Overview

"Ptarmigan Flat Top”, a.k.a Peak 12,008, is the quintessential mountain in the Flat Tops. It is steep on most sides, but almost flat on top with vast nearly flat or rolling areas of tundra. It is the 5th highest ranked peak in the Flat Tops and also the highest ranked peak in the Flat Tops without a name.

Because the summit was covered in ptarmigans on our ascent on August 18 2012, I propose the name “Ptarmigan Flat Top” for this peak. The approach to the peak is quite scenic and this is one of the easier of the 12,000+ foot peaks in the Flat Tops to climb. The basin to the southeast of the peak holds many popular lakes (the Mandall Lakes), but very few people make the extra effort to climb this peak.

The peak certainly is rich in wildlife. In addition to ptarmigans, we counted 21 marmots and many pikas on our ascent.

The Flat Tops are more of a huge elevated plateau rather than a typical mountain range, but the plateau has been eroded into many individual peaks and summits, and most of them are flat-topped, or dome-like as are the Lost Lakes Peaks. The mountain area composing the Flat Tops contains over 110 lakes full of fish, and also has some of the most extensive areas above timberline in Colorado.

Getting There

There are two trailheads which allow easy access to “Ptarmigan Flat Top”. Both are reached via FR 900.

Mandall Lakes Trailhead

From Yampa, look for the sign on the west side of Highway 131 that points the way to "National Forest Access". Turn west on to County Road 7. Follow County Road 7 for seven miles, to where the road becomes FR 900. The parking lot is 12.7 miles from Yampa (the junction at Antler’s Inn) and is just beyond the Bear Lake Campgroud.

Stillwater Reservoir Trailhead

From Yampa, look for the sign on the west side of Highway 131 that points the way to "National Forest Access". Turn west on to County Road 7. Follow County Road 7 for seven miles, to where the road becomes FR 900. Stay on the main road for nine miles and drive to the parking area at Stillwater Reservoir. The road is good for all vehicles in day conditions. A 4wd may be needed early or late season.

The winter road closure for the routes above varies. From mid-November through mid-April, the road is closed where the pavement ends (10 miles from Stillwater). In late April, another 7 miles of the road opens allowing access to Bear Lake. In early June (when the snow finally clears) the last 3 miles of the road opens allowing access to Stillwater Reservoir.

Routes Overview

There are two major route possibilities for the ascent of “Ptarmigan Flat Top”. See the route pages for more details.

Via Mandall Creek

This is perhaps the easiest route up “Ptarmigan Flat Top”. A good trail is followed up Mandall Creek to near Black Mandall Lake. From there an indistinct trail is followed to Mandall Pass followed by an mostly easy cross country hike to the summit.

This route is 11 miles round trip with about 2500 feet elevation gain.

See the route page for details.

Via Stillwater Reservoir

This route is probably almost as easy as the route from Mandall Creek and has less elevation gain. It is mostly above timberline though, so a good weather forecast is essential. Once on the long undulating route to the summit, you will be the highest object around during a thunderstorm.

From the trailhead, the trail to Devils Causeway is followed to the saddle just northeast of the causeway itself. From there, the long ridge and plateau area is followed to the summit of “Ptarmigan Flat Top”.

This route is about 11 miles round trip and other than the first 1.5 miles is above timberline the entire way.

See the route page for details.

Camping

Campgrounds

CLICK HERE for current campground information for official Routt National Forest campgrounds. The ones in the Yampa River district are in the same general area as Flat Top Mountain.

The Cold Springs and Horseshoe campgrounds are located near Stillwater Resevoir. The Bear Lake campground is located near Bear Lake. And the East Marvine campground is located near Trappers Lake.

Backcountry Camping

There are many beautiful and ideal campsites between the area just before the trail reaches Mandall Creek (10,200 feet elevation) all the way up to the head of the basin below Mandall Pass. The lakes have excellent campsites, but they are also fairly popular. Bring insect repellent early season.

When to Climb

"Ptarmigan Flat Top" could be climbed year-round by an experienced climbing party, but the roads to Stillwater Reservoir is open only from around Memorial Day or early June to sometime in November, so outside this time period, this would probably be a three day trip.

The Flat Tops (especially the northern and western section) receive much snow, so despite the lower altitude than the 14'ers, the peaks remain buried in snow until mid-July. Snowshoes are recommended in June.

The Flat Tops have many mosquitoes in July, and sometimes into early August.

Mid August to mid September is good because the mosquitoes are gone.

From September and into December is hunting season, so wear blaze orange and use extreme caution. On the plus side, hunter traffic usually keeps the roads open until around Thanksgiving weekend. Late November might be the best time to make a “winter conditions” ascent because after the road closed, this would be very long trip.

Mandall Pass
