AccessCounty road 7650
leads close to the Fossil Forest, leaving highway 371 45.5 miles south of Farmington
and heading east. This part of New Mexico is close to the edge of the Navajo Reservation, which breaks up into a series of one mile squares separated by state or BLM land; the road crosses one such square but the badlands lie just outside the reservation. Like most roads with an official number, CR 7650 has a smooth surface and is well maintained, if little used, crossing a wide grassy valley within sight of a few houses. A low mesa rises to the north after several miles, and the edge of the badlands is visible beyond, one mile away. The suggested parking spot is reached after 4.6 miles, at a slight bend in the road, beside a cattle grid and fence running northwards.

From the parking area, a faint wash winds northwards across grassy flats towards the edge of the badlands. These extend over both sides of a narrow ridge running east-west, formed mostly of yellow, brown and blackish mounds, which have a scattering of hoodoos and petrified wood, along the base and a little way up. To the west, the ridge merges with the higher, grass-topped mesa; some larger hoodoos are found around the junction, formed of a thicker, more resistant layer of yellow brown sandstone. On the north side, the badlands continue further west along the edge of the mesa, for another mile. Beyond, to the north, the hills slope down to barren flats (frequented by cattle), which lead to a branched, muddy wash in the distance, while further away towards the horizon is another area of undulating hills, less colorful and with lower relief, but also part of the Fossil Forest.
Most of the petrified wood is fragmented into pale colored, thin-layered pieces, often in a long strip showing where a fossilized log has gradually decayed, but bigger, intact pieces are still quite plentiful, and the best region seems to be towards the southeast, a little way above the valley floor. The rocks hereabouts are just white, brown or yellowish, but the north side of the ridge is more colorful, with a continuous red band and black coal layers at different elevations. All the badlands are quite easy to explore, and the only obstructions are a few steep sided ravines plus occasional sinkholes.
