Coring Lower Pahranagat Lake, Nevada
LOWER PAHRANAGAT LAKE, NEVADA, U.S.A.
Sediments in cores from Lower Pahranagat Lake, southern Nevada, contain proxy data to reconstruct a hydrologic, vegetation, and climate history for
the past 6,000 years. Pollen, plant remains, and mollusks within the core are used to interpret past environments. Radiocarbon dated plant remains and
whole sediment provide a chronologic framework. Close interval pollen samples from rapidly deposited sediments presents a series of snapshots of the
local and regional environment approximately every 13 years. The record reveals decade-long climatic cycles superimposed upon much broader cycles
lasting several hundred years.
