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.
