Location of Petrified Forest, Route 66
Petrified Forest has a dry semi-arid climate with hot summers and cold winters. The day-to-night temperature swing is considerable throughout the year due to the low relative humidity; this means that Summer nights are pleasant and cool, but winter nights are quite cold.

Route 66 to the Petrified Forest map
You can reach Petrified Forest along Interstate 40 and Old Route 66 in Arizona.
Route 66 in the Petrified Forest National Park
For those who'd rather drive along the freeway, go along I-40 from Sanders to exit 311, and enter the National Park (you will have to pay a fee to do so).
Once in the park you can visit the remains of two classic Route 66 Trading posts on the old (unpaved alignment of Route 66). Below we describe this short tour.
Painted Desert Trading Post
There were actually two Trading Posts with a very similar name on Route 66 east of Holbrook in the Petrified Forest area: the Painted Desert Point Trading Post (closer to Holbrook) and the Painted Desert Trading Post (further east), we will start with the latter.
Painted Desert Trading Post
It is further east (see this map with directions), head north from Exit 311 enter the park, pay the fee and check at the Visitor Center for additional information.
Just ahead, take a left along the dirt road eastwards, drive east for 6.3 miles along Pinta Rd. Cross the bridge over Dead Wash (named so because a prospector named Lewis was found dead there by his neighbor, Jackson, in 1897). Just ahead is the Post.
The Painted Desert Trading post offered rugs, curios, jewelry, and also sandwiches and cold beverages. It had two gas pumps in the front (no canopy), and a simple white building with a flat top and the three windows that faced forward with a single entry door.
It was built by Dotch Windsor in 1942, who ran it with his first wife Joy Nevin until they divorced in 1956. It was the dawn of the Interstate period and Dotch closed the post.
Nowadays, eighty years later, the passing of time has caused, ruin and decay. As you can see below, the dorway is empty and the windows gone. The words Desert Trading Post can still be made out on the front of the former store:
A Short tour in the National Park
The views on this side of the park are amazing, the Painted Desert deserves its name.
Head back to your starting point on the paved road. Here is a short gap in US 66 (The original Route 66 continues west but cannot be driven here) you can continue your drive in the park, visiting Tiponi Point, Painted Desert Rim and visit the historic Painted Desert Inn and Kachina Point. All of them are located on Petrified Forest Road, which describes a wide arch to the north, and then heads west and south again.
Stop at the scenic points of Pintado Point and Lacey Point. Then you will reach the Route 66 Monument.
Route 66 Marker
See where it is, in this map, the point marks where Route 66, coming from the trading post in the east, crosses Petrified Forest Rd. and heads west into the desert. The roadbed is not visible at ground level, but can be seen in satellite images. A line of telephone poles marks the alignment of the original Route 66 (you can see them in the photograph).
The marker has a concrete bench with a Route 66 shield, and a chrome vintage car bumper set in it. It belonged to a 1957 Cadillac Fleetwood. It is a front Dagmar Bumper (the word Dagmar came from the splendid figure -and bosom- of Virginia Ruth Egnor's 1950s TV character "Dagmar").
Next to it are the remains of a rusty 1932 Studebaker and a sign with information titled "Highway of Dreams".
At this point you have the choice of visiting the rest of Petrified Forest Nat. Park, which stretches north to south between I-40 and US. Hwy 180.
Or you can also retrace your steps to I-40 and continue west exploring the alignment of Route 66. We suggest doing both! The park is amazing.
Route 66 heading West from the Park
Return to Exit 311 on I-40 and head west along the freeway. The original US 66 alignment coming from the Route 66 Marker is now buried under the bushes, it crosses the freeway 2 miles west of Exit 311 (see map).
The freeway cuts the old alignment at this point; the original Route 66 continues on the south side of I-40. This alignment can be driven. To reach it if you want to drive along it, leave I-40 at Exit 303.
This is map of the driveable US 66 alignment from Petrified Forest to Little Lithodendron Wash, it is a 8.1 mile-long segment.
At the exit, turn left, eastbound to the "other" Painted DesertTrading post. It is a 3.8 mile drive.
Painted Desert Point Trading Post
1940s postcard of the
Painted Desert Point Trading Post
It was located 21 miles east of Holbrook. You can reach it (map with directions) from Exit 303 on I-40 head to the south side and drive east for 3.8 mi. It is on the north side of the Old Route 66.
Built in 1946, it sold Shell gasoline. Only the foundations of the rectangular building and the concrete base of the gas pumps remain. At one time it was rumored that it had illegal slot machines. It was run by Harry Charles Osborne, who in 1952, aged 78 was forced to kill his deranged son at the trading post.
Head back to Exit 310, and head one-half mile east along US 66 right to head west along old US 66 to reach the bridge:
Little Lithodendron Wash Bridge
Route 66Holbrook, AZ.
Listed in the National Register of Historic Places
A wooden truss bridge built in the 1932 on US Highway 66
This wooden bridge is 243 ft. long and 23 ft. wide, its longest span is 18.7 ft. long. It crosses the Little Lithodendron Wash, also known as Carrizo or Little Carrizo Wash -Carrizo is Spanish for "rush".
The word Lithodendron combines the Greek words "Lithos" (stone) and "Dendros" (tree), "stone tree" after the neighboring Petrified Forest National Park.
The wash has several branches that Route 66 had to cross. Two bridges were erected in this spot, and only one survives. It is a timber tressle bridge built 1932 and rehabilitated in 1986 it can still be driven across.
It is a "tressle" bridge because the short timber spans are supported by a rigid frame or "tressle". This is a Street View of the historic bridge.
Continue west along Route 66 for 2.5 miles till you reach Exit 300. Here I-40 curves so the old alignment of Route 66 lies on the north side of the freeway, and you can see the old road from I-40.
From this point west, the 1930s alingment lies under the freeway all the way to Holbrook, where at Exit 289 it resurfaces and you can drive along it into the town.
The 1930s alignment is beneath the freeway, but the first US 66 aligment survives as Pima St. and Horse Head Crossing. This Map shows its course. Since it starts and ends at dead-ends, you must access this segment from Exit 294.
While at the exit, visit another Route 66 Classic, from the 1960s, a former Stuckey's.
Sun Valley Stuckey's
7699 Sun Valley Rd, At exit 294
On the southwestern side of the exit is the former Sun Valley Station. Located only 8 miles east of Holbrook, it once had a Texaco gas station and a Stuckey's convenience store chain. Its slogan was "Relax, refresh, refuel!".
The building was "8 miles east of Holbrook, Ariz. Hwy 66 & Interstate 40", and it is still standing, with its typical "A" shaped roof. Now it is a knifeshop.

