Kremmling started as a general mechandise store, owned by Rudolph (or Kare) Kremmling, on the ranch of Dr. Harris, located on the north bank of the Muddy River. In 1888, John and Aaron Kinsey had part of their ranch platted, calling the site Kinsey City. Kremmling moved his store across the river from the new site and the town that subsequently developed became known as Kremmling. There was a post office established at Kremmling as early as 1885 and the town was incorporated in 1904. 

The Middle Park Fair was established here in 1912. Famous Western Novelist Zane Grey spent time in Kremmling and, as a result, wrote "Mysterious Rider" in which the area is shown as a classic Western setting.

During World War II the town was the location of a prisoner of war camp where German prisoners cut ice that was shipped by rail to other locations.

The local ranching industry, the presence of the railroad and its strategic location at the confluence of the Colorado River, the Blue River, and Muddy Creek made Kremmling a natural location for a town, which still retains the “Old West“ atmosphere.

The Grand Lake Library was originally sponsored by the Women's Club of Grand Lake.  In January of 1933, the club voted to sponsor a town library to collect sufficient number of books may be obtained to open the in October.  A newspaper article from December 13, 1933 stated:

"The Grand Lake Woman's Club is glad to announce that its free public library is now open to the public at the home of Mrs. Goldie Hawkins. Books may be exchanged every Thursday from 10 am to 5 pm. There are over 300 volumes of fiction and non-fiction for both adults and children. The Club is grateful to many of our citizens as well as to summer residents who have donated these books. It is by means of their generosity that our library is made possible at this time. Lumber for the shelves was donated by Henry Schnoor, and Preston Hawkins built the shelves without charge." Mary L. Cairns, Chairman Library Board.

The Juniper Women's Club, a junior club of the Grand Lake Women's Club first opened a library in January 1945. It started in a small room in the Community house used for town council meetings. The library was allowed to use the room rent free; however, the library was soon bursting out at the seams and unable to take book donations due to lack of space. When the town council and the firemen decided to build an addition on the firehouse in the winter of 1947, the Juniper Club sought and received permission to have an upstairs room of 16 ft. by 18 ft. for the library. There was a condition; the room was to be finished by the club. A contract was let for the complete finishing of the room with built in shelves on the east and west walls and a sub floor. A wiring contract was also let. To earn the money for the payment the club had bingo, potluck suppers, card parties and food in a basket.

Since January of 1945 836 books were added to the 900 books of the former library. In February of 1948 the books were all moved to the new library, by hand and through the snow, with the assistance of the club members' husbands. In the summer of 1948 these books were all classified according to the Dewey Decimal System by the club members. From the May 1948-May 1949 Juniper Club President's report:

• Our main project has been and will be our public library. We have approximately 2000 books which are mostly fiction. The first year fifty new books were purchased for $134. There were approximately 200 library cards purchased by our patrons.
• In May a benefit card party was held and $34 was cleared for the library. Two baskets of food were sent from member to member and $26.25 was raised this way.
• In July a silver teas was given at the library room. A lovely program of music, pictures of Hawaii, etc. was given. $50.75 was cleared from this tea for the library.
• During August the club women sold chances on a service for six, sterling silverware set. 330 chances were sold earning $229.73 for the running of the library.
• New Year's Eve, a dance was given and $29.83 was cleared for the library project.
• In addition to the 50 books purchased, an oil stove was purchased, curtains were made and the floors were refinished for the library by club members.

 From newspaper articles of 1949:
"The library boasts 1650 volumes, most of them good recent books, and it is open two afternoons a week in winter but three in summer with Mrs. Agnes Gingery as librarian. This year's project for the Juniper Club under the direction of Mrs. Grace Eslick, president, will be the landscaping of the area within the circle drive around the fire house in the Community House block. Last Sunday the first of a series of square dances was held at the Southway Lodge, with a good crowd attending. These dances are put on by the Juniper club and will be for the benefit of the Grand Lake library. They will be held every Sunday night and refreshments are served free. If you do not know how to square dance and would like to learn, we will be glad to teach you. The square dances at Southway's on Sunday evenings are proving very popular as well as lucrative for the library fund."

During the Christmas holidays the new floor was laid and new shelves were built. Materials and labor cost $150 of the club's square dance money. The club spent $650 on the library room. 116 books were added, 75 by donation and 41 were purchased.

