Summit County Colorado 150
In 2026, Colorado marks 150 years of statehood, and the Summit Historical Society is celebrating with a yearlong series of history-focused publications, programs, and events that are educational, engaging, and accessible.
This milestone year connects to key moments in our shared past:
- 1776 – The signing of the Declaration of Independence, marking the nation’s 250th anniversary
- 1861 – Formation of the Colorado Territory, with Summit County among its original 17 counties
- 1876 – Colorado’s admission to the Union on August 1 as the 38th state, earning the name The Centennial State
Our 50 + 50 + 50 = 150 initiative highlights Summit County people and their contributions across three 50-year time periods, 1876–1926, 1926–1976, and 1976–2026, with one individual featured each week from each era. We will also periodically highlight individuals from before Colorado became a state in 1876.
Each month will have a theme, such as skiing, starting in January.
Beginning January 5, join us here, on Facebook, and through our weekly newsletter, Happenings, and return often as the Summit Historical Society celebrates 150 years of Colorado statehood and the people who made a difference.
Please consider supporting the preservation of Summit’s past by making a donation today.

Colorado celebrated it’s centennial and the landscape shifted to year round outdoor activities from cross country skiing to mountain biking and hiking. Highway system improved access to Summit County as population increased with first and second home owners and increased tourism.
January - Skiing
Today, Summit County is famous for its abundant “white gold” and world-class ski resorts. Summit County skiing began in the 19th century, when mining communities used skis for travel, mail delivery, recreation and sport competition.
After World War II, as mining waned, improved transportation and growing recreational interest spurred ski-area development, shaping its economy, culture, and establishing it as a premier U.S. skiing destination.
The County’s first ski area was Chalk Mountain Ski Area, open from 1934–1962. Arapahoe Basin Ski Area opened in 1946, followed by Breckenridge Ski Resort in 1961, Keystone Resort in 1970, and Copper Mountain Resort in 1972.
