The first settlers in Granby realized the sunny days and cool nights were perfect for growing one crop in particular, lettuce. Lettuce farming boomed in the 1920's and a new industry was born. Granby had become an important railway center as tracks were laid over the Divide at Rollins Pass,giving the Moffat Railroad access to Salt Lake City.

Granby produced some of the best-known lettuce in America. There are even tales that New York's Waldorf-Astoria Hotel bragged of their “Granby Lettuce” on the menu. Then a blight settled into the soil, probably brought in by the wooden crates used for shipping, and the lettuce business was ruined. Since then, ranching has replaced agriculture as Granby's major industry.

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.  

As fast as settlers arrived in the county, conflicts arose over water use.  George T. Bell, an early rancher on the Blue River in the 1890's, had water rights coming out of Deep Creek, Spring Creek, and Soda and Iron Springs.  Daughter Maud Bell had married James Mugrage and when her father died in 1925, she and James stayed on the ranch of about 800 acres, to operate it.  She reported years later that when Noonen, a large rancher also on the Blue, built his ditch, he took much of the Bell water and used it for his own benefit.  Many years later, Maud discovered that although her father was long dead, those early water rights still belonged to the Bells, not the Noonens. 

Another family, that of George Henricks, settled far up the Troublesome Valley, about 1900, in what was truly an inaccessible spot.  What possessed him to pick such a remote area for his ranch?  Because when he and his wife Aurille lived in Nebraska and tried to make a living on their farm, farmers upstream stole their water to the point that they couldn't keep their crops alive.  Aurille actually had to use the same batch of water for two or three purposes!  As water fights escalated, George vowed to find a place where nobody could be above him and his water source. Rancher Will Call took him far up the Troublesome valley to a large meadow, reachable only by foot or horseback.  Life wasn't easy, for George and Aurille had to do everything from scratch, and they lived in a cabin with a dirt floor for many years.  But nobody took his water! 

Even more recently there was a case on Crooked Creek, where a ranching family that owned quite a good spring and used it to water their hay, discovered that a new neighbor was diverting the water from the spring over onto his own land, to water his own hay!  The rancher protested and diverted the water back where it belonged.  The newcomer turned around and stole it again.  This situation went on for many years without good satisfaction.

The Kirtz Ditch development on the Troublesome began about 1890.  In 1911, an Elias T. Copelin homesteaded land, later adjacent to the Alexander and George Murray Baker ranches.  One day Copelin and Murray Baker, one of the brothers, got into an argument over water rights in the Kirtz Ditch, each accusing the other of stealing his water.  Murray, who was a little guy with a fierce temper, picked up a shovel and gave Copelin a mighty whack with it.  Copelin fell to the ground but after a bit picked himself up, climbed on his horse, and headed toward his home.  However, the blow must have damaged his brain because he was found the next day, dead on the ground at his own gate

High on Meadow Creek, in the early 1900's, lumber activity began in the area later known as Sawmill Meadow.  About 1910, the Western Land and Flume Co. put in a little dam near what is now the trailhead to Columbine Lake.  The resulting lake, today filled with water lilies, was used as a holding pond for logs that would be moved by flume to the main mill downstream in Tabernash.  This lumber company sold to Western Box & Lumber Company in 1912.  Business flourished.  There was even a short railroad going into the woods, with the tracks made of logs about 6" to 8" in diameter.  Prospects looked good.  However, from the beginning water rights were an issue. Some people say it was Nathan Hurd who broke the company.  Western Box had lost some of its water to the Strawberry Ditch (going to Granby) in 1914.  More trouble was looming.  Hurd wanted to keep the water from the little reservoir for the ranchers and lettuce farmers below.  The timber folks wanted to use the water during the summer months to keep the flume going.  Nobody was willing to give up anything, so in 1915, the big mill closed.   Still, efforts continued.

Then in 1919, the planing mill at Tabernash burned.  In the early twenties, further contention led to the withholding of more water from the lumber companies who wanted permission to ditch Trail Creek water across into Meadow Creek, replacing water taken higher up for the flume and Strawberry Ditch.  This would have been quite easy because, about seven miles out of Tabernash is a nearly flat saddle that exists between the two creeks.   Nevertheless the Hurds wouldn't hear of it.

Then one Henry Jarvis showed up on the scene.  He was known to all the timber men.  In 1923, Jarvis, using a box of TNT, "blew the dam" of the irrigation reservoir at Western Box.  People suspected that he did it for T.S. Huston, one of the big lumber powers of the area.  The feeling was that "if the lumbermen couldn't have the water, neither could the ranchers and the Granby farmers."  In any case, that basically was the end of Western Box Company. 

The mountains of Grand County may not boast any of the famous “fourteeners“ (14,000 feet and above), but Middle Park is defined by some of the most majestic ranges in the state. These include parts of the Front Range, Gore Range, Rabbit Ears Range, and the Williams Fork Mountains.

The only range Grand County can call entirely it's own is the Never Summer Range. It's highest point is Mount Richthofen (12,940 feet). Other major peaks include: Mount Howard (12,810 feet), Mount Cirrus (12,797 feet), Mount Nimbus (12,706 feet), and Nokhu Crags (12,485 feet). The name Never Summer is translated from the Arapahoe name, Ni-chebe-chii, which means “the place of No Never Summer“. The cloud names of Cirrus and Nimbus, and Stratus and Cumulus were the idea of James Grafton Rogers, a founder of the Colorado Mountain Club.

The Never Summer Range stretches for ten miles from Cameron Pass to Bowen Mountain. This range is darker and harder due the tremendous heat produced when the peaks were a localized center of volcanic activity.
