UNIT DESCRIPTIONS QUATERNARY SYSTEM RECENT/PLEISTOCENE Geology Undifferentiated Variable mixture of strata and deposits that have slid to the base of steep slopes.

As a result these maps can be used to identify areas that are vulnerable to slope failure, but are not an up to date assessment of all landslides for the area.
