Overview

Medicine Bow Mountains locator mapLocator Map

Located in north-central Colorado and southern Wyoming, the Medicine Bow Range stretches for a hundred miles from Cameron Pass in the south, to Elk Mountain in the north.  

Looking north into the Looking north at the southern end of the range

High elevations, peaks and lakes dominate the southern and northern reaches of the range, with lower, forested ridges being the mainstay in between. On the western fringes of the central portion of the range, the North Platte River cuts a deep, narrow, canyon over 20 miles long.The Colorado portion of the Medicine Bow is held between the Laramie River Valley on the east, and the high mountain valley or park known as North Park, on the west. In Wyoming, the range widens and is bordered by the Laramie Plains to the east and the North Platte River Valley to the west.

Using the 300+ ft of prominence rule, the range features 18 peaks over 11,000 feet and includes 9 over 12,000 feet, with 12,951 ft. Clark Peak being the highest. Climbing oportunities are concentrated in the southern and northern ends of the range.In Colorado, the range lies within Roosevelt NF and the Colorado State Forest (CSF), with a few small pieces tucked into Routt NF. Medicine Bow NF encompasses nearly all of the range in Wyoming. The crest of the range serves as the border of Larimer and Jackson Counties in Colorado.For descriptive purposes, the range can be divided into three sections:The north-south oriented, Alpine portion that is found in the south, the lower elevation timbered ridges and canyons in the middle, and the broad, high elevations of the Snowy Range in the north.

The Medicine Bow 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. Glaciation During the Pleistocene era, two Glacial Advances occurred in the Medicine Bow Range: the Bull Lake and the Pinedale. The Bull Lake event took place from 50,000 to 125,000 years ago, the Pinedale, 7,600 to 29,000 years ago. These were periods of extensive glaciation, with the Bull Lake glaciation being the most extensive.More recently, three smaller advances known as the: Triple Lakes, Audubon and Arapaho Peak made their mark on the range. The last of the three is commonly referred to as “The Little Ice Age”, and took place from the 14th to the mid-19th centuries. While no active glaciers are found in the Range today, numerous “permanent” snowfields exist in the southern and northern reaches. Unique Features There are two active Rock Glaciers located on the eastern slopes of South Rawah Peak.Two sets of Cold Weather Sand Dunes are located at the western foot of the range: The East Sand Dunes and the North Sand Dunes. Cold climate dunes contain sedimentary structures unique to moist, cold-climate dunes unlike the dunes of Great Sand Dunes NP. Like Great Sand Dunes NP, these dunes were formed when westerly, sand-bearing winds slowed and deposited their load on the western flanks of the range.The East Sand Dunes Natural Area contain the only undisturbed, cold-climated dunes in Colorado. The area is mostly within the boundries of the Colorado State Forest but is only accessable from the east. The North Sand Dunes, on the other hand are very accessible and open to recreational use by OHV’s and accordingly, not deemed a natural area. The North Dunes are currently managed by the BLM as The North Sand Hills SRMA

From south to north, the southern section of the range encompasses the area from Highway 14 to the northern edge of the Rawah Wilderness, a distance of 25 miles. From east to west, it ranges from the Laramie River Valley to North Park, varying from 9 to 15 miles wide. High alpine peaks, glacial cirques and pristine lakes are the rule in this southern portion of the Medicine Bow Range.

“Rawah” is a native american word meaning “wild place”. The Colorado State Forest State Park The Colorado State Forest was officially established on December 2, 1938, with President Franklin Roosevelt's issuance of a patent to the state of Colorado for 70,980 acres. It is administered by the Colorado Division of Parks.The majority of this side of the range lies at a lower elevation than the east side. The steep western flanks of the range in the State Forest are home to three small glacial cirques.

Forested ridges, punctuated by small and medium sized creeks, run from the northern edge of the Rawah Wilderness to Wyoming Highway 130, on the south side of the Snowy Range, a distance of some 37 miles. On the western edge of the range, the North Platte River’s Northgate Canyon provides a wild, remote river canyon. Elevations range from about 7,400 in the canyon bottom to 10,700 at the extreme southern and northern fringes of this section. Motorized recreation is the rule in all but the wilderness areas of this central portion of the range thanks to a myriad of forest roads.

Platte River Wilderness Created in 1984, this area encompasses 23,492 acres along the North Platte River in Northgate Canyon. Average elevation is 7,700 feet. Most of the wilderness lies in Wyoming (22,749 acres) with a small portion in Colorado (743 acres), where North Gate Canyon begins. The canyon is popular with white-water enthusiasts and anglers.The Platte River Trail offers some hiking oportunities in the canyon. Because of the narrow canyon and high river flows, late summer is often the best time to hike the canyon. The Douglas Creek Trail follows it’s namesake creek for 9.5 miles with a trailhead at either end.

This portion lies mainly in the Snowy Range and is dominated by Medicine Bow Peak, Browns Peak and Elk Mountain. Medicine Bow and Brown’s peak’s seperate ridges, measuring 4.5 and 3 miles, respectively, provide a spectacular backdrop to the area’s numerous lakes and large snowfields. Though the Snowy Range is not designated as wilderness, motorized travel has been limited since the 60's. Perhaps because of the rocky nature of the trails in the upper reaches, horseback travelers are not evident.

SummerThe Laramie River Road usually opens sometime in May. Depending on snowpack levels, trails leading into the southern parts of the range can be snow covered until early July.   Most roads in the CSF are open year-round, though access to some trailheads may be limited until early June.

The Snowy Range Road usually opens on Memorial Day Weekend. Some trailheads can be inaccessible by vehicle into early July. Trails in the higher elevations can be snow covered well into July, depending on snowpack levels.  The Laramie River Rd and Snowy Range Rd are open until snow closes them in the fall, usually around October or November.

