Palynological data from a 989-ft (301-m) core of Pliocene and early Pleistocenesediments from Bruneau, IdahoEntry ID: USGS-OFR-92-713
Abstract: This data set is part of the Pliocene Research, Interpretation, and Synoptic
Mapping (PRISM) Program. Information about the data set are available on line

The following information about the data set was provided by the data center
The U.S. Geological Survey's PRISM (Pliocene Research Investigations Synoptic
Mapping) ... Project is conducting multi-disciplinary research of paleoclimatic
conditions during the middle Pliocene, the last period sustained warmth in
Earth history. Mapped paleoclimatic data from the period will be used to
validate numerical-model simulations of past climates, and will thus aid in the
improvement of these models' ability to predict climates substantially
different from that of today. Additionally, these data may provide insights
into the nature of regional climatic patterns in a warmer-than-modern global
climate and help determine the nature, amplitude, and timing of paleoclimatic
variations within this warm period.
In an effort to extend the geographic coverage of the PRISM data set to
increase knowledge of Pliocene paleoclimatic variations in the interior of
North America, a 989-ft (301-m)-long sediment core was obtained from the
Bruneau and Glenns Ferry Formations near the town of Bruneau, Idaho. This
report presents basic coring data and palynological counts from this core, and
some preliminary observation on their possible paleoclimatic significance.
The core site is located at elevation 2925 ft (892 m) in the NE 1/4, 1/4, Sec.
18, T6S R6E, Idaho (42 degrees, 54 minutes, 31.5 seconds no latitude, 115
degrees, 46 minutes 46.8 seconds west longitude).
