A little bit of this, a little bit of that
During the past couple of months, I have spent what little bit of free time I’ve had chasing down some benchmarks, determining the early routing of US 97 through Weed, California, and doing a little exploration of former US 99W and US 99E. I still have some research to do on the aforementioned section of US 97, as well as some pictures to take, but I hope to have a post up in the next month or so on that subject. If you are a member of the Facebook group “California Historic Highways” you’ve seen some results of my research already posted to that group in the past few weeks.
Segment of first routing of the Pacific Highway, then US 99, then US 99W, just south of Yolo County Line Road, just east of Interstate 5. This pavement probably dates from 1925. I haven’t yet researched when the more modern and straighter alignment was built to the left, but I suspect sometime around the late 1930s. Photo taken 24 February 2022.
Benchmarks: I added benchmark W 494 to the Siskiyou County, California Survey Marks page. This benchmark is near the first routing of US 97 outside of Weed, after the southern terminus of 97 was moved from Ashland, Oregon, to Weed in 1934.
I also added new pages for Butte and Tehama counties in California. The first benchmark listed in the Butte County page is near the crossing of an abandoned branch of the Sacramento Northern Railway over CA State Route 99 (ex-US 99E).

New blog post: Lake Shasta Artifacts, 9 December 2021. A visit to a segment of historical US 99 left high and dry by the receding waters of Lake Shasta, as well as a railroad tunnel that is also accessible.
Update to the Union Pacific Railroad: Black Butte Subdivision page in the Abandoned Railroad Infrastructure section. I’ve identified a number of straightened curves between Dunsmuir and the Black Butte siding that I’m checking out.

At the beginning of November, I made a trip down to Lake Shasta to explore some of the old infrastructure uncovered by the drought conditions much of the West has been suffering from in the past couple of years. Lake Shasta has been a levels only really seen in the past decades – 2014, I believe, and the great drought of 1976-77. Stuff that has emerged from the waters include old highways, bridges, and railroad beds and tunnels. Unfortunately, much of the area surrounding the lake was engulfed in wildfires throughout this past summer, with national forest closures making access to much of the lake and these historic sites pretty tough.
At the beginning of November, I was finally able to make it down to the lake and spend a few hours exploring a couple of sites of interest with a fellow roadgeeker, Eric Hall, from Redding.
Bailey Cove
This spot is located in a drainage off the west side of the McCloud River Arm of Lake Shasta. The 1915 Pacific Highway and the 1926 US 99 routing drops off a ridge heading south down to the McCloud River, then along the north side of the Pit River, until it crossed the Pit near what is now Bridge Bay, under the shadow of the present I-5 Pit River Bridge. This routing was replaced when Shasta Dam was built and required that US 99 be moved to higher ground, along with 26 miles of Southern Pacific trackage. The new routing opened in January 1943.
We found this segment from the Bailey Cove boat ramp down to the water level of that day to be in remarkable condition. Some stretches were nearly intact, while other pieces were partially washed away or still covered in 10 to 12 feet of silt deposits. Eric and I believe that part of the road had been uncovered by grading over the summer to allow boaters to reach the receding waters.

This segment is indicated by the shorter yellow line in the Google Sat image at the beginning of this post.
Southern Pacific Railroad Tunnel 6
After concluding our exploration of the Bailey Cove area, we drove up Interstate 5 to Antlers to check out one of the old railroad tunnels exposed by the receding waters. Tunnel 6 is located just north of what was the confluence of the Sacramento River and Charlie Creek. Today, the tunnel can be reached by driving south on Lakeshore Drive south of Antlers about 1 mile. After passing the US Forest Service Lakeshore Station, make a hard left just before crossing the Charlie Creek Bridge. A high clearance vehicle is recommended to travel down the river canyon slope to reach the tunnel.
When built by Southern Pacific predecessor Central Pacific in 1884, it was a just basically a hole dug through rock until sometime in the 1920s when concrete headwalls were added. The south end of the tunnel is lined for about 50 feet, whereas the north portal is not. Since being first inundated in 1948, the tunnel has partly filled with silt, raising the floor probably about 10 feet or more. The tunnel is situated in highly metamorphosed shale and slate, more than likely from some old island arc slammed up against the North American plate many millions of years ago. Also impressive is the the trestle high above the canyon that replaced the tunnel necessitated by the flooding the Sacramento River by the Shasta Dam.

