North Wash to Marinus Canyon Professional Review and Guide
"Marinus Canyon is a classic, dry desert gorge, embraced by fluted 600-foot walls of Wingate sandstone. The low elevations of the canyon make it a fine choice for an early spring or late autumn outing, when higher canyons, such as those on Cedar Mesa, are too snowy or cold. There are no trails here; you simply follow the dry wash upcanyon. Although the route is generally easy to follow, the wash is sandy and for much of the way you’ll be rock-hopping and weaving among boulders.
Enter the mouth of Marinus Canyon via the small earthen dam, then simply make your way up the rocky, boulder-strewn wash. A scattering of Fremont cottonwoods, tama-risks, and rabbitbrush fringe the usually dry wash, while the green foliage of single-leaf ash and apache plume, with its white spring blossoms and feathery summer fruits, dot the slopes above.
The wash begins amid the rocks of the Chinle Formation."
