McKinley Grove Road to the Wishon Reservoir, Courtright Way to the Courtright Reservoir, and a dog named Dinkey

This past week the forecast high in Fresno was 109F.  Given that I wasn't in the mood to sit around a sweltering City on a day off I decided to take a day trip to the Sierra Nevada Mountains and Sierra National Forest.  My journey into Sierra National Forest would take me on McKinley Grove Road/Forest Road 11s040 and Courtright Way/Forest Road 10s016 to locales such as; the 1938 Dinkey Creek Bridge, the McKinley Grove of Sequoias, the Wishon Reservoir, and Courtright Reservoir. 



Part 1; McKinley Grove Road, a dog named Dinkey, the 1938 Dinkey Creek Bridge, the McKinley Grove, and Wishon Reservoir

My approach to McKinley Grove was eastbound from Dinkey Creek Road.





From Dinkey Creek Road there is a mileage sign showing that the Wishon Reservoir is 16 miles to the east whereas the Courtright Reservoir is shown to be 21 miles away.  McKinley Grove Road is maintained as Forest Road 11s040 and ends approximately 18 miles east of Dinkey Creek Road beyond the Wishon Reservoir at Little Rancheria Creek.


McKinley Grove Road eastbound begins with a quick crossing of Dinkey Creek at a starting elevation of approximately 5,987 feet above sea level.  On the east bank of Dinkey Creek the Dinkey Creek Day Use Area can be found which is a popular fishing locale.




McKinley Grove Road eastbound intersects Dinkey Fisherman Road/Forest Road 10s453 just beyond the Dinkey Creek Day use area.  Dinkey Fisherman Road is the original alignment of McKinley Grove Road and sometimes appears as "Old McKinley Grove Road" on some maps.


A quick detour onto Dinkey Fisherman Road reveals the Dinkey Fisherman Picnic Area and the 1938 Dinkey Creek Bridge.






The 1938 Dinkey Creek Bridge as noted above is the only Bowstring Arch Truss structure in California.  The 1938 Dinkey Creek Bridge was largely built to encourage tourism to the McKinley Redwood Sequoia Grove and interior of Sierra National Forest.  The 1938 Dinkey Creek Bridge was replaced by a new structure in 1956 to downstream to facilitate construction of the Wishon and Courtright Reservoirs. The 1938 Dinkey Creek Bridge was closed automotive traffic in 1965 and was restored in 1988. The 1938 Dinkey Creek Bridge was placed on the National Register of Historic Places in 1996. The namesake Dinkey Creek is named after a dog during the California Gold Rush in 1863 which attempted to fight a grizzly bear and lost.  The 1938 Dinkey Creek Bridge is 92 feet long, the two photos below are looking north upstream on Dinkey Creek.



I crossed the 1938 Dinkey Creek Bridge westward into the community of Dinkey Creek.







Dinkey Creek is a former sawmill community which essentially exists now to cater recreation opportunities at the namesake creek.   There was a large logging operation at Dinkey Creek operated by the Pine Logging Company from 1937 through 1979.   The community of Dinkey Creek can be seen on the 1935 Division of Highways Map of Fresno County at the eastern terminus of Dinkey Creek Road.


The western approach of the 1938 Dinkey Creek Bridge has a historic plaque on one of the barrier rocks.



Returning to McKinley Grove Road the route eastbound begins to ascend.  A small bridge can be found at Bear Creek which had a very active waterfall from the winter snow melt.














McKinley Grove Road east of Bear Creek ascends to the McKinley Grove of Redwood Sequoias.  The McKinley Grove is 5.8 miles east of Dinkey Creek Road and can be found at an elevation of 6,316 feet above sea level.










The McKinley Grove was discovered by settlers during 1869 and was originally known as the General Washington Grove.  The McKinley Grove is a somewhat small Sequoia Grove containing 216 trees and has never been logged.   The largest Sequoia in McKinley Grove is about 230 feet high and is approximately 2,000 years old.  The McKinley Grove was added to Sierra National Forest during 1893 and for a time was known as Dusy Grove in honor of explorer Frank Dusy.  The McKinley Grove took it's modern name in the early 1900s.  The name "McKinley Grove" is meant to honor the 25th President William McKinley.  The present McKinley Grove Trail was constructed in 1990.



































East of McKinley Grove the route of McKinley Grove Road passes by the Gigantea Campground.




East of the Gigantea Campground the route of McKinley Grove Road opens onto a clearing from where San Joaquin Valley can be seen below.  Given the poor weather in San Joaquin Valley the view obstructed the Diablo Range via a haze of dust.


McKinley Grove Road eastbound continues to ascend and passes through Brush Meadow at 6,720 feet above sea level.





Brush Creek essentially serves the half-way point of McKinley Grove Road as looking westbound shows it is 9 miles from Dinkey Creek Road.


McKinley Grove Road continues eastward as passes by the Buck Meadow Campground.









East of Buck Meadow the route of McKinley Grove Road intersects the infamous Blackrock Road/Forest Road 11s012.





