Mosquito Pass was built to connect the towns of Alma to the east, with Leadville to the west. It is the highest crossable vehicle mountain pass in the U.S. outside of Alaska. While there are higher vehicle passes, they are all out and back. The trail crosses the Continental Divide,  between the Arkansas and South Platte Rivers.

The Mosquito Range is also home to five 14,000′ peaks;  Mt Sherman Mt Democrat, Mt Cameron, Mt Lincoln, and Mt Bross.

Stony Pass Rd crosses the Continental Divide and follows small streams that make up the headwaters of the Rio Grande River. The road was created in 1872 to connect the area’s mining operations in Silverton to the town of Del Norte. The Continental Divide Trail crosses the road at Hunchback Pass (12,493′) on it’s way from Mexico to Canada.

The San Juan Range is home to world class outdoor recreation. American Basin, California & Hurricane Pass, and Mt Sneffels are a few examples of the natural beauty of the area.

 

The road crosses the headwaters of the Rio Grande near Kite Lake.

County Road 3 to Stony Pass (heading east) is a well graded and a easy drive to the top in a stock vehicle (in good weather). Once on the east side of the pass, an off-road vehicle is recommended because the road gets progressively more difficult until Kite Lake.

Pole Creek, a water crossing on the east side of the pass, can be very deep in the spring, making it impossible to cross.

Route Directions

Start by accessing Hayden Pass RD (FR 6) from Coaldale on the east side of the Sangre de Cristo mountains or from Villa Grove on the west side.

The pass is more difficult if started on the west side (Villa Grove) because you are climbing on a very rocky trail.

Hayden Pass summit is a large flat area after a continuous climb. The views from the road here are blocked by thick forest.

The road on the east side of the pass is better maintained and not as rocky.

Tincup Pass (12,154′), Sawatch Range

Tincup Pass gets its name from prospector Jim Taylor, who in 1860 brought his gold strike back to camp in his tin cup. The pass was used to move supplies between St. Elmo and the town of Tin Cup starting in 1881, when a wagon road was built.

The views and hiking opportunities along the road are abundant. There are 13,000′ peaks that can be easily accessed from 267 (Tin Cup Peak, PT 13,050, and Fitzpatrick Peak). In addition, the prominent Continental Divide Trail and Colorado Trail cross Tin Cup Pass Rd (267) about 4 miles from St. Elmo.

The Sawatch Mountain Range is home to fifteen 14,000′ peaks, such as Huron Peak, La Plata Peak, Missouri Mountain, Mt Antero, and the highest peak in the Rocky Mountains, Mt Elbert.

Starting from the south side of the pass at St. Elmo, the 4WD road climbs west toward Tincup Pass following the North Fork of Chalk Creek.

After 4 miles the road climbs to the north toward Tincup Pass.

Another mile in brings you to treeline with a good view of the remainder of the route to the pass. The switchbacks ahead are very narrow.

Once up the ledge road and switchbacks you will be at Tincup Pass, about 6 miles from St. Elmo.

Heading down the north side of the pass, the road is rough for the first mile while it winds through the tundra.

The road gradually widens and becomes more maintained.

After crossing a creek you will drive on a section of road made up of large talus along the edge of Mirror Lake. This section is rough so use caution.

Once past the lake the road becomes passable by passenger vehicles.

Mt Antero (14,269′) and Mt White (13,667′), Sawatch Range

Mt Antero is one of only a handful of 14,000′ peaks that has a road that travels to within a short distance of the summit.  The road up the mountain is difficult, rough and rocky, requiring four-wheel drive, eventually topping out at 13,800′. From the end of the road at point 13,800 it’s a 1/2 mile and 470′ scramble to the summit.

In 1881, a Salida man by the name of Nelson Wanemaker discovered gems high on Mt Antero. His discovery was publicized a few years later, and the mountain became a famous collecting area for aquamarine, phenacite, fluorite, topaz, and smoky quartz crystals. It has the highest concentration of these minerals anywhere in the US. With findings far above timberline, this is the highest known gem field in the lower 48.

The Sawatch Mountain Range is home to fourteen other 14,000′ peaks, such as Huron Peak, La Plata Peak, Missouri Mountain, and the highest peak in the Rocky Mountains, Mt Elbert.

Hurricane Pass (12,730′) and California Pass (12,960′), San Juan Range

The National Water and Climate Center reported that the SWE (snow water equivalent) for the San Juan Mountains, including Hurricane Pass and California Pass, in May of 2019 was 728% above normal. It was such a heavy snow year that most of the back country at higher elevations was still buried in July. The heavy amounts of snow also caused a significant number of avalanches in the state. The only option out of Silverton to the Alpine Loop this July was to take SH 100 to Gladstone. Heavy avalanche debris still blocked the route to Animas Forks from Silverton using County Rd. 2.

Heading out of Silverton on SH 110, you pass Gladstone, which sits in a flat meadow where the five forks of Cement Creek meet. The town began in the late 1870’s from the surrounding mines including a sawmill just below the town site. As the mines grew, the sawmill was needed by other mines in the area, so a wagon road was graded up Cement Creek. In 1879 this wagon road went over Hurricane Pass and down Poughkeepsie Gulch as the route from Silverton to Ouray.

Today Poughkeepsie Gulch is generally for high clearance 4×4 vehicles that don’t mind a few road scars. The route today includes Hurricane and California Pass, and eventually leads down to Animas Forks.

The San Juan Mountains offer incredible outdoor beauty, including areas such as American Basin, Mt Sneffels, and Stony Pass.
