Perito Moreno Glacier
Occasionally, the glacial front does not completely obstruct the natural passage of water with an ice dam, but it approaches close enough to prevent water from passing freely, so without reaching elevation, an arm cut in Rico occurs. These events are classified as minor downloads. This is what happened in October 1996, when the Rico arm rose about a meter. At the end of that month the water pressure opened a greater passage in the walls of the glacial front and the discharge began, but slowly, since the passage had not been sufficiently open, so the maximum peak of the discharge flow occurred at the end of January with a value of 123 m³ / s, the dimensions being equalized on both sides only at the beginning of April.8 The events of 1994, 1995 and 1997 show similar behavior and magnitudes to those of 1996.

Argentina > Santa Cruz Province
The lake occupies a continental-scale graben formed by SWS-ENE normal faults that have resulted in down-dropping the bottom of the lake to 350 meters (1,150 ft) below mean sea level. Preservation of younger lithostratigraphic units within the graben form reverse stratigraphy with older units exposed at higher…
