Many noted fur trappers and traders are reported to have been familiar with the headwaters of the Grand (Colorado) River as early as the 1820s. Among them were Thomas Fitzpatrick, Jim Beckwurth, Christopher “Kit “Carson, Henry Fraeb and Peter Sarpy. Louis Vasquez built a trading fort on the South Platte River and ventured into what is now Grand County, where a pass east of Berthoud Pass is named for him.

His partner, Andrew Sublette, also came across the Divide to trade in Grand County, as well as Ceran St. Vrain, whose fort was near modern Platteville. 26 year old Tom Smith was with a group of trappers who entered the northern part of Grand County in 1827, where they were attacked by either Ute or Arapahoe Indians. Tom was hit in the leg by an arrow, splitting the bone and creating a life threatening infection. Amputation was needed but none of the party had the nerve to perform the operation. So Tom took a butcher knife and amputated his own leg. As “Pegleg Smith” Tom later became noted as one of the greatest horse thieves in the West, but was never prosecuted.

The beaver trade was essentially over by the 1840s as silk replaced beaver pelt as the stylish material for top hats. In 1842, famed traveler Rufus Sage came over Muddy Pass into Middle Park, but recorded almost no hunting activity there. On the other hand …fishing was great! His party caught over 50 pounds of trout in one morning. Noted mountain man Jim Bridger and another guide, Joseph Chatillon, let the infamous Sir George Gore on an extravagant hunting expedition in Middle Park. Despite the senseless slaughter of thousands of game animals, Gore has been immortalized with a mountain range, canyon and pass named for him.

One of the earliest of the mountain men to discover what was to become Grand County arrived in the Fraser Valley as early as 1860, soon after gold was discovered in Colorado. Charley Utter, known as “Colorado Charley”, was considered the prototype of rough trappers and traders. He was unique, though, in that he insisted on taking a bath every day, whether in the hot springs or beneath frigid waterfalls. In 1864, Charley was one of the first to make use of Berthoud Pass driving cattle that he raised at Troublesome Creek. His home was host to various adventurers who came to explore the prospects of Middle Park. He would eventually work with the famous Buffalo Bill Cody, appearing in “Wild West” shows.

When Kentuckian Beverly D. William spent some time in Grand County, he realized the Grand River was originally named the Colorado. As a Washington delegate from the newly organized “Jefferson Territory” (as this area was known at the time), he was instrumental in getting the named changed to the “Colorado Territory”, although the river was called Grand River until 1921.

Before there were any people anywhere, the Creator, "Sinawaf", cut sticks and placed them in a large sack.  After many days, this aroused the curiosity of the coyote.  When Sinewaf was away, the coyote could no longer control himself and opened the sack.

Out came many people who scattered in all directions.  Each spoke a difference language from the others.  When Sinewaf returned, there were only a few people remaining in the sack.  He was furious with the coyote, as he had planned to distribute the people equally in various parts of the land.  As there could now be no such equity, there would be wars among the different people, who would fight for the best locations.

Of the small group left in the sack, Sinawaf called them Ute or Nuche, which meant "the people".  They would be a very brave and strong tribe.

Construction on the railroad line from Denver to Grand County began in July 1902.

The project, called the Moffat road (officially the Denver, Northwestern & Pacific), was the seemingly impossible dream of David H. Moffat, who spent much of his personal fortune building the tracks over the Continental Divide.

The rails pushed higher and higher up the mountains until they reached a station named Corona, meaning the crown of the continent.

Corona was the highest point in the world with a standard gauge railroad and the journey from Denver in the winter was perilous at best.

Huge snowplows were required on either side of the Divide to keep the tracks clear.

Eventually, in the late 1920s, a tunnel was dug through the range, eliminating 22.84 miles of track and the breathtaking journey over Rollins Pass.

The railroad reached Granby and Hot Sulphur Springs in 1905 and Kremmling in 1906, and played a significant role in building the population of Grand County.

In 1900 the total resident population of Grand County was only 741, but grew to 1,862 in 1910.

Monarch, now a picturesque lake for meandering around on a pleasant summer day, was once a bustling town, the home of the Monarch Consolidated Gold and Copper Mining and Smelting Company, and the rail head of the Rocky Mountain Railroad.  The life of this little company town and railroad was very short lived and now nearly forgotten. 

Boulder business men T.S. Waltemeyer, and Frank and Charles A. Wolcott heard about traces of gold, silver, and mostly copper at the junction of the Arapahoe Creek and the South Fork of the Colorado River.  In 1905 they established the Monarch Consolidated Gold and Copper Mining and Smelting Company and built their company on the assumption that a major belt of minerals extended east through the Continental Divide.  The Monarch Company consisted of several subsidiary companies including lumber companies, an "investment" company, an exploration company, and a development company.  The main objective of the company was to mine metal ores, but supplement it with timber and build a railway to benefit the whole corporation. 

