Where: Yakima County, Washington (46.7° N, 121.1° W)

• Paleocoordinates: 51.2° N, 106.8° W (Wright 2013)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Monroecreekian (26.3 - 24.8 Ma)

• from unit B of the upper Wildcat Creek beds, which is bracketed by dates of 27.16 +/- 0.19 and 26.97 +/- 0.30 Ma (i.e., Geringian or Monroecreekian), and said to be "medial early Arikareean" or "Ar 2" (i.e., Monroecreekian)

• group of beds-level stratigraphic resolution

Environment/lithology: "floodplain"; paleosol/pedogenic tuff

• "distal volcaniclastic facies deposition" involving "air-fall deposits characterized by massive beds of extremely fine to fine ash"
• "Unit B is characterized by massive 0.5 to 10 m thick fine ash tuffs intercalated with 10 to 50 cm lapillistone beds" that "contain well sorted, subangular to rounded, very coarse to fine lapilli-sized mudclasts and pumice, and glass shards, finer plagioclase and amphibole crystals" with "weakly developed paleosols"

Size class: macrofossils

Reposited in the UCMP
