Black Mesa to Teec Nos Pos — Four Corners Plateau Road via Lukachukai Mountains
Navajo high country most overlanders miss entirely.
Black Mesa is a massive coal-bearing tableland in the heart of the Navajo Nation, and the dirt and gravel roads that thread north from its edge toward Teec Nos Pos cross country that feels genuinely removed from the twenty-first century. The route climbs from the scrub flats northeast through the Lukachukai Mountains — a forested island range that most overland drivers blast past on US-191 without ever knowing it exists — before dropping back to the Colorado Plateau floor near the Four Corners monument. The Lukachukais top out around 9,400 feet and carry stands of ponderosa and spruce that look nothing like the desert below. Canyon overlooks, Navajo chapter house settlements, and the occasional free-range sheep herd are your waypoints.
This route crosses Navajo Nation land — a Navajo Nation backcountry permit is required and must be obtained in advance from the Navajo Nation Parks and Recreation Department. Treat that seriously; enforcement happens and the land deserves respect. Road condition varies from graded dirt to rough two-track; stock 4WD with high clearance handles it in dry conditions. Mud season in spring can close the mountain segments entirely. Fuel in Kayenta or Chinle before you leave — services are sparse. No surface water you’d want to drink; carry your own. Best season is May through October. Cell service is essentially nonexistent across most of this route.

Frequently asked questions
Can a stock 4Runner or Wrangler handle this trail, or do I need a built rig?
A stock 4WD high-clearance vehicle like a 4Runner or Wrangler will get through in dry conditions. The Lukachukai mountain sections have rutted climbs and loose surface that will punish low-clearance rigs, so anything under about 8 inches of clearance is a gamble. Lockers help on the steeper pitches but aren't mandatory.
When does the trail open and is it passable after rain?
May through October is the reliable window. The dirt and clay sections through the high country turn into a greasy mess after monsoon rain — which runs hard July through September — and can become impassable even for capable rigs. Check conditions locally before committing; flash flooding in the canyon sections is a real hazard, not a liability disclaimer.
Do I need a permit to drive through Navajo Nation land, and is there a fee?
Yes, a Navajo Nation recreation permit is required. Get it through the Navajo Nation Parks and Recreation Department at navajonationparks.org before you go — don't assume you can sort it out at the trailhead. Fee amounts can change, so confirm current pricing directly with the department.
What's the hardest section of the route and what should I actually expect?
The climb through the Lukachukai Mountains is where the trail earns its moderate rating — steep, rocky two-track with loose surface and limited bailout options if conditions turn. At 9,400 feet the air is thin and the weather can shift fast; afternoon thunderstorms in summer are routine, not rare. Nothing technically extreme, but the remoteness amplifies every mechanical problem.
There's zero cell service for 87 miles — where do I get water and how far is the nearest gas?
Carry all your water. There are water crossings on the route but potable sources are not reliable or confirmed along the way, so treat anything you pull from the trail. Kayenta is your last solid fuel stop before departure — at 87 miles of backcountry driving, budget for poor fuel economy and top off completely before you leave pavement.
