Map of Early Eocene Okanagan Highland fossil sites. Red stars represent beetle sites: Republic, Quilchena, and McAbee, with confirmed Pachymerina; Republic and McAbee, including beetles assigned to Caryobruchus + Speciomerus; and Driftwood Canyon with likely Pachymerina. Green dots represent other Okanagan Highlands sites: Allenby Formation with palm macrofossils in chert, Uhlia allenbyensis (15); putative palm pollen reported from the Allenby Formation, Quilchena, Falkland, McAbee, Hat Creek, and Driftwood Canyon (for Quilchena, see Palms as Indicators of Winter Temperatures; for others, see ref. 18 and references therein). No evidence of palms has been reported from Okanagan Highlands localities at Republic or Horsefly River.
