PUNTA ARENAS, Chile, Nov. 3 (UPI) -- A giant iceberg forming in West Antarctica is being monitored and is expected to break off from its parent glacier in the next few months, NASA researchers say.
A crack 20 miles long and 20 feet deep has formed in the shelf of floating ice at the foot of the Pine Island Glacier, one of the largest and fastest-moving tongues of ice on the Antarctic continent, the BBC reported Thursday.