The company had 1740 acres of placer and lode claims; the main mines were the Copper King, Copper Queen, Omaha, Ella C., and High Lonesome. The Monarch Company shipped heavy machinery by flatbed cars to Granby on the new Moffat Road.  They then put an ad in the paper asking for bids to haul heavy machinery 16 miles from Granby to Monarch.  The machinery included "5 boilers (eight and a quarter tons each), one engine (over eleven tons), one flywheel (6 tons), other machinery (from 1 to 5 tons), a carload of nails, and several hundred pounds of miscellaneous supplies."  The task of hauling the heavy equipment was made especially difficult by mud-holes and bridges not made for heavy loads.  Denver hauling companies refused to take on the job and one Swedish logging company from Wyoming abandoned the challenge after the first wagonload stuck in a mud-hole.

Finally Dick McQueary agreed to move the machinery.  To accomplish the job, McQueary purchased several hundred feet of hardwood planks in Denver, 3 inch thick, sixteen inches wide and twelve feet long.  Accompanying the heavy pieces up the mountain was a "4 horse team hauling hardwood plank, a 4 horse team pulling six inch pine poles, 10 feet long, and a four horse team pulling two ton large nails".   The crew built temporary bridges across mud-holes by laying pine poles 3 feet apart with hardwood planks laid across the poles.  2 light loads were driven across to test bridge followed by the heavy load pulled by 12 head horses.  Finally the planks and poles were pulled up to be used at the next mud-hole.  The heavy machinery was hauled in 2 weeks.

Construction on the Rocky Mountain Railway, a standard-gauge line from Granby to Monarch, began in 1907.  The 16 mile line was completed by Thanksgiving.  There were hopes of someday extending the line to Grand Lake for resort passengers and eventually a line to Walden in North Park.  The Denver and Northwest Railroad Company helped survey the line by lending J.J. Argo's services.  Dick McQueary was once again brought in to grade the road bed between the Monarch mill and Granby.  Most of the workers on the railroad were Japanese, Bulgarian, Hungarian, and Austrian day laborers from an employment agency in Denver.  The laborers were paid $2 a day, (plus a fifteen cent fee for their interpreter).

Once the railway was completed and in operation it issued passenger tickets.  However, the company never published a schedule.  Neither did the company hire a full train crew to run their single locomotive.  To meet regulations for switching service on Moffat tracks in Granby, the Rocky Mountain Railroad took on board a couple of interested bystanders.  At gates crossing ranch properties fireman Leo Algier would simply jump off the train to open the gate and close it after the train had crossed through before hopping back on the train.  Ranching families on the line were allowed to catch rides on the train when it passed through or to request package drop-offs. 

The Monarch Company created Monarch Lake by damming the valley, at the junction of Arapahoe Creek and South fork of the Colorado River, for use with the saw mill and the box factory. A 2800 foot long chute carried tree trunks down the hillside to the lake where they hit the water and could bounce up to 50 ft high.  Then a stern-wheel steamer pushed logs into a system of canals and flumes that led down to the saw mill and box factory. 

The town of Monarch included employee housing, business offices, a post office, and an assembly hall.  Dick McQueary helped haul sawlogs to mill and haul materials for building employee housing in Monarch.  Grand County's first hydro-electric generator was in Monarch.  The waterworks system was created by piping water from the falls at Mad Creek and had pressure up to 300 lbs per inch. 

Even thought the mining company never produced more than $150 a year, the owners continued to promote the business to stockholders and they were able to keep the business running by through their enthusiasm for the project.  During the summer, stockholders were invited to visit Monarch, tour the site, and hear lectures on the operation.  The tour often included a visit to a spruce tree named "Monarch" that was seven feet in diameter.  So, while business might not have been booming, enthusiasm and interest from stockholders was.  

The last piece of Monarch to be constructed was the box factory in 1907.  Unfortunately the factory only operated for 2 or 3 months before it suffered a fire and was totally destroyed.  Robert Black in Island in the Rockies stated that the questionable promotions of Monarch would have been forgiven if the box factory had developed into a solid operation. 

Soon after the fire, a disagreement between management and labor resulted in the entire work force being fired.  For several months the Rocky Mountain Railroad operated the train with one man who acted as engineer, fireman, brakeman and conductor. The company hired Dick McQueary as general manager until fall the fall of 1907 when stockholders discovered the true state of the company and declared bankruptcy.   Stockholders and the community were convinced that the whole company had been created as stock-selling scheme.

Although the Monarch Company and the Rocky Mountain Railroad were no longer in business, the railway continued to be used for a number of years.  For example, Ed McDonald, dude rancher, put a Cadillac touring car on flanged iron wheels to carry mail, supplies, and guests to his ranch.  The center of town was preserved and developed by the Dierks as a summer resort called Ka Rose, after Katherine Rose Dierks, after the owner's daughter.   In 1912 the rail line was used for transporting fisherman along the river by Ernest F. Behr, a former Colorado and Southern engineman.  Finally, in 1918 the rails were sold to a junk dealer in Denver to satisfy the World War I need for scrap metal. 

Currently, the town, mill site, and box factory lay under the waters of Lake Granby and are inaccessible, except in years of draught.  However, there are a couple of remaining pieces at Monarch Lake that are still visible.  On the south side of the lake, near the water's edge, is a boiler that was used to yard logs into a chute and shoots the logs into a holding pond.  Also, the flume still runs down the hillside into the lake.  The trail around Monarch Lake takes hikers directly under the flume.