From Blackrock Road the route of McKinley Grove Road begins to descend and intersects Courtright Way/Forest Road 10s016.







McKinley Grove Road eastbound passes through the Pacific Gas & Electricity ("PG&E") Wishon Camp and descends to Wishon Dam. 












Wishon Dam forms the namesake Wishon Reservoir by way of impounding the North Fork Kings River.  Wishon Dam was completed during 1958 by PG&E and serves the bridging structure for McKinley Grove Road.  Wishon Dam is an earthen structure which lies at an elevation of 6,554.9 feet above sea level, is 3,328 feet in length and 265 feet high from the foundation.   McKinley Grove Road crosses atop Wishon Dam on a one-lane alignment.


















 
McKinley Grove Road crosses over the spillway of Wishon Dam on a one-lane bridge.









I made a brief stop at the Coolidge Meadow Fishing Area before turning westward over Wishon Dam via McKinley Grove Road.









Part 2; Courtright Way to the Courtright Reservoir

Upon passing through Wishon Village I made a right hand turn from McKinley Grove Road westbound onto Courtright Way northbound.


From McKinley Grove Road the route north to the Courtright Reservoir on Courtright Way is approximately 7.4 miles.  Courtright Way is maintained as Forest Road 10s016 and is largely a one-lane paved roadway.


Courtright Way northbound begins with a fast climb to an approximate peak elevation of 8,600 feet.  Upon peaking in elevation Courtright Way emerges onto a switchback which overlooks the Wishon Reservoir.























Courtright Way passes by the Leconte Divide Overlook.  The Leconte Divide is a topographical line of peaks in the Sierra Nevada Mountains which separate the Kings River Watershed from the San Joaquin River Watershed.  The 13,568 foot high Mount Goddard can be observed from the Leconte Divide Overlook.  









Courtright Way continues northward snaking through the terrain and emerges onto a three-way road fork at the Courtright Reservoir.  Left at the fork continues on Courtright Way towards a PG&E encampment, the center road is Marmot Rock Campground Road/Forest Road 10s096 which leads to a boat launch, the right road is Courtright Dam Road/Forest Road 09s038 which heads to Courtright Dam.










I turned right onto Courtright Dam Road which has signage directing traffic to the Dusy Ershim OHV Trail/Forest Road 07s032 and Maxson Trailhead.



Courtright Dam Road is a single lane and begins by crossing a concrete slab over the Courtright Dam spillway.








Courtright Way crosses Courtright Dam via a one-way alignment.  Courtright Dam impounds Helms Creek and was completed alongside Wishon Dam by PG&E during 1958.  Courtright Dam is a earthen structure which lies at 8,170 feet above sea level and has 315 feet height from it’s base.  Atop Courtright Dam looking south reveals a wide vista above Helms Creek.  The formation known as the Power Dome can be seen on the east bank of Helms Creek.







Upon crossing Courtright Dam I climbed down the east bank of Helms Creek to get a better view of the structure.





Suffice to say few roads have quite the intimidating view and drop off that Courtright Dam Road does.


Before heading towards Fresno I did stop at the boat launch on Marmot Campground Road for brief lunch overlooking the Courtright Reservoir.

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l

Ghost Town Tuesday; Mannfield, FL and the stairway to Hell

Back in 2015 I went searching the Lecanto Sand Hills for the original Citrus County Seat known as Mannfield.  Unlike Centrailia in Hernando County and Fivay in Pasco County I did find something worth seeing. Mannfield is located in the Lecanto Sand Hill section of Withlacoochee State Forest somewhat east of the intersection of Citrus County Route 491 and Mansfield Road. Mannfield was named after Austin Mann and founded in Hernando County in 1884 before Citrus County Split away.  In 1887 Citrus County was split from northern Hernando County while Pasco County was spun off to the south.  Mannfield was selected as the new Citrus County seat due to it being near the county geographic center.  Reportedly Mannfield had as many as 250 people when it was the County Seat.  The town included various businesses one might include at the time, even a sawmill which was common for the area.  In 1891 Citrus County voted to move it's seat to Inverness which set the stage for the decline of M

The National Road - Pennsylvania - Great Crossings Bridge and Somerfield

West of Addison, US 40 crosses the Youghiogheny River at what once was the town of Somerfield.  When crossing the current modern two lane bridge, you many not realize that it is actually the third to cross the Yough at this site.  The first - a stone arch bridge - was known as the Great Crossings Bridge.  Built in 1818, this three arch bridge was part of the original National Road.  The name Great Crossings comes from the men who forded the Youghiogheny here - George Washington and George Braddock. (1)  If you cross the bridge at the right time, this historic bridge and what was once the town of Somerfield will appear out from underneath this massive man-made lake. Historical Postcard showing the 'Big Crossings' bridge and Somerfield.  Image submitted by Vince Ferrari. The Great Crossings Bridge was located in the town of Somerfield.  Somerfield, originally named Smythfield until 1827, would develop as a result of the National Road.
