Abstract Geomorphologic and sedimentologic
investigations in
Park Valley, Tararua Range, have identified the presence of a lateral
moraine toward the head of the valley. This section of Park Valley is
U-shaped, southwest facing with the elongate ridge situated on the true
right (northwestern) side of the valley. A variety of approaches is
used to test the possible process origins of the ridge, including
topographic and spatial positioning, sedimentology, and paleoclimatic
extrapolations. Results indicate the ridge consists of glacial diamict
deposited as a lateral moraine, supporting recent hypotheses about late
Pleistocene glaciation and erosional development of valleys and cirques
of this sector of the range.
