We’re now in the final year of a decade, and it’s hard to believe that it has been nearly 20 years since the 20th century came to an end. Time sure has flown by! While the world has changed quite a bit over the last 10 years, it’s incredible to consider how much has changed over the last 100. This got us wondering just what Colorado looked like a century ago, so we turned to our friends at History Colorado and found these 20 stunning photos of the Centennial State during the 1910s.

1. Situated along Denver's popular Larimer Street, Star Grocery was once a popular spot to shop for fresh fruits, vegetables, and meat. (1910)

2. While most Colorado mines are now dried up and closed down, the mining industry was extremely important to the early growth and development of the Centennial State and drew countless settlers and families to the area. (1910)

The old Gold King Mine in Gladstone (pictured above) is notoriously known for leaking 3 million gallons of mine waste water and tailings into the nearby Animas River.

3. Located in Las Animas County is the unincorporated community of Hoehne, which was once home to this "Wholesale Flour & Feed" store. (1911)

4. Offices have certainly changed since the early 1910s! This photo was snapped in Gladstone, Colorado. (1911)

5. A beautifully colorized photo of a wildflower-filled Colorado landscape. (1912)

6. It’s hard to tell exactly which town this is, but it’s clear that skiing has ALWAYS been popular here in Colorado! (1912)

7. Members of the Colorado Mountain Club leaving Estes Park in a super cool old car. (1913)

8. The Colorado Mountain Club taking a break from hiking in Rocky Mountain National Park. (1913)

9. Men and women from the Ludlow Colony during a strike. (1914)

10. Tragically, the Ludlow strikes led to the Colorado Coalfield War, in which 19 men, women, and children were killed. (1914)

11. Pictured below is the John Bianchi General Store, which once operated in the unincorporated town of Sopris in Las Animas County. (1915)

13. He flies through the air with the greatest of ease; he's a daring young skier on the Howelsen Hill Ski Jump in Steamboat Springs! (1916)

15. This photo was captured inside the boiler room of the Gold Prince Mill in Gladstone. (1917)

16. This photo was captioned "Colorado Mountain Club field day game of tug-of-war." Does this club still exist? If so, how does one join?! (1917)

17. Is it just me or does the Broadmoor still look EXACTLY the same? (1918)

18. Cattle branding on the Gallatin Ranch. (1918)
