Maps of the region and a sign indicating a "frontier" aspect of El Calafate

A wetland attracts birds next to the town of El Calafate, but Lago 
Argentino's shores are elsewhere barren from the harsh climate

The "Upsala Explorer" takes visitors to Estancia Cristina for food, 
history and excursions. Trip starts with rainbow & rain, ends with sun.

A large iceberg hints of approaching Upsala Glacier; blue ice contrasts with blue-green water (latter caused when light is scattered upward by fine particles of "glacial flour").

This "monster" RV carries tourists across a river & up a steep mountain
trail to view fossils and Glacier Upsala.

Approaching Glacier Perito Moreno from Brazo Rico (see map). Water level rises 
here when the terminus of the glacier blocks the canal (last happened in 1988).

Marine fossils and glacier-polished rocks at 500 meters above sea level

Perito Moreno from our boat; note "tunnel" formed by meltwater.

Upsala Glacier, largest on the Argentine side, 
and Lago Guillermo (formed as Upsala retreated)

Perito Moreno from a lookout platform; 
compare colors of sky, ice, and water.
