Summary:

[Spelled Gleneyrie by Finlay.] Named for Glen Eyrie Creek [west of Manitou, El Paso Co, CO in the Denver basin]. [No type locality designated.] Exposed in a stream bed in Quarry Canyon a mile northeast of Manitou. Has an outcrop width of an eighth of a mi and length of 3 mi. Is a 40 ft, gray to buff, resistant, finely laminated sandstone made up almost entirely of quartz grains. Has thin bands of black shale near base in which LEPIDODENDRON remains have been found. These are the first plant fossil remains of Pennsylvanian or Pottsville age found in the Rocky Mountain region. Overlies probable Millsap equivalent, or probably Mississippian rocks. Unconformably underlies Fountain formation.
