Small pinnacles in volcanic rocks just above the town of Midas.
These relatively small pinnacles are located in the canyon of Midas Creek, just north of the town of Midas, Nevada.
The rock formation is probably either the Tlb or Tpm of Wallace (1993), with both units being part of the thick Miocene volcanic section erupted during formation of the northern Nevada rift, or eastern northern Nevada rift (NNRe) of Glen and Ponce (2002).
The pinnacles are two shadowy dots on the ridgeline near the center of this MSRMaps airphoto, west of an in-canyon set of builings and trees.
The [semi] coressponding MSRMaps topographic map indicates that the pinnacles are less than 40 feet high. I would guess that they aren't even 20 feet high, based on my mid-July, driving-through-canyon perspective.