The Sacramento River arm is to the right.The south entrance was lined for about 75 feet somewhere around the late 1920s, along with the addition of concrete headwalls at the entrances. The rest of the tunnel is exposed rock.The river-facing side of the tunnel. The shelf-like area I’m standing on alongside the tunnel was graded to allow for construction of the overhead trestle.The north entrance. The amount of silt that has been deposited for the decades is evident, as the current clearance at this end is only abut 12 feet.This is just as you enter the north portal. As you can see, the tunnel was not lined at this end.Just north of the tunnel are apparently the buried remains of 3 railroad cars that spilled into the Sacramento River in 1903. This is a wheel set visible from one of the overturned cars.The historic 1925 Charlie Creek Bridge just south of the tunnel, and on the west side of the Sacramento River. The current bridge deck was added about 1940 in anticipation of rising waters from filling Lake Shasta. Just further upstream is the 1917 Charlie Creek bridge, which carried the Pacific Highway.A few hundred yards south of the Charlie Creek and Sacramento River Confluence is a concrete retaining wall built to protect the railroad bed. Some of the great geology through which Tunnel 6 was built.
One of the usually submerged historic highway bridges in Shasta Lake
The Salt Creek Bridge was built on the Pacific Highway in 1925 between what is now Lakehead and Redding. This bridge apparently replaced one built some years earlier, as the older abutments are visible underneath the newer structure. It was later abandoned in 1941, as US Route 99 (the former Pacific Highway) was rerouted in anticipation of Shasta Lake inundating the older route (as happened in 1948).
In dryer or drought years, the Salt Creek Bridge is one of the first submerged artifacts to make its appearance as the lake level falls. It is easily accessible from the Salt Creek exit on Interstate 5. Take Lower Salt Creek Road west for about 3 miles at which point you will come to the bridge underneath the towering Union Pacific railroad trestle.
My visit to the site got a little more interesting, as I ran into a gentleman making casts of footprints in the muddy bank of creek upstream of the bridge. He believed them to be evidence of Bigfoot-like creatures. I have to say the footprint and casting of others he had made in the area didn’t look quite human. He proceeded to show me dozens of pictures of like footprints he had found at numerous sites, as well as other weird things that apparently Bigfoot hunters believe are evidence of the mythical creature actually existing. I came away from the conversation thinking I might have to make my forays into the area forests with a new viewpoint.

The previous bridge would have probably been only 15 feet wide. The underside looking towards the east end. The previous bridge footing can be seen in the center.Since the 1925 bridge was higher than its predecessor, the road approachmentds had to raised. This is the reinforcement of the east approach.Evidence of Bigfoot?
All in all, the bridge is in great condition. This is likely due to being submerged in the cold waters of Shasta Lake most of the year. If you decide to drive across the span, beware of the approaches, as there are gaps between the bridge and the road.

Driving home from the Bay Area up Interstate 505 (the “Winters Cut-off), I jumped off the highway at the Midway Road exit just north of the Nut Tree Airport to look for remnants of the Southern Pacific Clear Lake/ Winters Branch along the modern interstate.
I vaguely remember seeing rail cars along the interstate’s predecessor 2 lane highway as our family travelled back and forth between the Bay Area and Siskiyou County in the late 60’s and early 70’s. I rediscovered the railroad branch while looking at old topographic maps of the area recently.

The above topo map shows the railroad running between Hartley Road and the under construction Interstate 505. I explored the stretch between the two arrows, heading north from Midway Road to Allendale Road.

