2016 Summer Mountain Trip Part 21; Colorado State Route 347, South Rim Road, and Black Canyon of the Gunnison National Park

After leaving Colorado National Monument via Monument Road and Colorado State Route 347 I made turn eastward on US Route 50 in Grand Junction.  My next destination was to the southeast at the end of Colorado State Route 347 at Black Canyon of the Gunnison National Park.


This article serves as the 21st entry in the 2016 Summer Mountain Trip Series.  Part 20 covers Colorado National Monument and Rim Rock Drive.

2016 Summer Mountain Trip Part 20; Colorado National Monument and Rim Rock Drive

The south entrance of Black Canyon of the Gunnison National Park (I'll be short handing to "Black Canyon" so it doesn't take to write from hereon in) is accessed by via the 5.2 mile long CO 347.  CO 347 begins east of Montrose and makes a fast ascent northward to the south entrance of Black Canyon near Jones Summit.  The route that ultimately became CO 347 was added to the State Highway System in 1939 but can be seen as a locally maintained road on the 1939 Rand McNally Highway Map of Colorado.


The first map that clearly shows CO 347 is the 1947 Shell Highway Map of Colorado.


Black Canyon of the Gunnison National Park protects a 12 mile portion of the namesake canyon along the Gunnison River.  Black Canyon is thusly named due to the fact that it's extremely steep nature only allows an average of 33 minutes of sunlight to reach it's bottom daily.  Black Canyon is the 5th steepest mountain side descent on the North American continent.  By comparison Black Canyon is about five times steeper than the Grand Canyon.

Although Black Canyon had been known to local tribes the first American to discover it was John Williams Gunnison in 1853.  In 1881 the Denver & Rio Grande Railroad had reached Gunnison and the route west was plotted through part of Black Canyon.  The first passenger train through the eastern segment of Black Canyon arrived in August of 1882.  Ultimately surveys recommended that the railroad was unfeasible through the steepest parts of Black Canyon it was instead routed to the south.  The Denver & Rio Grande Railroad can be seen being routed around most of Black Canyon on the 1882 New Railroad and County Map of Colorado.   In 1890 a new route of the Denver & Rio Grand Railroad through Glenwood Springs was constructed and the Black Canyon route began to decline before being ultimately abandoned in the 1950s. 


In March 1933 much of Black Canyon was declared a National Monument.  The Civilian Conservation Corps constructed the North Rim Road between 1933 through 1935.  The South Rim Road (which is the continuation of CO 347) appears to have been constructed around the same time.  Black Canyon was elevated to a National Park in October 1999 and currently encompasses 30,750 acres.

The South Rim Road has twelve view points beyond the terminus of CO 347.


The start of my drive on South Rim Road began with the intersection with East Portal Road.  East Portal Road heads towards the Gunnison Diversion Dam which I ultimately skipped in 2016.  My first stop on South Rim Road was at Tomichi Point which looks eastward into Black Canyon.


My next stop on South Rim Road was at the Park Visitor Center for a look from Gunnison Point.  I should note that the hiking trails through most of Black Canyon lie above an elevation of 8,000 feet and tend to be on the shorter side.


Next along South Rim Road I stopped at the Cross Fissures View.


South Rim Road begins to swing westward.  I stopped and hiked the Rock Point Trail out to the rim of Black Canyon.


Just west of the Rock Point Trail the Devil's Lookout Trail can be accessed from South Rim Road.


From the Devil's Lookout Trail I next stopped west on South Rim Road at the Chasm View.


From the Chasm View I hiked the Painted Wall Trail to the namesake formation.  Painted Wall is the tallest sheer cliff in Black Canyon at 2,250 feet.  The lighter rocks in Painted Wall is pegmatite.



From Black Canyon's south rim I turned to US 50 via CO 347.  My next destination was south on US 550 and the Million Dollar Highway.

Hetch Hetchy Valley; Hetch Hetchy Railroad, abandoned Lake Eleanor Road, and the Wapama Fall Bridge

This June I took a trip out to Yosemite National Park upon receiving my COVID-19 Day Use Reservation.  My destination in Yosemite National Park was out in Hetch Hetchy Valley.  I sought to hike to the Wapama Fall Bridge which took me through some of the path of the former Hetch Hetchy Valley Railroad and abandoned Lake Eleanor Road.



Part 1; Hetch Hetchy Valley, the Hetch Hetchy Railroad, and reservoir roads

Hetch Hetchy is glacially carved valley similar to Yosemite Valley which is located on the Tuolumne River of Tuolumne County.  Hetch Hetchy Valley presently is impounded by the O'Shaughnessy Dam which was completed during 1923 as part of a project to deliver water and hydroelectric power to the City of San Francisco.  Before being impounded Hetch Hetchy Valley had an average depth of approximately 1,800 feet with a maximum depth of approximately 3,000 feet.  Hetch Hetchy Valley is approximately three miles long and as much as a half mile wide.  Hetch Hetchy Valley is located dow…

Mineral King Road, the White Chief Mine, and the unbuilt California State Route 276

Back in July of 2016 I took Mineral King Road east from California State Route 198 to Mineral King Valley within the Sierra Nevada Mountains of Sequoia National Park.  This June I revisited Mineral King Valley and made my way up to the White Chief Mine.


Mineral King Road is a 24.8 mile rural highway maintained by the National Park Service and as Tulare County Mountain Road 375.  Mineral King Road originates at California State Route 198 in Three Rivers near the confluence of the Middle Fork Kaweah River and the East Fork Kaweah River.  Mineral King Road climbs from a starting elevation of 1,400 feet above sea level to 7,830 feet above sea level at the White Chief Mine Trailhead in Mineral King Valley.  Notably Mineral King Road is stated to have 697 curves.


Mineral King Road has an average grade of 5.1% but has several stretches between 15-20% in places.  Pjammycycling has a detailed breakdown on the grade levels over the entirety of Mineral King Road.

California's Rogue Sign State Route Shields

While recently revisiting Yosemite National Park I took a couple minutes to capture some of the California Sign State Route shields posted by the National Park Service ("NPS").  None of the NPS shields were actually posted on roadways maintained by Caltrans but were clearly intended to create route continuity with the Sign State Highways.  This phenomenon is not exclusive to Yosemite National Park and can be found on numerous roads not maintained by Caltrans throughout California.



Part 1; Route continuity over who maintains the route

In the very early era of State Highways in California the Division of Highways didn't actually field sign the Auto Trails or even US Routes.  The responsibility of Highway signage fell to the California State Automobile Association ("CSAA") and Automobile Club of Southern California ("ACSC").  The Auto Clubs simply signed Highways on roadways that best served navigational purposes.  These navigational purposes often didn&#…
