crop for Granby. At the peak of the market, the Waldorf Astoria hotel in New York City proudly advertised Granby Head Lettuce on its menus. Later, after WW II, Granby was called the “Dude Ranch Capital of the World.” Today the town offers a mix of recreational amenities and residential charm.

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.

The prospect of discovering a remnant from a 10,000-year-old stone age society that inhabited Colorado's Middle Park so long ago seemed remote at best - while the suggestion that a prized Folsom point could somehow materialize before our very eyes appeared all but impossible.  For one thing, it was the last day of excavating for the summer at the Barger Gulch archaeological site and the ten member scientific team would soon be packing up and heading back to their ivory towers at the University of Wyoming and the University of Arizona.

Barger Gulch is a desolate spot that the federal Bureau of Land Management (BLM) oversees. It is hard, parched dirt dabbled with sagebrush as far as your eyes can see across the flat valley - a haven for all manner of bugs and other forms of native wildlife. In winter, the place turns to the opposite extreme as temperatures plunge to minus 40-degrees and howling winds whip up ghostly images of snow that swirl eerily across the land. This is Middle Park, a high mountain basin with roughly the same geo-political boundaries as Grand County. It encompasses some 1,100 square miles of unforgiving territory flanked on three sides by the formidable wall of the Continental Divide and its terrain soars high over the Great Plains into the thin, alpine air up to altitudes of 13,000 feet above sea level. What would induce these primitive Americans to trek all the way up here without so much as horses for transportation? How would they have survived the brutal winters with only primitive tools and clothing?  And why in the world would they ever want to settle in such a barren, god-forsaken place as Barger Gulch? 

This site could well prove to be one of the most significant archaeological discoveries of its kind in North America, according to BLM officials who oversee the project here. In just three years of work in a relatively small excavation area, investigators unearthed more than 18,000 artifacts - a staggering number ten times that discovered at typical Folsom sites. And this is only one of four sites in the same vicinity.  In addition to Barger Gulch and Upper Twin Mountain, discoveries include the Jerry Craig and Yarmony Pit House sites. Most of these were occupied by peoples described by archaeologists as Paleo-Indians, a catchall term for ancient humans that inhabited North America; Yarmony Pit House post dated Paleo-Indians by about 3,000 years.

But long before Paleo-Indians ever set foot on the Continent, Middle Park was a prehistoric menagerie; 20-million years ago, it was the stomping grounds for prehistoric rhinoceros, three-toed horses, camels, giant beavers, and even small horses. Creatures known as oreodonts also romped across the mountainous terrain. These vegetarians, ranging in size from small dogs to large pigs, fed on grasses and green, leafy plants. In fact, the skull of one of these animals was discovered recently in the vicinity of Barger Gulch. These long extinct, hoofed animals resembled sheep, but were actually closer to camels, and were common in the western U.S. This latest discovery is remarkably well preserved; while the bones have turned to stone, the smooth, hard enamel that encased the animal's teeth is still intact. 

Humans arrived in North America much later - about 12,000 years ago - as the last Ice Age of the Pleistocene Epoch made its exit. These first Americans crossed a land bridge from Siberia to Alaska and began populating the entire Continent; experts believe it is possible they also arrived on boats following the Continental Shelf into North America. Folsom people are best known as nomadic, big game hunters who chiseled out their spear points and finished them off with a distinctive, artistic flourish - a unique groove, or flute, that runs lengthwise along the face that has become the symbol of this Paleo-Indian culture. They honed the tips of these primitive weapons surprisingly sharp for killing frenzies that were necessarily up close and personal: they herded their prey into traps before launching their spears - and archaeologists suspect there was just such a bison ambush site near Barger Gulch. The quarry just over the rise is a gold mine of raw materials, including fine-grained Kremmling chert and abundant Windy Ridge quartzite, which provided a never-ending supply of top grade stone. "It makes sense," explains Todd Surovell. "You would want to camp where you could get as many raw materials as possible within a short distance. That's where you're going to park yourself for awhile."

The bulk of these tools originated with local material, but investigators have found some 200  "exotic" items noticeably out of place at Barger Gulch. One is a distinctive piece of yellow, petrified wood that came from 93 miles away as the crow flies, near the town of Castle Rock on the Colorado plains. Another is a large biface that was brought up from the Arkansas Valley, some 60 miles south. "They worked on it up here in one place and turned it into two, maybe three projectile points," notes Surovell. "One of them broke during manufacture and we have two pieces that fit exactly together."

Fitting these and thousands of other pieces together is what archaeologists do when they get back to the lab. The process begins on site where investigators photograph each find and record its exact location within the excavation block. This gives the team a visual reference to help recognize activity patterns - a way to connect the dots of Folsom society.  But the specks come to an abrupt stop, as if they suddenly run into a solid wall. "If we could figure out that this represented the wall of a structure, that would be really special," he explains. "Nobody's even been able to do that before in a site of this age in North America." Just then, a graduate student pops his head inside the door. "You want to be a camera man?" he asks Surrovell. "What do you got?" "A Folsom point," he replies with a broad grin. We rush over to the site where Waguespack has dug a narrow shaft down the north wall of the excavation pit and hit pay dirt - a Folsom point that remains half buried in the stratum of rich soil.

The span crossing the Colorado River on State Highway 9 southeast of Kremmling is known as the Kimball Bridge.  It honors the memory of William H. Kimball who carried the mail over Berthoud Pass from Empire to Hot Sulphur Springs by foot, winter and summer.  Kimball was born in Maine and accepted the Middle Park mail contract in 1875.  Although reportedly nearly blind, Kimball traveled on snowshoes all winter carrying a backpack of mail weighing 70-105 pounds, day and night, at least once a week.

In  1884, Kimball established a flat bottom ferry over the Colorado River near the spot where the bridge now stands.  Before that time, no wagons could cross at that area.  With the addition of the ferry, load of game meat and fish could be taken up the Blue River to be traded for much needed staples. 

Kimball never married and lived at a nearby ranch until his death in 1909.
