The Mountain Loop Highway is a highway in the U.S. state of Washington. It traverses the western section of the Cascade Range within Snohomish County. The name suggests it forms a full loop, but it only is a small portion of a loop, which is completed using State Routes 92, 9, and 530. Part of the highway is also a designated and signed Forest Highway, and is known as Forest Route 20. [1]

Contents

The highway connects the towns of Granite Falls and Darrington. It is paved for 34 miles (55 km) from Granite Falls to Barlow Pass (2349') where the highway becomes unpaved for 13 miles (21 km), and then paved again for the remaining 9 miles (14 km) to Darrington. The unpaved section is U.S. Forest Service Road #20 and passes several USFS campgrounds. Portions of the unpaved section are often closed for periods of several years due to flood damage.

Between Granite Falls and Barlow Pass, the highway passes Big Four Mountain and the trailhead leading to the Big Four Ice Caves at its base. At Barlow Pass, a gravel road maintained by Snohomish County [5] (closed to motor vehicles) branches from the highway and leads to the former silver mining town of Monte Cristo. The portion from Granite Falls to Barlow Pass follows the Stillaguamish River. The portion from Barlow Pass to Darrington follows the Sauk River. The "inside" of the highway's namesake loop is a large area containing significant Cascade peaks, including Three Fingers (6,850 ft; 2,090 m), Whitehorse Mountain (6,850 ft; 2,090 m), Mount Dickerman (5,723 ft; 1,744 m), and Mount Forgotten (6,005 ft; 1,830 m).

The Mountain Loop Highway starts at the eastern end of SR 92 in Downtown Granite Falls. Within Downtown Granite Falls, SR 92 is called E Stanley Street and the Mountain Loop Highway is known called N Alder Street. [6] The highway goes north away from Granite Falls and turns east at the point where the road meets the South Fork of the Stillaguamish River. From there, the road roughly follows the river and intersects some Forest Routes such as FR 4201, FR 4018, FR 4020, FR 4037, FR 4052, and FR 4059 while traversing the communities of Robe, Verlot, and Silverton before the river ends. [7] The loop continues and intersects a private road that connects the highway to the Old Monte Cristo Townsite, which is located 4 miles east of Barlow Pass.

Unpaved segment

At Barlow Pass, the Mountain Loop Highway goes north, and becomes unpaved Forest Route 20 or FR 20. Shortly after becoming unpaved, FR 20 starts to follow the Sauk River towards Darrington. FR 20 goes northward past Bedal, and it becomes paved again at the new Whitechuck bridge (approximately mile marker 44). [8]

Paved segment 2

From Whitechuck, the Mountain Loop Highway continues north along the Sauk River. On the opposite side of the river, the N. Sauk River Road (Forest Route 22) parallels the route of the Mountain Loop Highway. The loop enters Darrington, where Railroad Avenue splits from the highway to become a short bypass to the eastern end of the highway. The highway ends at SR 530. [9] [10]

History

The Mountain Loop Highway was established on March 23, 1936. Before the highway was built, primitive and very rough wagon roads connected the Monte Cristo Townsite with the small towns of Darrington and Granite Falls. A narrow wagon road, known as Wilmans Trail or Pioneer Trail, or simply the Sauk wagon road, was built from Sauk City on the Skagit River to Monte Cristo in 1891. That same year, the surveyor M.Q. Barlow discovered the feasibility of access to Monte Cristo via the South Fork Stillaguamish River. Mining interests funded a wagon road from Silverton to the Sauk wagon road via Barlow Pass. [11] These roads roughly followed the current route of the Mountain Loop Highway along with some railroads. Construction of the road started in 1936 and finished in 1941. The road was closed in 1942 due to the World War II. [4]

The highway closes mostly in the winter due to floods and reopens in the spring of the following year, but a windstorm in 2003 closed the highway. With other windstorms following in 2006 and 2007, the highway had to be closed until 2008. [12]

The Mountain Loop Highway officially reopened on June 25, 2008, and the cities along the full loop (Arlington, Granite Falls, and Darrington) had a large celebration. [12] [13] [14] [15]

Major intersections

The entire highway is in Snohomish County.

Big Four is a 6,160+ feet mountain summit in the Cascade Range, located about 20 miles (32 km) east of Granite Falls, Washington. It is situated 4 miles (6.4 km) west of Barlow Pass along the Mountain Loop Highway, near the Monte Cristo area, on land administered by the Mount Baker-Snoqualmie National Forest. Debris piles on the mountain's northern flank form as a result of avalanche activity. These fields of disturbed snow are able to remain year round in the shadow of the mountain. During the summer months snow-melt streams flow beneath the debris piles and cause caves to form in the ice. The caves vary in size from season to season and are unpredictably dangerous. The mountain is open to the public and a large snowfield can be reached by a short trail, but the snowfield itself is off-limits due to cave-ins and slides which have killed hikers in incidents in 1998, 2010, and 2015.

<span class="mw-page-title-main">Everett and Monte Cristo Railway</span>

The Everett and Monte Cristo Railway was built to transport gold and silver ores from mines in the central Cascade Mountains to a smelter in Everett, Washington. After the first mining claims were staked in 1889, entrepreneurs began exploring the possibility of building a railroad to exploit the find. Construction began in April 1892 and the first train reached what became the town of Monte Cristo in August 1893. The mining boom ended in 1903. Poor ore quality and quantity played a role in the decline, but the failure of the railway to maintain service to Monte Cristo in the face of floods, landslides, winter snows, fires, and other disasters was also a factor in the collapse of the industry. Nonetheless, the railway hauled out approximately 300,000 tons of ore over the course of its operations.

<span class="mw-page-title-main">Del Campo Peak</span> Mountain in Washington (state), United States

Del Campo Peak is a prominent summit near the western edge of the North Cascades, in Snohomish County of Washington state. It is located south of Barlow Pass along the Mountain Loop Highway near the Monte Cristo area. It is situated on land administered by the Mount Baker-Snoqualmie National Forest. The mountain is named for a mining claim on the mountain's slope. The nearest peak is Gothic Peak, 0.5 miles (0.80 km) to the southwest, and Foggy Pass is the low point between the two peaks. Foggy Lake lies in Gothic Basin below the south face of Del Campo Peak and collects precipitation runoff which ultimately drains to South Fork Sauk River via Weden Creek. Runoff from the west side of the mountain drains into the Sultan River, and the north side drains into headwaters of the Stillaguamish River. In terms of favorable weather, the best months for climbing are July through September.
