Geography field trip By Sally holzoder


On our trip we went to Cape Schanck,Gunnamatta and St Andrews beach.

Figure 1

First stop Cape Schanck

There where many coastal landforms at cape shank including volcanic cliffs and a small depositional pebble beach.

Figure 1.1

Pebble beach

Here you can see an example of a sea stack surrounded in rock pools and small stumps. Most likely created by the arch that collapsed to make the sea stack.

Extra coastal landforms

Exposed vegetation

On our excursion we found examples of exposed and non exposed vagatation. An example of exposed vegetation is show in figure..... Is when vegetation is not protected and hit by the wind coming off the sea.

Figure 1.4

Non exposed vegetation

An example of non exposed vegetation is show in figure ..... Where vegetation is not directly on the coast. Here more vegetation grows and flourishes.

Figure 1.5

Human impacts

Some of the vegetation is trampled on either by people or by animals. So pathways and chicken wire has been installed to prevent this.

Gunnamatta beach

The next stop on our trip was Gunnamatta Beach. This beach was very popular and had many surfers and tourists there. The reason for this is because it is very accessible for people also there are good waves and not many rocks around the shore

Figure 2

Some impacts to the environment

Some impacts on the beach. Because Gunnamata is very popular there are many people which impacts on the beach in a negative way such as stepping on the sand dunes and wrecking the vegetation. Also a carpark placed on the tertiary dune. Where important vegetation like Gumtrees, Hakea Bushes and Ti-Tree are all found.

People who have walked on sand dunes figure 2.1


Also at Gunnamatta another coastal process that adds to its popularity is the rips. Rips form when waves break near the shoreline, piling up water between the breaking waves and the beach. One of the ways this water goes back into the sea is to form a rip current, a thin stream of water moving fast away from shore

Figure 2.2

Uses For Rips

Usually rips are very dangerous for swimmers, if you are ever caught in a rip you should always swim along the shore to get out preferably in the direction of the Long shore drift. However rips are very helpful for surfers because they use the current to get back from the shore out back to the waves.

Figure 2.3

St Andrews

St Andrews unlike Gunnamatta is not a very popular destination due to its coastal landforms

Rocks are very frequent along the shore line of St Andrews. This makes it very hard to get out to the water and also swimmers would also have to be careful when you swim out because the rocks continue out further and are an extreme hazard.

Having rocks like this on a tidal beach creates rockpools and these rocks where formed by destructive waves and erosion.

Figure 2.4

Having many rocks along the shore of the beach and also not having close access to the beach ( no carpark on the dunes) having less people there have had a dramatic effect on the dune ecosystem at St Andrews. However a while ago the dunes and vegetation where in horrible shape but it was restored by a dune recovery project now the beach is healthier than ever.

Figure 2.5

Information at each beach

At each beach there is lots of information either about vegetation, animals that are living there or warnings about rips, tides or where to swim.
