After 1879 there were no Native Americans in Grand County.

In the 1800, the leading cause of death in Grand County was accidents followed by pneumonia.

Between 1887 and 1902, Grand County had no divorces.

The total resident population of Grand County in 1900 was 741.  The average life expectancy was 47 years.

Winters in Grand County often were severe, but nothing as terrible as the winter of 1898-1899.  Warm weather preceded the storm which began on February 2nd.  Four feet of snow fell by that first evening and the residents did not see the sun for the rest of the month as the snow continued to fall.  The snow continued into March and April and while few residents died, but the loss of livestock was tremendous.

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.

After his discharge from the Union Army in 1865, a veteran who lost his right arm at the Battle of Shiloh, Tennessee as a commander of a field artillery battery, John Wesley Powell was appointed curator of the Illinois Natural History Society’s Museum located at Illinois State University-Normal. Later, he was a Professor of Natural Science at Illinois Wesleyan University-Bloomington. 

In the summer of 1867, Professor Powell and his wife Emma, brought five students of the two university’s and six educators at other Illinois schools to Colorado Territory. Two peaks over 14,000 feet were climbed. Pike’s Peak (Emma was the 4^thwoman to do so), and Mt. Lincoln. The expedition combined exploration and higher education of large scale student field trips was the first of its kind in American college history. 

In the autumn, the Powell’s visited the natural Middle Park hot springs (the heart of Hot Sulphur Springs) owned by William N. Byers editor of the Rocky Mountain News. The caretaker of the springs introduced himself as Jack Sumner, also a Union Army veteran, and Byers’ brother-in-law. Near the springs was the Grand River as the headwaters of the Colorado River were called. Around a campfire Powell and Sumner made plans for a Colorado River Exploring Expedition. Looming over this decision on the eastern horizon was Long’s Peak.  In November, Wes and Emma Powell departed for Illinois filled with fortitude to return to Colorado. 

John Wesley Powell sought financing for an 1868 expedition from the museum and university’s boards of education, being happy to oblige. However, his request to draw supplies from U.S. Army western warehouses took an Act of Congress to approve. The Smithsonian Institute donated scientific materials. The expeditions purpose was to stock the natural history museum with large collections of specimens representing different sciences and illustrating the resources of the country. Before leaving Illinois for Colorado, it was understood that the ascent of Long’s Peak would be attempted. 

At Chicago on June 29^th, a special Pullman car of the Chicago & Northwestern Railroad arrived with a banner lettered “Colorado Scientific Exploring Expedition”. At 3 p.m. Professor and Mrs. Powell, with 19 others were taken to Omaha, Nebraska traveling all night. In the morning they rode a Union Pacific train to Cheyenne, Wyoming. They were organized into messes of four and drew supplies from the army warehouse. Each man had to break his own bronco for the pack train ride to Denver. One man was bucked into a cactus. A Reverend was thrown with his foot hung in a stirrup. While being dragged he said, “take hold of her boy’s. Whoa!  Sweet little angel you.” They arrived and camped at Denver on July 14^th. Then proceeded to Empire where they were greeted by mountain man and guide Jack Sumner,  William Byers, and Ned Farrell.  

So much was untouched to be plucked in the names of anthropology to zoology. A week was spent on Berthoud Pass. One young scientist shot a jack rabbit thinking it an antelope. Jack Sumner was used to dudes. Finally, the expedition arrived at Mr. Byers’ resort where headquarters and the Reverend’s “Preaching Tent” was set up. Rest and relaxation were enjoyed by soaking in the hot springs. 

Professor Powell used his military rank Major. He never let the loss of his right arm hinder him. The Major took a trip to the Rabbit Ears and Gore Range where the highest peak is named Mt. Powell. When he returned the Major selected his student squad for the ascent of Long’s Peak. Chosen were L.W. Keplinger, and Sam Garman. One old mountaineer told the two that nothing could get them there that didn’t have wings. The idea of tenderfeet trying the ascent was ridiculous!

August 20^th-22^{nd -}The Major, his brother Walter Powell, Jack Sumner, William Byers, Ned Farrell, and the squad, departed headquarters mounted on horses, and one pack mule with 10 days rations. Each carried a pistol or rifle. The squad had weather equipment. They camped at Grand Lake. In the morning the party of seven rode up a steep rock ridge almost impassable by fallen timber. They corralled the equines at Mt. McHenry elevation 13,327 feet and camped for the night. At 7 a.m. the Major made bacon and biscuits. The men stuffed their pockets with a two day’s allotment. Leaving their firearms behind Sumner and Keplinger led the way to Wild Basin over tortuous terrain. All arrived exhausted at 2 p.m. except for Keplinger who volunteered to find a route to Long’s Peak. Keplinger went through the notch and was within 200 feet of the crown. Turning to enjoy the view he almost became an eternal resident of Estes Park. Nightfall was setting in and he had to return to Wild Basin. To his amazement Sumner was hollering and had lit beacon fires. At 10 p.m. Keplinger and Sumner were in camp. 

At 6 a.m. on August 23^rd, Keplinger led the way. Required of each was caution, coolness, and intense labor; life depending on the grasp of fingers in a crevice that would hardly admit them. Moving up in order were Keplinger, the Major, Sumner, Byers, and the others. Before 10 a.m. the entire party stood on Long’s Peak summit, elevation 14,255 feet. “Glory to God!” shouted the Major. For three hours they remained enjoying the spectacular views. North, south, east, and west. They counted 32 alpine lakes. An American flag was flown and left. A monument was built, and a baking soda can was used as a time capsule. Placed in the capsule were each member’s names, and the temperature. A biscuit was going into the capsule but the Major objected as he wanted fame as a mountain climber and not a biscuit maker. The capsule was sealed for the next climbers to find. Wine was sprinkled on the monument and disposed of in the usual manner. Two members abstained. 

The descent route went towards the branches of the St. Vrain River. Noticed on the snowbanks were two bears feasting on grasshoppers numbed by the cold. On the western branch of the St. Vrain the party was out of grub and they rested for the night. The men hiked to Mt. McHenry where a hearty breakfast was made. The two Powell’s, Sumner, Byers, and Farrell, returned to the springs on August 25^th. Keplinger and Garman remained to record high altitude weather. Submitting the first mountain climate observations to the Smithsonian Institute. 

The First Recorded Ascent of Long’s Peak (with a lengthy caption) was published in the Rocky Mountain News by William N. Byers on September 1, 1868. Proud of the fact, “that all were eminently successful and satisfied; the more so because the mountain had always before been pronounced inaccessible, and ours was the first party that had set foot on its summit.” 

The rounded mountain at the head of the East Inlet to Grand Lake has born many names-from Middle Mountain, to Mount Baldy, to Mount Westcott. It's official title, however, is Mount Craig. It's namesake is The Reverend William Bayard Craig, who came to the area in 1882, to be pastor of the Central Christian Church in Denver. He visited Grand Lake occasionally, and completed some real estate dealings there. The town of Craig also bears his name, due to the influence of his friend, David Moffat, of the Denver and Salt Lake Railroad.
