Summary:
High Park lake beds. Remnants of a series of local sandstones and conglomerates lying either on granite or on a thin rhyolite flow, the conglomerates characterized by pebbles of extremely hard Algonkian quartzite, granite, and gneiss. No fossils; but beds appear to be older than adjacent volcanic breccia, which in many places rests on Florissant lake beds. Is older than Alnwick lake beds. [USGS adopted (ca. 1938) Tertiary (late Miocene or Pliocene) age for this unit.]
Named from High Park, Pikes Peak region, eastern CO.
