2016 Fall Mountain Trip Part 20; US Route 160 in Arizona

Following reaching the western terminus of US Route 163 in Kayenta I turned west on US Route 160 towards US 89 and the Grand Canyon.


This blog serves as Part 20 of the 2016 Fall Mountain Trip Series, Part 19 can be found here:

2016 Fall Mountain Trip Part 19; US Route 163 through Monument Valley 

US 160 through Arizona is entirely contained within the Navajo Nation from the New Mexico State line westward to US 89 near Tuba City.  The current designation of US 160 was extended into Arizona in 1970.

The original designations on the current corridor of US 160 in Arizona was AZ 364 from the New Mexico State Line west to Teec Nos Pos and AZ 64 all the way to US 89.  The designation of AZ 64 was extended east of Cameron in 1961 to the New Mexico State Line via the current corridor of US 160 and US 64.  AZ 64 can be seen built all the way east to the Navajo County line on this 1961 Arizona Highway sectional map.

In 1966 the current route of US 160 from the New Mexico State Line to US 89 was changed to US 164.  US 164 from Arizona extended eastward to a terminus at Cortez, Colorado.  Within Arizona the route of US 164 apparently multiplexed US 89 all the way to Flagstaff.   Some of the US 164 field signage can be seen on USends.com.

In 1970 US 160 was rerouted from Crescent Junction, Utah onto it's current route in Arizona.  The change to US 160 can be seen on this 1971 Arizona Highway sectional map.

As shown in the blog cover photo I made a right hand turn from US 163 onto US 160 westbound in Kayenta of Navajo County. West of Tsegi US 160 meets a significant junction with AZ 564 which is an artifact of AZ  64.


AZ 564 provides access to Navajo National Monument and was covered on a previous blog.

Arizona State Route 564 and Navajo National Monument

Near the Coconino County Line US 160 west intersects AZ 98.


In Tuba City US 160 west intersects AZ 264.  AZ 264 is the longest child route of AZ 64 and extends east through the Hopi Nation and Navajo Nation to NM 264.


West of Tuba City US 160 terminates at US 89.  I turned southward on US 89 to reach AZ 64 to access Grand Canyon National Park.

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&#…
