Rock samples were collected from the Darwin Glacier region (6 samples) during the 06-07 season. Over 100 samples were collected from the Lake Wellman, Hatherton Glacier area during the 07-08 season. The samples were collected for cosmogenic dating. The data tables contain technical data required for cosmogenic dating analysis. Geomorphological mapping was completed in the Lake Wellman area in the 07-08 season. Individual rock samples were logged and recorded with information on each sample including date collected, geographic locality, grid reference (lat/long), altitude (m.asl), rock type/lithology, glacial stage/age, site description, surface character, depth/thickness, boulder dimensions, topographic shading, surface slope, picture number and comments.
