California State Route 158; the June Lake Loop

After returning to US 395 via CA 270 from Bodie I headed south towards Mammoth.  Along the way I detoured off of US 395 onto CA 158 which is known as the June Lake Loop.  CA 158 is a 16 mile loop route in rural Mono County to/from US 395.  Only the 3.5 southern most miles of CA 158 are kept open during the winter while the rest of the route closes for the winter.  I started CA 158 from the north terminus and headed south. 


Apparently the slab of asphalt behind the guide sign was once an alignment of US 395.


The views of the Eastern Sierras approaching Grant Lake are stunning, especially after a heavy winter like early 2017.



After crossing a small ridge CA 158 begins to run along the shore of Grant Lake.



CA 158 follows the shore of Grant Lake before descending through a small canyon to Silver Lake.





Approaching Gull Lake there is much more buildings and population alongside CA 158.


CA 158 enters the incorporated community of June Lake.



CA 158 runs along the south shore of June Lake (the lake, not the community).


CA 158 drops in elevation before reaching it's southern terminus at US 395.




I stopped at June Lake Junction for lunch since the deli has pretty good sandwiches.  I noticed a really exacting license plate in front of the deli that had a clear connection to CA 158.


 There was also a incredibly rate Cadillac Durango H2 present at June Lake Junction.


The drizzle I ran into over Tioga Pass earlier in the day finally caught up to me as I was taking photos of the Sierras from June Lake Junction.


CA 158 was originally unsigned Legislative Route Number 111 before the 1964 California Highway Renumbering.  CA 158 is essentially unchanged from the original alignment which was adopted in 1933 which can be seen on the 1935 California Division of Highway Mono County Road Map.

The change from unsigned LRN 111 to CA 158 can be seen on the 1963 and 1964 State Highway Maps:

1964 State Highway Map:

From the north terminus there are four lakes on CA 158; Grant, Silver, Gull, and June.  Apparently all the lakes are sub-alpine and are fed from creeks emptying out of the eastern Sierras.  The section of roadway south from the north terminus of CA 158 was constructed during 1915 to Silver Lake for a hydroelectric project on Rush Creek.  The roadway from the southern terminus was built from June Lake Junction, past June Lake, to Silver Lake by 1924.  By 1927 there was enough people living at June Lake to warrant postal service.

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&#…