WinterDue to the winter closure of the Laramie River Road, non-motorized access is limited to the extreme southern portion of the Range via Colorado Hwy 14.

On the western side, some access is available through the CSF.

Wyoming Highway 230, which is open year round, provides a narrow corridor of access to the central parts of the range though it is primarily used by snowmobiles.Further north, Highway 130 is closed in winter and access is from the end of the closure on the east and west sides of the range. This area also is primarily used by snowmobilers.

 

History

Prior to the arrival of Europeans, various Native American tribes ventured into the range at certain times of the 

Snowy Range SunsetSnowy Range Sunset

year to hunt and gather lodge poles. From the north and east, Northern Arapaho and Cheyenne, Oglala Sioux and Eastern Shoshone all frequented the valleys adjacent to the range. From the west came the White River Utes. Meetings between the Utes and the eastern plains tribes 

The Gap TrailHiking the Gap Trail along South Gap Lake

were not cordial and in effect, the range served as a no-mans land between mountain and plains tribes.The name Medicine Bow conjours up images of the old west and, rightly so. 

South Gap LakeSouth Gap Lake

The origin of the name comes from a merging of terms that early settlers associated with the range. The word “bow” refers to the local native’s preference for a particular variety of mountain mahogany found in the lower valleys of the range which they used to make bows of exceptional quality. The word “medicine” was associated with tribal gatherings, or powwows, that were held annually in the mountains. The tribes made their bows and held ceremonial powwows to heal the sick and rid the tribes of disease. The term “powwow” translated into “making medicine” to the settlers and over time, the two words were combined into Medicine Bow. In the early 1800’s, trappers began to penetrate the mountains and valleys of the Medicine Bow. One in particular left his name on the area. French trapper, Jacque La Ramie ventured into the valley of the river that would later bear his name to build a cabin and trap. He traveled alone to the fringes of the Medicine Bow Mountains in the Spring of 1820 and was never seen again. Rumor at the time suggested he was killed by natives, his cabin burned. A few years later, in 1834, Kit Carson spent a summer trapping near the headwaters of the Laramie River with three companions. Shortly before the group was to join up with Jim Bridger and head to the annual rendezvous on the Green River, Carson had an encounter with two huge grizzlies while hunting on the eastern slopes of the range. He managed to survive by climbing a stout aspen.The advance of the Union Pacific Railroad in 1867, across southern Wyoming brought in a new group of white men to the range-Loggers. Railroad lumber contractors operated camps in the mountains to supply railroad ties for the transcontinental railroad. The loggers, known as tie hacks, cut hundreds of thousands of lodgepole pine trees, which they hand-hewed and then floated down the Cache La Poudre and Laramie Rivers.A little piece of Tie Hack HistoryOn the eastern slopes of the central portion of the range was found a logging camp called Old Roach, which operated in the 1920's and 30's.Logging also took place on the western side of the range, though it wasn't all about railroad ties. In the Colorado State Forest logging activity peaked in the middle of the 20th century. The focal point for that activity, the Bockman Lumber Camp, grew to become Colorado's largest. See State Forest History for more detail.Most of the mining activity occurred in the northern section of the range. The town of Centennial on the eastern slopes of the Snowy Range, was a focal point for mining activity. Many mines were located high in the range, just west of Medicine Bow Peak in an area known as Gold Hill. Like a lot of mining in the west, the boom was followed by a bust, though there are still some active mines today. Water was the next resource to bring attention to the Medicine Bow. By the late 1800s river flows to the dry eastern plains of Colorado were already allocated which spurred speculators to seek new sources in nearby drainages. The Laramie River Valley on the eastern flanks of today’s Rawah Wilderness was one such source. A grand plan involving miles of ditches and a tunnel through the mountains to bring water from the Laramie to the Cache La Poudre was born. The plan didn’t live up to it’s potential when the United States Supreme Court ruled in Wyoming’s favor in 1922. Some of the ditches and the tunnel are still in use today though they don’t carry as much water as the original investors had hoped. With the publication of the world's first “western” novel, Owen Wister’s “The Virginian” in 1902, the name Medicine Bow became known world wide. Wister set his novel in the northern foothills of the range, near the town of Medicine Bow.

 

Wildlife

Mule Deer Mule Deer along the Sand Lake Road

Moose, elk, mule deer, bighorn sheep, mountain lion, black bear, coyote, bobcat, marmot, pika, beaver and fox are currently found in the range. Fish of the Medicine BowBefore the arrival of the white man to the region, the waters of the Medicine Bow Range contained no trout. Stocking, which began in the late 1800s, introduced several species of trout, two species of char and the Montana grayling.

In recent years some of the introduced species have been removed from the lakes in the southern reaches of the range in favor of the greenback trout, which is the “native trout” of the Colorado Front Range. Along with the greenbacks, anglers in the Rawah Wilderness may find: rainbow, mackinaw (lake trout) and brook trout.  In the Colorado State Forest, brook trout, cutthroat trout, brown trout and rainbow trout are present. Golden trout and grayling which were once present in Kelly Lake are gone in favor of the “non-native” native, greenback trout. The greenback has also been stocked in the CSF’s 2 other high lakes-Clear Lake and Ruby Jewel Lake. 

The Laramie River contains brook trout in the upper reaches with brown trout dominating the lower stretches.

Rainbow and brown trout are the most common trout found in the North Platte River.

The small creeks in the central part of the range are primarily populated with small brook trout.

In the Snowy Range, a similar variety of introduced salmonids can be found, though brook trout seem to dominate.
