Crossroads of the Rockies


Saguache & Chaffee County line at Poncha Pass

The Crossroads of the Rockies are where Hwy’s 50 and 285 intersect at Poncha Springs in Chaffee County, Colorado in the Heart of the Rockies.

X-Roads of the Rockies, a Dual Sport, Singletrack and Adventure ride in August takes place from the Chaffee County Fairgrounds at the Crossroads of the Rockies.

US Route 285 (US 285) is a north–south U.S. highway that runs from Sanderson, TX to Denver, CO. In the state of New Mexico, US 285 runs through the major cities of Carlsbad, Roswell, and Santa Fe. The highway enters into the state Colorado near the small town of Antonito on Colorado’s southern border with New Mexico.

In Nevada, Hwy 50 is called “The Loneliest Road in America”

U.S. Route 50 (US 50) is a part of the Intercontinental U.S. Highway System and travels from West Sacramento, California, to Ocean City, Maryland.

In the state of Colorado, US 50 is a major highway crossing through the lower midsection of the state. It connects the Western Slope with the lower Front Range and the Arkansas River Valley. The highway travels through the cities of Pueblo and Grand Junction as well as many other smaller towns & areas along its corridor.

Highway 50 is one of the least traveled Coast to Coast Highways.

Highway 285 travels through a pretty desolate region of the Country. Until it reaches Denver.

The Crossroads of the Rockies are near the Watersheds of 4 major Rivers. The Arkansas, Rio Grande, Colorado & South Platte.



Narrow Gauge Steam Train in the Northern San Luis Valley in the 1920’s

In New Mexico Hwy 285 partially follows the old Chili Line, officially known as the Santa Fe Branch, a narrow-gauge branch of the Denver and Rio Grande Western Railroad (D&RGW). It ran 125.6 miles from Antonito, Colorado, to Santa Fe, New Mexico. The D&RGW closed the Chili Line in 1941 and the line was abandoned shortly thereafter.

The Historic Narrow Gauge Cumbres & Toltec Scenic Railroad is a still in existence narrow gauge tourist train that departs from the nearby small town of Antonito and Hwy 285.

Heading north from the Colorado/ New Mexico border, US 285 passes through the center part of the San Luis Valley, eventually reaching the city of Alamosa. Alamosa was a division point and maintenance yard for the Denver & Rio Grande Railroad from the late 1800’s. Alamosa is the largest city in the entire San Luis Valley and is home to Adams State University.

Rock formation in Penitente Canyon near La Garita

As Highway 285 continues it passes through the farming community of Monte Vista, bypasses La Garita and historic Penitente Canyon, and then dissects the historic town of Saguache, where the Highway begins to ascend to the northern end of the valley. The Highway follows the Valley Line of the DRG&W and eventually climbs over Poncha Pass, elevation 9,010 feet and drops sharply down the other side into the Arkansas River Valley. Hwy 285 follows portions of the old DRG&W line over Poncha Pass. 

Narrow Gauge Steam Train on Poncha Pass at Mears Junction in the 1920’s

Poncha Pass is a division point of the Watersheds of the Rio Grande and Arkansas Rivers. Poncha Pass also included the division point at Mears Junction of the Marshall Pass and Valley Line Narrow Gauge DRG&W Railroad routes back in the day.

At the bottom of Poncha Pass Hwy 285 intersects Hwy 50 at the Crossroads of the Rockies in Poncha Springs. The small town of Poncha Springs lies about 6 miles north of the pass. Poncha Pass has a steeper but still mild approach on the northern side and a moderate 5% approach from the south.

Poncha Pass lies on the border between Chaffee County and Saguache County, (Sawatch) and on the dividing line between the San Isabel and the Rio Grande National Forests.

Poncha Springs Townhall

The Poncha Springs Schoolhouse, which is listed on the National Register of Historic Places and now serves as the town hall, was completed in 1883.

