Onahu Creek was called Fish Creek and is a tributary of the North Fork of the Colorado River. The name refers to one of the Indian race horses who came up to a campfire to warm himself, and the name means “warms himself“.  The horse ultimately died on Fish Creek and gave his name to the waterway.

Once upon a time on the land that lies beneath Lake Granby and Shadow Mountain Lake there were ranches, pastures and an almost forgotten town, Monarch.  It is a story that goes back 100 years to the Summer of 1905, and the arrival of train service in Middle Park and promoters who were "honest men, but too visionary and lacking in experience", according to Frank H. Wolcott, a brother of one of the founders.

The Monarch Consolidated Gold and Copper Mining and Smelting Company owned the King and Queen copper mines on Arapahoe Range above the South Fork of the Colorado River.  They felt their assays indicated ore worthy of a mill and arranged to haul in the heavy machinery and proceeded to build a town with cottages, a small hotel, stores, a bowling alley, theater and dance hall.  By 1907 Monarch had a school and post office.  However, records indicate only about $150 worth of copper per year was ever produced.    

Soon the promoters realized a sawmill was needed to provide both timber and cash to support the mine operation. A dam was built creating Monarch Lake at the junction of Arapahoe Creek and the South Fork of the Colorado, and a canal was built to float logs cut near Strawberry Lake to Monarch Lake.  A stern wheel steamer bunted rafts of logs into flumes and canals towards the sawmill downstream in Monarch.

In the spring of 1906, Monarch management obtained a charter to build the Rocky Mountain Railway, a standard gauge, for lumber and passengers, from the Moffat tracks in Granby to Grand Lake, with a spur over an unspecified pass to Walden, in North Park.  The track was laid following the river from Granby to the sawmill, by Japanese and eastern European laborers.  Ranchers along the route, excepting Fred and Frank Selak, quietly granted rights-of way. The only rolling stock owned by the railroad was a small, ancient locomotive and a caboose.  The night before Thanksgiving 1906 the first train rolled into Monarch, and the rails never extended any farther.  There was daily service, and local ranchers could flag a ride or have their packages dropped off.  There were no cattle guards, so the fireman would step off the locomotive, open a ranch gate, and close the gate and hop back on after the train passed through. 

During the winter of 1905-06 a box factory was started. It operated briefly before it was destroyed by fire in the fall of 1908.  The fire forced the mill and railroad into receivership.  Visitors, particularly former stockholders, helped themselves to equipment and entire buildings, but Monarch's core was preserved and developed by Harry L. Dierks of Kansas City into KaRose.  This summer resort was named in honor of Dierks' daughter Katharine Rose.  Other Monarch buildings went to neighboring dude ranches and the bowling alley went to Granby.  

To hold the railroad right-of-way, Ernest Behr restored the locomotive in 1912 to carry parties of fishermen along the river from one pool to another.  Ed McDonald, a dude rancher, ran a Cadillac touring car on flanged wheels on the rails to carry mail, supplies, and passengers to the valley ranches.  Just before World War I the engine and rails were sold for scrap. 

Frank H. Wolcott wrote, "In September 1954 my wife and I drove over the site to discover any signs of Monarch or the railroad...It gave us a queer feeling to realize that substantial things like railroads and buildings that we helped build have vanished.  Was it all a dream?"

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.     

In 1900, while visiting in Washington, D.C., Chauncey Thomas, a nephew of William and Elizabeth Byers, wrote ‘Snow Story, or Why the Hot Sulphur Mail was Late’.  When the great British author, Rudyard Kipling, read the piece, he pronounced it the ‘best short story by an American’.

The opening paragraph of the ‘Snow Story’ reads as follows:  ‘Berthoud Pass is a mighty pass.  It is the crest of a solid wave of granite two miles high, just at timberline. Berthoud is a vertebra in the backbone of the continent.  It is the gigantic aerial gateway to Middle Park, Colorado - - a park one-fifth as large as all England.  The mail for this empire is carried by one man, my friend Mason.’   The story goes on to describe Mason’s winter trip over Berthoud Pass into Middle Park where he encountered extreme winter blizzard conditions, an avalanche and Salarado.

Chauncey Thomas, a native son of Colorado Pioneers, was born in Denver in 1872 and died there in 1941.  At the age of three, Chauncey suffered his first loss.  ‘The light went out of my left eye forever.  A pair of scissors did it’, he said.  At age nine he received his first weapon, a .22 caliber revolver, and promptly shot himself in the foot.  No matter.  Forever after, firearms fascinated him.

He attended Gilpin and East Denver High School where he was a military cadet, but except for military drill and mathematics, school interested him very little.  After graduation and college attendance at Golden, Colorado and Lake Forest, Illinois, he found his way to New York City. Here, he worked as an editor for well-known magazines - McClure’s, Muncey Publications, and Outdoor Life (among others) and hobnobbed with the likes of Ida B. Tarbell, S. S. McClure, Jack London and Frederic Remington.  He returned to his home town and occupied himself more and more with Denver’s historic past.  

On the night of September 23, 1941, in his garret room at 1340 Grant Street, he took up a scrap of paper and wrote: ‘stroke--agony’.The next morning a neighbor found him, pistol in hand, dead.  Two years later, at Berthoud Pass on a mountain that bore his name, Chauncey Thomas was honored.  Dr. LeRoy Hafen the Colorado State Historical Society’s historian and the Colorado Historical Society dedicated a monument to him on which was inscribed, Chauncey Thomas: Sage of the Rockies.
