Iceberg Lake Site Map
Paleoshorelines, bathymetry, and sample locations at Iceberg Lake (A). Shorelines
(open polygons) and deltas (shaded areas) are color coded with informal names, intervals
of occupation (in calendar year A.D.), and shoreline elevations (in meters) in legend.
Yellow dots indicate sites where detailed varve chronologies were collected. Most recent
inlet locations for primary (largest arrow) and secondary (smaller arrows) streams are
shown with black arrows. For each stable lake level, a bedrock spillway formed the outlet
at the southeast corner of the lake. Bathymetric contours (labeled with 15 m contour
interval) indicate depth below highest (‘Bunch’) shoreline; question mark indicates
uncertainty of bottom topography in southern, distal basin. Alaska state map (B) shows
general location of Iceberg Lake (IL), Cordova (C), and Yakutat (Y).
