The Miocene Trapper Creek flora of Idaho has been interpreted as an upland assemblage primarily dominated by montane conifers. This is quite unusual for its young age, between 13.9-8.6 Ma. Trapper Creek also represents a community disturbed by volcanism. Therefore, the types of species present are important for ecological reconstructions. Interpretations of the ecological dynamics of Trapper Creek have been based on both pollen and macrofossils. However, the palynomorphs of Trapper Creek have never before been properly illustrated. Digital photographs were taken of numerous Trapper Creek palynomorphs. This qualitative analysis of the variety of species present is important to establishing the validity of previous research.