The Juniper Club then started a beautification program in the area of the town square and around the fire house and library.

The Juniper Library at Grand Lake became a branch of the Grand County Library System in 1988. In May of 1995 the Juniper Library moved from the Fire Station to a location just off the town square.

With increased library use and development of computer information systems the need for a larger space was recognized and a new library was built adjacent to the Town Hall and dedicated in June of 2006. Serving local residents as well as guests to the community, Juniper Library’s diverse collection, beautiful space, and helpful librarians make it a center of the community.

"I shall never forget it as long as I live. Nor do I ever expect to experience anything comparable to it again. Civilization had found its way across the mountains into Middle Park," reflected Mrs. Josephine Button in 1955 on her 91^st birthday, as she recalled seeing smoke from the first Denver Northwestern and Pacific work-train on Rollins Pass, high above the Fraser Valley and Middle Park. Once those rails made it over the Continental Divide all the way to Hot Sulphur Springs, "changes came thick and fast." Many men, many dollars, many routes and many dreams tried to bring a railroad over the Continental Divide into Northwest Colorado, and the "Hill Route" over Rollins Pass that finally accomplished it a century ago has retained its allure ever since.

The Moffat Railroad built a cafeteria, telegraph station, living quarters for Moffat's "Hill Men" (as the railroad crews up there were known) and a fine hotel - all collectively called Corona Station. Soot-filled snow sheds protected over a mile of this windblown section of track. And where today silence is the most powerful sense, colorful locomotives pulled passenger and freight cars, filling the rare atmosphere with black smoke and mechanical clatter.

Decades of men's dreams lay behind the once massive snow shed that cut the bitter winds from the north and west, behind that fine hotel that offered some of the most spectacular scenery in America, behind the hopeful Town of Arrow nestled below tree-line ten or twelve miles west of Rollins Pass, and behind that first work-train that Josephine Button watched from her hay ranch along the Cottonwood Pass Wagon Road to Hot Sulphur Springs. Competent, often powerful, men in the 1860's through the 1890's filed surveys, graded road beds, and even began drilling before being stopped by severe storms that foiled the best laid plans or their inability to fund the ambitious projects.

Dreams to penetrate the high mountains along the Divide in central Colorado began when the Front Range was flooded with miners during the Gold Rush of 1859. Even before Colorado became a territory in 1861, Golden City, just west of Denver along Clear Creek, recognized its potential as a gateway to the rich mineral resources of mountain towns like Central City, Black Hawk, and Georgetown. Golden City's ambitions went beyond becoming a mountain transportation hub, believing that with the right incentives, enthusiasms, and leadership, its location supported a future as a national commerce center. 

Golden City certainly had men of vision, ambition, and wealth among its ranks. William Loveland and George Vest, both young and feverishly ambitious to see Golden City reach its potential, vigorously pursued their dreams for a powerful commercial center in Golden City. From Missouri River towns like Leavenworth in Eastern Kansas, leading town founders also recognized the benefits of linking their water and rail routes to the east with the resources of the west. Finally, as if destiny had demanded it, Edward L. Berthoud, a young civil engineer and surveyor with energy and ability, arrived in Golden City from Leavenworth in April of 1860 to unite the similar passions of leading citizens from both locations.

From 1861 until 1866, Berthoud, Loveland and Vest focused on bringing a direct transcontinental railroad route through Golden City. First, Edward Berthoud, along with Jim Bridger and a capable young cartographer named Redwood Fisher, blazed a trail across Berthoud Pass through Middle Park all the way to Salt Lake City. Returning to Golden City on May 28, 1861, Berthoud reported "a good wagon road could be ?quickly' built" from Denver to Salt Lake City over Berthoud Pass for about $100,000.00. According to the local hyperbole, a railroad would surely follow.

In spite of considerable enthusiasm, disappointment plagued early efforts to put a rail line over the mountains in Colorado Territory. In 1862, Territorial Governor John Evans sent the Surveyor General for Colorado and Territories along Berthoud's route and others to confirm or deny the potential of a railroad line. About the same time, the Union Pacific Railroad Company sent an independent reconnaissance to examine potential routes over the divide that included Berthoud and Boulder Passes (Boulder Pass became Rollins Pass in the early 1870's, when John Quincy Adams Rollins built a toll road over it, and then Corona Pass when the Railroad crossed it). Surveyor General Case and the UP agreed that neither route offered much hope for a standard gauge railroad. The dream of a transcontinental line over the Continental Divide through central Colorado seemed to die with the UP surveyor's words, "I learned enough to satisfy myself that no railroad would - at least in our day - cross the mountains south of the Cache la Poudre..." 

