Grand County was established in 1874 by the Territory of Colorado, thus becoming a county two years before Colorado became a state. It was named for the Grand River, the name by which the Colorado River was known at that time. The headwaters of the today’s Colorado River are in Grand County. The county was formed from a portion of Summit County but acquired its current boundaries in 1877, when part of the Grand County was used to create Routt County. The county seat is Hot Sulphur Springs. The area of 1,854 square miles consists of meadows, river valleys and mountains.

Colorow was a Ute Chieftain who was known for profound stubbornness and bitter resentment of the white man's intrusion into the Ute hunting grounds.  

Indian Agent Meeker had ruled that that the Utes must depend on the United States government for food supplies, rather than their traditional hunting. These supplies were sometimes held up for delivery and upon their eventual arrival,contaminated. Colorow thought the white settlers of Middle Park (near Granby) were killing too many of the game animals that had been critical in feeding the Ute people.  

So in the fall of 1878, Colorow started a brush fire high in the Medicine Bow range, planning to drive the deer, elk, and buffalo west to the Ute reservation.  But the winds took an unexpected shift, driving the wild game northward and away from Ute territory.  

The fire drove out the last of the buffalo ever to be seen in the Middle Park region again and it took many years for the forests and ranges to recover from the devastation.

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.

The town of Winter Park was first settled in 1923 and incorporated in 1978. It came into existence as a construction camp during the building of the Moffat Tunnel. The west portal is located here, hence the original name of West Portal.

As early as 1929 hearty winter sports enthusiasts were getting off the regularly scheduled trains there to ski the trails that were being developed. Regular weekend service on a special ski train began in January 1938. That same year, the U.S. Forest Service gave permission to the City and County of Denver to develop land near West Portal for winter sports, constructing ski-tows and trails. Winter Park ski area was formally opened in 1940.

With the consent of postal authorities, West Portal’s name was changed to Winter Park to publicize the ski area.  Benjamin F. Stapleton, the mayor of Denver at the time, championed the cause of the name change to help publicize the winter sports of the area. The town has now grown into a classic resort town and the ski area management has been recently turned over to the Intrawest Corporation by the City and County of Denver.
