| Summary: | The town of La Paz is situated between the Bolivian
Highland (Altiplano) and the Central
Mountain Range. These two landscape units were
mostly formed during the Tertiary. But at their
intermediate bordering zone, geomorphological
forms have 'later been reshaped. At the end of
the Pliocene, a peneplain was formed (the Altiplano of today) and got covered by volcanic
ashes. Since the fossilization of mammals (Posnanskytherium) in the late Pliocene, a tektonical
uplift of about 3300 ft. has taken place,
and huge moraines built up covering the whole
city area of today. The enormous La Paz Valley
was eroded above all during the last interglacial
period. During the last ice age, the glaciers reached the present upper city border only
and melted away very rapidly 9800 years ago at
the latest. |
