The principal population centers in the Fraser River Valley are Winter Park, Fraser and Tabernash.  When the early stage coaches came over Berthoud pass into the Fraser Valley, the most popular stop was at the Cozens Ranch, which now houses a historical museum in Winter Park. The valley is now bisected by U.S. Highway 40, which was designated the "Victory Highway" in 1931.  The new route of the highway leads through the main streets in both Fraser and Tabernash and the backdoors of some business became front doors because of the new highway alignment.   

Tabernash was the name given to a railroad siding, named for the Ute leader who was killed during a confrontation with local ranchers.  The town became a key station on the railroad line, and included a roundhouse, and a supply of helper engines for the steep climb over Rollins Pass.  When the Moffatt Tunnel was opened in 1928, the railroad no longer needed service there and the town lost its' main economic support.

George Easton founded the town site of Fraser in 1905.  The rest of the country became familiar with Fraser when the winter temperatures were often the lowest recorded in the U.S. and Fraser was know by the nickname "Icebox of the Nation".   Lumbering was one of the prime industries in the region until World War II.  During the war, the military built a Prisoner of War camp at Fraser to help lumber for the mills in the area.

The current area of Winter Park has had many names over the years.  First it was called simply "Old Town" or "Vasquez", named after the fur trader Louis Vasquez.  "Woodspur" or "Woodstock" referred to Billy Wood's lumber mill in the area, which furnished ties for the railroad while it was being built over Rollins Pass. During the construction of the Moffatt Tunnel, the name "West Portal" came into usage.  Rail workers also called the community "Little Chicago" as it was as it was a favorite gambling, saloon, and brothel site.  As tourists began to arrive it was known as "Idlewild" and also "Hideaway Park".  Finally, the name "Winter Park" was settled upon to correspond with the adjacent ski area of the same name.

The area population declined from 1232 people in the 1920's to only 373 people by 1930.  The Great Depression ended the construction boom and the price of beef became too low for ranches to turn a profit.  However, since that time, the area has thrived, mostly based on a tourism economy.  The valley's main source of income is now recreation and second home construction. 

George Henry Church and his brother John had a substantial ranch in Jefferson Country, prior to Colorado Statehood.  When the Timber and Stone Act of 1878 was passed, it permitted the purchase of land unfit for agriculture for $2.50 an acre.  Thus the Church brothers obtained land in Middle Park for summer grazing.  They would move their cattle into the Park by driving them over the Rollins Pass.   The area they used is just west of the town of Fraser and became known as Church Park.

In 1910, the Church Ditch was created to divert water across the Continental Divide for irrigation.  The remains of this early trans-mountain project can still be seen today at mile marker 241.5 on U.S. Highway 40.

In Yorkshire, England on October 15^th 1831, a clergyman and the daughter of a clergyman gave birth to small, sickly girl who would grow up to be one of the most well known travel writers of her time, an exceptional accomplishment in an era when women rarely ventured far from home unescorted. In 1850, after a childhood full of ailments, Isabella had an only partially successful operation to remove a tumor from her spine. Following the surgery, Isabella suffered greatly from depression and insomnia; it was then that her doctor recommended that she travel.  Isabella's father, becoming increasingly worried about his daughter, gave her a hundred pounds and sent her off to see the world.

Ms. Bird traveled throughout the world including Canada, Hawaii, Australia, China, Tibet and Morocco.  She came to Colorado right after the territory had officially been become a state. Isabella loved it in the mountains, so much so that she wrote many letters home to her sister which eventually came to become her third and most famous book, A Lady's Life in the Rocky Mountains. In this document, Isabella wrote of her adoration of the area saying, "I have found a dream of beauty at which one might look all one's life and sigh."

Upon her arrival to Colorado, she traveled into the mountains west of Estes Park. She wrote about adventures and challenges and of her romance with Jim Nugent, or "Rocky Mountain Jim" a one eyed outlaw with an attraction to violence and poetry. He was shot and killed a year after Isabella left Colorado.

Throughout the letters, Isabella mentions the wonderful sights of the lands she explored near current day Grand County.  In one of her letters, Isabella wrote of the time she rode a horse through a blizzard with her eyes frozen shut.  She found herself in another adventure when she was snowed in a cabin with two young men for several months.

Isabella grew eventually grew homesick and headed back to Edinburgh Scotland where she married a doctor. After five years of marriage, her husband died and Isabella returned to travelling. When Isabella returned to Edinburgh in 1904, she grew very ill and died while planning another trip to China.

The span crossing the Colorado River on State Highway 9 southeast of Kremmling is known as the Kimball Bridge.  It honors the memory of William H. Kimball who carried the mail over Berthoud Pass from Empire to Hot Sulphur Springs by foot, winter and summer.  Kimball was born in Maine and accepted the Middle Park mail contract in 1875.  Although reportedly nearly blind, Kimball traveled on snowshoes all winter carrying a backpack of mail weighing 70-105 pounds, day and night, at least once a week.

In  1884, Kimball established a flat bottom ferry over the Colorado River near the spot where the bridge now stands.  Before that time, no wagons could cross at that area.  With the addition of the ferry, load of game meat and fish could be taken up the Blue River to be traded for much needed staples. 

Kimball never married and lived at a nearby ranch until his death in 1909.
