Rocky Mountain National Park Centennial Celebration

Discover the Park...Go Beyond the Asphalt


CMC members played a significant role in 1915 in the designation of RMNP as a national park. The Department of Interior would not provide a map to Congress of the area to be designated without having named peaks on the map. CMC members traveled to the Arapaho Indian reservation in Wyoming and arranged for two Arapaho elders and an interpreter to join a horse expedition (the Toll Expedition 1914) in the Estes Valley. The group then set out in the park on horseback and returned with the initial peaks named by the Arapahoe natives. Because of CMC’s unique involvement 100 years ago, we are participating in RMNP’s Centennial.

One of the founders of RMNP, James Grafton Rogers, began lobbying for the Estes Valley to be designated as a national park in 1907. He became the first President of CMC in 1912. Two years later, in an effort to comply with requirements to have peaks named on a map of the proposed RMNP, two adventurous young women, Harriet Vaille and Edna Hendrie - both CMC members - traveled to the Wyoming reservation and returned with two Arapaho elders and an interpreter.  These Arapaho men joined the July 1914 Toll Expedition in the Estes Valley.  Returning two weeks later, the Arapaho elders had named more than 24 peaks which allowed the first map of Estes Valley with named peaks to be submitted to Congress. RMNP was designated as a national park in 1915. Today there are over 125 recognized named peaks in RMNP.

CMC is celebrating the RMNP Centennial by  offering member-led climbs of 100 of the 125 named peaks, hike packages totally 100 miles in the Park, and wildflower hikes in the summer of 2015.

Peak original names included:  Specimen Mountain (12,489’) was originally known as Mountain Smokes; Longs Peak (14,255’) and Mount Meeker (13,911’) were originally called “Two Guides” by the Arapaho. Mount Baker (12,397’) was originally called “Where the Sparrow Hawk’s Young Hang."

CMC members may register on for RMNP climbs/hikes in July 2014 and wildflower trips starting in the Spring of 2015. Contact the Year of the Mountaineer RMNP Centennial Committee at
