Description
The Northern Patagonian Ice Field is a vestige of the
San Quintin and San Rafael — nearly reach sea level to the west at the Pacific Ocean. Smaller exit glaciers, like San Valentín and Nef
, feed numerous rivers and glacially carved lakes to the east.
Sir Crispin Agnew of Lochnaw, spent 5 months carrying out scientific research on and around the ice cap, including on the Benito Glacier, and three members of the expedition carried out a north-to-south crossing from the foot of Monte San Valentín down to the snout of the Steffen Glacier.[1] Martin Session, the glaciologist on the 1972/3 expedition returned to the Benito Glacier with others in 2007 and 2011 to continue his research.[2]
The Northern Patagonian Ice Field lies in
Liquiñe-Ofqui Fault Zone, to the north the Exploradores Fault Zone and to the east the Cachet Fault. To the south there is possibly a zone of extensional faults around Tortel Fjord.[3]