Multiple failed attempts to bring a rail line over the Divide through Middle Park during the following decades strengthened the UP's "death sentence." Against the odds, Berthoud and Loveland continued to solicit support for a railroad west over or through the Continental Divide, using improved surveys and maps to support their requests. In the 1880's, survey crews from a variety of railway incorporations were scattered over the high country on or near Rollins Pass. Over Berthoud, Rollins and other passes, they marked potential railroad lines with their wooden stakes. It was during this stretch of strenuous surveying activity that David Moffat, a highly successful Denver capitalist, got involved with an unsuccessful effort to bring through the mountains instead of over the top. 

 In the early 1880's, Mr. Moffat invested in the Denver, Utah and Pacific Railroad, which intended to tunnel through the mountains near Rollins Pass. Like the other efforts, though, the Denver, Utah and Pacific vanished in a few short years. Unlike many other lines that accomplished little more than surveys and maps, the DU&PRR completed significant grading and began tunneling before reaching the "end of its resources."

Money, power and success supported Moffat's dream to put Denver on a direct transcontinental railroad line. Doctor Robert C. Black, III, wrote that David Moffat's failed efforts in the early 1880's converted him to the idea that Denver needed to be on a direct transcontinental rail line. Moffat considered the route over Rollins Pass valuable enough to have surveying and grading crews working on it throughout the winter in 1902. The Denver Rocky Mountain News claimed that Moffat's route through Northwestern Colorado included "the largest strip of fertile land as yet undeveloped in the United States..." With his Denver, Northwestern and Pacific Railroad, David Moffat planned to make good his intentions to put Denver on direct transcontinental railroad line.

Moffat's original plan called for the "Hill Route" over Corona Pass ? the name changed from Rollins Pass in honor of Corona Station at the top ? to last for only a few short years. While the "temporary" route over the top generated resources by extracting the resources of Northwestern Colorado, a tunnel was to be bored through the Continental Divide. Even the wealth and power of Moffat, though, failed to adequately finance the tunnel before he died in 1911. The temporary line, therefore, lasted for nearly of a quarter century, from 1904 until 1928.

Its obstacles proved as enormous as the mountains it crossed. Work crews had to cease operations because of snow for most of April in 1920. The road was closed from late January until May in 1921. In December of 1924, engine number 210 busted "a main reservoir pipe," causing the train to fly down the hill out of control until it jumped the tracks and crashed into the valley below. Clearly, the Denver and Salt Lake Railroad, which took over Moffat's DNW&P after his death, needed a tunnel to replace the expensive effort over the "Devil's Backbone."

 As Denver and Salt Lake Locomotive Number 120 came through the tunnel in early 1928, it represented the culmination of a massive undertaking through wet, unstable rocks which required considerable engineering ingenuity and caused six deaths in a 1926 cave-in. It also took an enormous amount of coordination and effort to secure the necessary funding. Through local bond issues, private investors and other means, the project was completed. And through a connection at Dotsero, a railroad station less than 30 minutes west of Vail on I-70, freight and passengers could make a direct Pacific connection from Denver. Posthumously, David Moffat's dream became a reality.

For significant periods of time since the trains stopped operations over Rollins Pass in the late 1920's with the opening of the Moffat Tunnel, on-road vehicles crept along its relatively easy grades and wide curves from Rollinsville on the east slope to Winter Park on the west side of the Divide. Like now, the road ran through an area attractive to backcountry campers and sport enthusiasts. On September 1, 1956, local officials and private citizens met on Rollins Pass to celebrate a "joint state-federal-county project to convert the old D. & S. L. railroad right of way over Corona Pass into an access road for sportsmen." According to the Denver Post, the game and fish department's construction division reconstructed the road during the summer of 1955 for about $20,000. The following year, the road became a scenic route over the Continental Divide for family cars and jeep caravans alike. And after it was built, or at least reconstructed, they did come.
