Grand Canyon-Parashant National Monument. It is approximately 60 miles southwest of Fredonia, Arizona and about 60 miles south of St. George, Utah. It is about 7 miles north of the Mount Logan Wilderness
.

The namesake of the wilderness, Mt. Trumbull, is 8,028 feet (2,446m) at its highest point. A 2.5 mile trail to the top can be accessed from

Flora

At lower elevations the vegetation of the wilderness consists of

ponderosa pines
. The area was heavily logged in the late 19th century resulting in most ponderosas being new growth, thus small, but some towering old growth ponderosa pines can be seen in the Wilderness that are more than 500 years old. There are also various types of grasses which grow intermittently throughout the wilderness.

Fauna

The wilderness is home to a variety of animals.

lizards in the area including horned lizards. Birds present include red crossbills, Steller's jays, common ravens
and many others.

Geology

The Mt. Trumbull mesa is capped by a 3.6 million year old dark grey basalt lava flow, one of the first eruptions in the Uinkaret volcanic field. The volcanic field has spawned at least 213 known eruptions since then, including seventeen lava flows that poured into the Grand Canyon and dammed the Colorado River.[2] The most recent eruption was at Little Springs approximately 960 years ago.[3] Its lava flow can be seen just south of Mt. Trumbull along BLM road 1044. The Mt. Trumbull lava flow cap protects the colorful Moenkopi Formation beneath that would have otherwise been eroded away long ago. An undated and unnamed cinder cone sits on top of the mesa. It erupted through the original 3.6 million year old basalt cap likely in the last few hundred thousand years based on minimal surface erosion. It ejected bright red volcanic cinders and lava bombs which can be seen along the switchback trail.