The Petrified Trees
200 million years ago, during the Late Triassic Epoch this area was a lush rainforest with ferns and coniferous treees 10 ft. in diameter and 180 ft. tall. As they died or fell they were buried by sediments or covered with volcanic ash (known as the Chinle Formaiton) that preserved them before they decomposed. Ground water later dissolved silica in the volcanic ash and saturated the logs and crystallized, replacing what was once living tissue with quartz. This preserves the life-like appearance of the wood.
Iron oxides give the petrified wood its red, organge and ochre hues.
60 million years ago, the uplift of the Colorado Plateau led to the erosion of the younger rock that overlay the Chinle Formation, and this uncovered the logs and fossil plants.
The park is one of the few in the world to have flora from the LateTriassic: cycads, ferns, ginkgoes, lycopods and more.

Painted Desert Inn
Petrified Forest N. P.Holbrook, AZ.
Listed in the National Register of Historic Places
A classic National Park lodge built in 1920 and restored to its original 1949 appearance. Now a museum.
Built in 1920 by Herbert David Lore as a lodge, it was acquired by the National Park Service in 1935. It was originaly built in petrified wood, but it was soon renovated in a Pueblo Revival Style after it was purchased.

It was renovated by Mary Jane Colter in 1947 and closed in 1963 when a new visitor center replaced it. It was saved from demolition in 1976 and was designated a National Historic Landmark in 1987.
