Palynological data from a 989-ft (301-m) core of Pliocene and early Pleistocenesediments from Bruneau, Idaho

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).
