Berthoud Pass was named for Captain Edward L. Berthoud, who completed the first survey of  this saddle in the main Divide in the spring of 1861.

Berthoud’s expedition of eight people, including Jim Bridger, crossed the Continental Divide at the 11,315 foot summit and established a relatively easy way to get into Middle Park from the east. Berthoud also served as chief engineer on the Colorado Central Railroad.

It is surprising that this famous pass had played no previous role in the history of the region. Even Jim Bridger, who knew the country well, did not learn of its existence until the survey. For reasons of their own, Indians had chosen to go over the divide at higher levels further to the north. One explanation may be that the pass is not evident from most locations on either side of the Continental Divide.

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.

Washington Irving wrote "There is, perhaps, no class of men on the face of the Earth who lead a life of more continued exertion, peril and excitement, and who are more enamored of their occupations, than the free trappers of the West".

The diet of the mountain men at times consisted of nothing more than meat. When possible. wild plants and berries supplemented needed vitamins.  Pemmican, a meat pounded with fruits and dried in flakes, was convenient to carry and lasted a long time. Mountain men made boudins, sausage made from the intestines of newly killed animals.  These sausages were packed full of undigested grasses which probably protected the mountain men from the illness of scurvy.  The mountain men also chewed on leaves and wild grasses to supplement their vitamin needs.  Potatoes soaked in vinegar supplied further balance to the diet.  Jams and orange marmalade were highly valued whenever they could be obtained. Bread consisted almost entirely of hardtack, a touch cracker usually unsalted, which would not spoil and sturdy enough not to crumble.

Beaver tail soup was considered a delicacy by most mountain men.  Another treat was called "French dumplings", made by mincing buffalo hump with marrow, rolling it into balls, and covering with flour dough and boiled.  Coffee was popular, but limited for transport.  Tea from China came in solid blocks which could be shaved off as needed. 

Normally, mountain men could not carry whiskey on the move but at rendezvous or during visits to forts, they were known as fabulous drinkers.  The most common intoxicant in those days was "Taos Lightening", a strong whiskey manufactured by Simeon Truly of Taos New Mexico.  Various writers have portrayed these men as brutes who lived from one drunken episode to the next, but the facts, and common sense contradict that image.  They could not achieve much in either trapping or trading if they did not stay focused on their outdoor skills and survival. 

Smoking pipes was a luxury, mostly at nights as only a limited amount of tobacco could be obtained.  The mountain men would stretch their tobacco supplies by mixing it with kinnick-kinnick and other plants.

While many traders and trappers dressed in buckskin shirts and trousers, wool garments were even more common and needed to be shrunk to fit.  Probably every mountain man carried what was called a "possibilities bag" that contained personal items such as a pipe, tobacco, soap, needles, and small keepsakes such as mouth-harps.

Before the Sharps "Big 50" rifle was invented, it was necessary to carry a waterproof powder horn and a bag of rifle balls weighing fifty to a pound.  A good knife was essential.  The most sought after of these was the Bowie Knife, invented by Rezin Bowie, but made famous by his brother Jim, who was adept at its use.  Jim was one of the heros killed at the Battle of the Alamo in Texas.

Some mountain men simply loved the lifestyle and had no reason to return to their original homes.  Some had wives back in St. Louis and made an annual trek there every year.  Others had Indian wives or female companions.  Some men claimed to have a wife in every tribe they visited.  Divorce within many tribes was often simple, a matter of putting one's belongings outside the lodge.

As journeys by foot or horse were lonely, mountain men were known to play their mouth harps or sing songs along the trail.  The use of profanity was common, except in the presence of white ladies.  One writer claimed the Indians called white men "Godams" because that swear word was used so frequently by the mountain men, ranch hands and mule skinners.     

The Muddy Creek Valley, on the western edge of Grand County, has a rich history, mostly based on ranching. It became something of a multi-cultural region, attracting French, Greek, Belgian, British, Dutch, Austrian, Swiss, German and Jewish settlers.  There were also dozens of homesteading families that came from eastern Colorado and Mid-West America.

The known prehistory of the Muddy Creek area extends back 10,000 years at a kill site for bison on Twin Peaks, which separates the Muddy from the Troublesome Creek drainages. 

Among the early settlers in the region were the Ed Pinney family who has a ranch near the summit of Gore Pass.  As the boundary between Grand and Routt County was not well defined, Ed paid his taxes to whichever county had the lowest rate in any given year.  After the railroad arrived at Kremmling, a stage coach route to Topanos, west of Gore Pass, was started.  At first the Pinney Ranch was designated a lunch stop, and then an overnight stop.  In 1906, the Pinneys' built a big house that could accommodate up to 40 people, two to a room.

One of the many notable ranches was that of Fred and Myrtle DeBerard.  Their Park Ranch included 20,000 acres, and they ran over 1600 registered Herefords.  Fred was instrumental in the creation of four reservoirs in the region.

Another prominent early rancher was Frenchman Alfred Argualer, who first came to hunt the region but returned to establish the May-Be-So Ranch.  He continued developing properties from 1880 until 1911 when he sold his ranch on the Muddy to Nick "Turk" Constantine.

A significant rancher of the 20^th century was Walter "Wad" Hinnan, who served form 1966-7 as President of the Colorado Cattlemen's Association and as Director of the National Western Stock Show in Denver.  He was instrumental in breaking the barrier between cattlemen and sheep growers by showing that both enterprises could be complimentary and profitable.  Wad also represented Grand County in the Colorado Legislature from 1968 to 1982.

At one time in the early 1920's there was a sanatorium for World War I veterans who had been disabled by mustard gas.  The lower Muddy was the site of an ice house which supplied refrigeration for fruit shipments out of Grand Junction and Palisade, Colorado.  German prisoners of war were used to cut the ice during World War II.

A unique innovation resulted from the widespread ranching families.  In 1935, the schoolhouse was put on sled runners so that it could be taken to which ever ranch had the most children for that season.  It was moved in the winter as the school terms were held during the summer.  It was moved three times between 1931 and 1939 and was probably the only mobile schoolhouse of that era.