The Castles on Trout Creek Pass

Highway 285 brushes past Salida and follows the Arkansas River north up the valley about 20 miles, then takes a sharp eastward turn just before the small town of Buena Vista at the foot of the Collegiate Peaks . Hwy 285 then merges with Hwy 24 and climbs over Trout Creek Pass, following the old Denver, Southpark Pacific Railroad line to an elevation of 9,346 feet, then enters the high-altitude South Park basin.

A few miles north, the highway passes through Fairplay and the historic South Park City site, then reaches its highest elevation: 10,051 feet at the summit of Red Hill Pass. US 285 then leaves the South Park basin and climbs over Kenosha Pass, elevation 10,001 feet and skirts the south side of the Mount Evans massif as it descends its way through the foothills range towards Denver.



Monarch Pass is the highest point on Hwy 50

From East of Gunnison Highway 50 follows portions of the old DRG&W railroad line from Grand Junction to Marshall Pass through the communities of Parlin and Sargents and then ascends to Monarch Pass (elevation 11,312 feet) on the Continental Divide. Monarch Pass is the highest point on the entire 3,017 mile length of U.S. 50, which was built in 1926.

The Arkansas River Valley

After descending from Monarch Pass and the south fork of the Arkansas River, Highway 50 enters the Arkansas River Valley at the town of Poncha Springs, where it crosses Hwy 285 and continues east toward the town of Salida, which is the County seat of Chaffee County. The northern fork of the headwaters of the Arkansas River is about 50 miles north near Leadville, at the Climax mine molybdenum ore deposit.

East of Salida, the highway enters a deep canyon, dubbed Bighorn Sheep Canyon. There are several small communities and old Railroad stops in the canyon including Swissvale, Howard, Coaldale, Cotopaxi and Texas Creek.

Cotopaxi General Store

The Arkansas River which begins its exit of the mountains at Salida (which means ‘Exit’ in Spanish) is the second-longest tributary to the Mississippi River system. U.S. Hwy 50 traverses the South side of the river in the canyon while closely following the Tennessee Pass Railroad line on the North bank of the river down the canyon .

The DRG&W line was known as the Scenic Line of the World.

Parkdale, Colorado 1911

Before the highway climbs uphill and leaves the canyon, it passes thru Parkdale, Colorado, a mining and a recreational area along the river.

The Royal Gorge Bridge was built in 1929

A short distance later, the hwy crosses the Arkansas River and enters the Royal Gorge area and its famous suspension bridge. The Royal Gorge Bridge is 1,260 feet long and 956 feet above the Arkansas River. It was built in 1929 and remains a popular tourist attraction.

After passing by the Royal Gorge, Highway 50 lowers off Eight Mile Hill and becomes a divided four lane highway. It then passes by the scenic route Skyline Drive on its way into Cañon City. ADX Supermax Prison, the only federal Supermax prison in the United States is located southeast of Hwy 50 & Canon City at Florence, Colorado.

The highway then enters Pueblo West on its way to intersect with Interstate 25. The city of Pueblo is at the edge of the Rocky Mountains, at the beginning of the plains of southeastern Colorado. As Highway 50 heads east across the plains, it generally follows the path of the Arkansas River until it reaches Kansas.


The name “Arkansas,” which had applied only to the lower reaches of the river, was carried westward by American traders and trappers.

The upper portion of the Arkansas River cascades out of the rugged Rocky Mountains and drops 10,000 feet in only 125 miles. After the Arkansas River rushes through the Royal Gorge at Cañon City, Colorado, it widens and flattens dramatically.

The river served as the boundary between the United States and Mexico from 1820 to 1846, while the Santa Fe Trail followed the Arkansas River through much of Kansas.

The Arkansas River is a major tributary of the Mississippi River. At 1,469 miles, the Arkansas is the sixth longest river in the United States, and the 45th longest river in the world.

The river’s origin is in the Rocky Mountains in Lake County, Colorado, near the town of Leadville.
