Dalkes Couloir
Ogalalla Peak from Elkstooth showing our line of ascent in 1972. We were told then, it was named "Dalkes Couloir" presumably because Larry Dalke had done the 1st ascent.

Ogalalla Peak via ‘’Dalkes Couloir’’
Rocky Mountain National Park
Elevation: 13138 ft / 4004 m
Best months to climb: Mid May through mid July.
Difficulty: Steep snow

Located at the southwest corner of Wild Basin, this remote summit is the southernmost thirteener in Rocky Mountain National Park and overlooks four separate draineges. It is the highest for many miles around, and because every approach is long, it sees few ascents. It is connected to Elk Tooth by rugged ridge spiked with rock towers.
Snow Line

Ogallala is rugged, challenging and rewarding peak.
The peak got named officially in 1914. Like other summits in the IPW, it bears the name of a Native American tribe. In the Lakota language "Ogalalla" means "they scatter their own." There are a few spelling variants, including Oglala and Ogallala. The boundary between RMNP and IPW ran north of Ogalalla Peak, before it was moved to coincide with the watershed between Wild Basin to the north and the Middle Saint Vrain Creek drainage to the south. Wild Basin is the drainage of the North Saint Vrain Creek.

From the junction of Middle Saint Vrain Road and Colorado 72, go west 1.2 miles on Middle Saint Vrain Road to the trailhead.
The Buchanan Pass Trail climbs west on the north side of Middle Saint Vrain Creek and a 4WD road climbs west on the south side of the creek. With a 4WD vehicle you can drive west an additional 4.0 miles to the Indian Peak Wilderness boundry and reduce the hiking mileage to either Buchanan Pass or Saint Vrain Glaciers.
This road is really is a 4WD road and passenger cars will not make it.

There are several camping sites within Rocky Mountain National Park and specifically in Wild Basin. It is usually easier to get permits for Wild Basin than for the rest of the park. Details on locations, facilities, reservations, and fees can be found at the camping page of RMNP. Bivy information can also be found on the park's site.

The Indian Peaks Wilderness is divided into zones. Different restrictions apply to different zones, and the rules in effect depend on the time of the year. Refer to the Indian Peaks page for camping sites, rules, and printable forms

Mountain Conditions

The Indian Peaks' contact information page and the Rocky Mountain National Park's contact information page list useful addresses and phone numbers. Two webcams, one pointed at Longs Peak and the other at a stretch of the Continental Divide, and a webcam on Niwot Ridge also allow one to get an idea of the conditions not far from Ogalalla Peak. Detailed forecasts are provided by NOAA.
Never forget that the weather may change very rapidly in the high country. The temperature may drop by 50°F or more in a couple of hours. Those who have been caught out by such sudden changes without proper equipment and preparation have not always survived.
