Under New Ownership
I adopted this Range after the page originator, Andy, became inactive. I hope to give the Range the more complete and informative page it deserves. Please let me know any thoughts and/or suggestions you might have regarding page renovations.
Located in Northern Central Colorado, the Mummy Range extends northward from Chapin Pass in Rocky Mountain National Park
(RMNP) approximately 20 miles to the Cache La Poudre River. The southern half of the range lies within RMNP while the northern half is contained within Roosevelt National Forest and the Comanche Peak Wilderness. Most climbing opportunities are found in the RMNP portion of the range where 15 summits exceed 12,000 ft.

Origin of the Name
From: Cache La Poudre: The Natural History of a Rocky Mountain River.
Major erosion from the Lawn Lake Flood. When 30 million cubic feet of water came downhill in a hurry!
The name “Mummy” seems singularly inappropriate for that imposing range, visible as it is for many miles to the east and to the north and to the south. Early visitors apparently saw a resemblance to a reclining Egyptian mummy. The Arapahoes called them nooku-bee3ei-no which translates to “White Owls”. It is not certain who first called them the Mummies - it may have been Albert Bierstadt, who visited the area in 1876.
Due to it’s relative remoteness and, for the most part, long approaches, the range sees fewer visitors than most areas of the Park. In contrast to RMNP as a whole, most access points, other than those in the extreme southern portion of the range, are somewhat far-flung and reachable only by lengthy drives on unpaved roads.
Winter access is good in RMNP with the exception of the Chapin Pass trailhead. In the northern part of the range, Winter access is limited due to seasonal road closures. See the trailhead list below for more detail.
Cache La Poudre River. This spot was featured in the opening scenes of Centennial with Pasquinel and McKeag crossing here on horseback.
On July 15, 1982 the Lawn Lake Dam collapsed, causing 30 million cubic feet of water to race down the Roaring River at a rate of up to 18,000cfs as it dropped 2,500 feet to Horseshoe Park below. From there, the flood waters continued down the Fall River, obliterating a small dam before the waters slammed into Estes Park. The alluvial fan created by the flood waters is plainly visible today. A hike up the Lawn Lake Trail still reveals the power of that flash flood of more than 30 years ago. Lawn Lake/Roaring River Flood
On June 3rd, 1944, a B-17 Bomber with a crew of 10 crashed high on north-facing slope in the northern reaches of the Mummy Range. Six crewmen survived the crash. The crash site
is accessible by trail.
The western, northern and north-eastern limits of the range are marked by Colorado’s only Designated Wild and Scenic River-The Cache La Poudre

The Mummy Range was formed during the Laramide orogeny, which began about 70 million years ago and lasted approximately 30 million years. Multiple faults in the area were thrust upward, creating the beginnings of the range. After a period of much volcanic activity, 25 to 40 million years ago, the range and surrounding areas were buried under a thick blanket of volcanic ash. Over the last 25 million years, the range continued to rise, reaching it’s current elevation in the last few million years. All the while, the power of erosion sculpted the canyons and valleys. Climate changes beginning 1.8 million years ago changed the engine of erosion from water to ice and the era of the glaciers began.
The range shows much evidence of glaciation in the past but only remnants of the great glaciers are left today. Rowe Glacier, between Hagues Peak and Rowe Peak and a few “permanent” ice/snowfields are all that remain.

As far as camping areas other than the backcountry sites, Aspen Glen CG
in RMNP is the closest. A number of private campgrounds and numerous other accommodations are available in Estes Park.
Northern Half-Roosevelt National Forest/Comanche Peak Wilderness
The northern part of the Mummy Range is located outside RMNP, except for the extreme southern portion. While there are many miles of trails to hike in the northern Mummies, climbing opportunities are limited and primarily located on or near the northern boundary of RMNP. Additionally, a few peaks over 11,000 are found to the north and northwest of Comanche Peak. Elevations range from 8,000 to 12,700 feet.