Also at this corner is found a USGS benchmark with its associated witness post, monumented in 1904 (Solano County B 44, PID JS1521).
Along this stretch of the abandoned railbed, a number of small drainages are crossed. Below is one the the concrete culverts used to cross these.

My quick exploration ends at Allendale Road. The next stretch of railbed is now private property across the road.
The railbed heads north towards Winters through the center of the photo.
After a few weeks of self isolation, and the onset of great spring weather, my wife and I headed out for a day trip through eastern Siskiyou County, as well as parts of Shasta, Lassen, and Modoc counties, California, and Klamath County, Oregon.
This is sparsely inhabited country, consisting of national forest lands, large ranching and farming operations, small towns, and stunning volcanic, forested, and high desert vistas. This was mostly a scouting trip to plan future explorations. Some parts of this country I had never been to, and others it had been decades since I visited.
We drove this loop counterclockwise, starting in Mount Shasta.
Inside the 300 mile round loop is found Mount Shasta; the Medicine Lake Highlands, including the massive Medicine Lake Volcano; the McCloud, Pit, and Fall rivers, which flow into the Sacramento and then the Pacific Ocean through the Golden Gate some 300+ miles south; Lava Beds National Monument; the Tule Lake and Lower Klamath National Wildlife Refuges; the remains of historic lumber, agricultural, and railroad operations; large cattle ranches; numerous alfalfa, hay, potato, garlic, onion, and horseradish farms; and Native American reservations and historic sites. The trip also skirts the Klamath River along the Oregon border.
This region on the eastern side of the Cascades is classic Basin and Range landscape, combined with the spectacular results of Cascade volcanism.
We loaded on provisions for the day to minimize our contact with others. We drove counterclockwise from Mount Shasta on this loop. State Route 89 (Volcanic Legacy Scenic Byway) going east takes you through the former lumber town of McCloud, then through federal and privately held forest lands for about an hour until reaching the junction of 89 and State Route 299 (Lassen State Highway). This portion of the drive treats one to an impressive view of Mount Shasta’s east side, as well as titillating turnoffs to a multitude of destinations (McCloud River and its falls; Pondosa ghost town; stretches of the abandoned McCloud Lumber Railroad (now a multi use trail); and Burney Falls and the nearby railroad bridge used in “Stand By Me”).
As you approach the 89/299 junction, the forest gives way to views of grass covered valleys, flood basalts, and other volcanic structures, such as cinder cones and impressive secondary volcanic peaks in this eastern side of the Cascades, such as Burney Mountain (7864 feet). As you head east on 299 to the town of Fall River Mills, the highway climbs a volcanic ridge, with a spectacular canyon carved by the Pit River to the south. Here, one gets a view of Lassen Peak, as well as other prominent secondary volcanic peaks between Lassen and Mount Shasta.
Forests give way to grass covered valleys as you near Burney, driving from McCloud.
It’s amazing how much water there is in these parts. Just north of Fall River Mills lays Ahjumawi Lava Springs State Park, which is only accessible by boat. According to Wikipedia, “The park sits on “one of the nation’s largest systems of underwater springs.” They produce some 1.2 billion US gallons (4.5×109 l) of fresh water per day into the aboveground waterways. Water in the springs originate as snowmelt from the Medicine Lake Volcano highlands.”
A readout just outside of Fall River Mills reveals the volcanic structure of the area. Layered cinder cone deposits are covered by a newer lava flow.
The towns along this trip are for the most part shells of their former selves. With the mechanization of logging and farming operations, the closing of smaller milling operations, railroad mergers, and the shift towards more sustainable industries (i.e. tourism), these are settlements still looking for a purpose and relevance in today’s world. Fall River Mills has done better than most, with a golf resort, nearby hot springs, and retirement development. Other towns are struggling to repurpose themselves.
We stopped to inspect a forest service campground and have lunch. Just a few miles north of Adin is the Lower Rush Creek forest service campground, only 3/4 of a mile off of combined State Route 299/139. It was a nice little campground with the creek running through it, but you drive past several manufactured home hovels to get to it. In fact, the campground is situated within 200 yards of one of these shacks. I’m not quite sure what a night would be like at this site, as it seems that several of the nearby properties house cannabis grow operations. There is another campground (Upper Rush Creek) farther up the road, but the road was not yet open for the season beyond this campground.
At Canby, we turned north on 139 towards Oregon, we finally popped into the southern end of the Klamath Lake Basin. We made our way into the Lava Beds at Petroglyph Point, containing one of the largest panels of Native American rock art in the United States. It was pretty awesome, but sad at the same time, as one also sees the the results of vandalism thrust upon such a significant cultural treasure.
From here, Mount Shasta again dominates the landscape, with Mount McLoughlin in Oregon also visible to the north. By this time, it was getting late in the afternoon. We headed briefly to Merrill, Oregon, where we used the bathrooms at the local Dollar General, then headed west on California State Route 161. We stopped for a few moments to enjoy the golden hour at Lower Klamath Wildlife Refuge, watching the birds at a gorgeous viewing platform. With hunger pains not too far from manifesting themselves, we headed home to Mount Shasta to grab some takeout before finally arriving home.

