Info about Gauja valley
Gauja Valley among other natural areas are characterized by the
geological conditions and habitat instability. It is determined by
the steep terrain articulated by the great relative height
differences and the peculiarities of geological structure.
Important is surface activity in terms of the asset side and the
depth of erosion. Accompanied by a continuous movement of the Gauja
bed, bank and flushing slip down, locations also increased gully
formation. Short, but very interesting is Gauja valley part in
Sigulda area. In this part valley had gnaw throw dolomite instep
and in the right side you can see a Turaida support.Sigulda
surrounding valley slopes are narrow and steep, indented with short
side gullies, covered with a thick wood deck, which occur in
various broad-leaved tree species. At the foot of slopes in several
places are sandstone cliffs with caves: Gutman Cave and Devils
Cave, Valley of crows Vejupites Cave and Petera Cave. Sandstone
caves encountered groundwater and rivers, as well as human
activities. Valley in this area is clearly demarcated - behind the
top edge of the slope begins immediately surrounding the raised
corrugated cultivated plains. The riverbed is twisted it consists
of loose sand and gravel deposits large quantity of them are moving
up the stream. Therefore Gauja depth is uneven over time and
rapidly changing. River is a lot of whirpool, especially between
Cesis and Sigulda. Throughout the Gauja valley is very good visible
above the flood three terraces. A few meters above the floodplain
overlooking the first terrace. After the nature of the sediment
close to the floodplains. The second terrace above the flood valley
at the top of slopes is greater than 40 m, the lower end - about 15
m above sea level. Around 4 - 5 m above this one is running the
third terrace above the flood. Both of these terraces consist of
dusty or fine sand from coarse sand and gravel deposits.