I spent an hour or so this afternoon exploring a small section of Edgewood Road going north out of Weed. This used to be US Route 99, before Interstate 5 was built and replaced Highway 99. I concentrated my efforts on one curved section of the road, examining old wooden guard rails, and looking for “C-blocks”, which are old California Division of Highways survey monuments. I did not find any, but I’ll return and spend a little more time in the brush looking for any that might exist.

An accessible, historic, and photogenic bridge worth exploring
Trip dates: November 24 & 25, 2017
The Harlan D Miller Memorial Bridge, known also as the Dog Creek Bridge, is an abandoned concrete arch bridge completed in 1927 as part of US Route 99 just north of Lakehead, Shasta County, California. After Route 99 was replaced by Interstate 5, it carried traffic as part of Interstate 5 until a bridge to the northwest was expanded to accommodate both directions of traffic in 1974. It was abandoned and slated for demolition, until saved due to efforts of concerned citizens, and is now managed by the US Forest Service.
Harlan D Miller (1880-1926) was the State Bridge Engineer for the California Highway Department from 1923 until his untimely death in 1926. During his short tenure as State Bridge Engineer he made radical changes to the way California designed bridges. These changes included requiring all highway bridges in the state be designed by the state and designing bridges that matched the geometry of the roadway. The latter often complicated design fork but the final result (skewed or curved bridges) justified the efforts in drivability.
Miller’s most visible effect on California bridges was the consideration given to design aesthetics. His designs were recognized in their own periods as possessing beauty and boldness. Many fine details can be seen on Miller designed bridges including rail and end post details, as well as clean lines and details of the superstructure design.
When my family relocated to the Bar Area in 1963, I remember driving across this bridge as we traveled to the Mount Shasta region to visit relatives several times per year. After the bridge was decommissioned, it had always been my desire to explore the now abandoned structure. I finally had a chance to do so this past week.

DIRECTIONS & ACCESS
Off Interstate 5, take the Vollmers/Delta exit. Proceed west about a quarter mile and turning left onto Fenders Ferry Road. Drive down along the Dog Creek watershed for about a mile, crossing the creek twice and underneath the I5 span until reaching the historic bridge. Park just before the railroad tracks, and climb up the east side of northern end of the bridge.
According to a couple of other websites, there is supposedly access at the northern end of the bridge from the top, at end of a private road where a Forest Service begins. I checked it out and I’m not comfortable at this time on recommending its use. The adjoining property owners have posted a lot of onerous signage, and have tried to unsuccessfully block the easement. I would be nervous parking my vehicle here. Check this post for updates, as I will attempt to get clarification from the Forest Service regarding use of this easement.
