Geocache Description:


Its Lockdown and impossible to place physical caches. So how do you give the essential workers out there keeping us safe something to look forward to on their way to or from work? Well the only option is an Earth Cache. I salute everybody that is keeping us safe during this time and pray that everybody comes through this with not too many bruises (physical, emotional, financial...).

Everybody knows that the Mosselbay area is one of my favourite destinations. 

De Bakke Beach is a special attraction for Mossel Bay, albeit small and relatively quiet. In fact, it is one of the country’s esteemed Blue Flag beaches. This is a well respected award that takes the educational, environmental and cultural value of the beach into account, ensuring that each Blue Flag beach is one that is not only beautiful and safe, but also environmentally and socially responsible.

De Bakke is an ideal beach for swimming, making it perfect for families with children. However, it is also a great water sports beach. Surfing and canoeing are popular activities here, and the two reefs that flank the beach offer wonderful snorkelling opportunities. These reefs also make for the perfect fishing spot, while the views of the Indian Ocean create an idyllic backdrop. During the second half of each year, visitors will be able to spot whales as they skirt the shoreline and entertain onlookers with their antics.

The beach has rocks and grassy patches to facilitate easier strolls, as well as great spots for picnics and romantic retreats. The campground and caravan park are equipped with an ablution block and promise visitors a rustic, hands on experience of the delight that is South Africa.

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) mineral particles or rock fragments (clasts).

Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface, as seen in the Goldich dissolution series. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions.

Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Fine-grained aquifers, such as sandstones, are better able to filter out pollutants from the surface than are rocks with cracks and crevices, such as limestone or other rocks fractured by seismic activity.

Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to tectonic compression within orogenic belts.

 

At the given location you will find 2 boulders. Guess they were just to big to move when the parking was constructed.

Answer the following questions and send your answers to me via email or message the owner.

1. How far apart are the boulders?

2. Describe the largest boulder (shape, size, texture, type of rock)

3. At the back of the boulder there are some lines of a different type of rock. What do you think it is?

4. There is a big sign close to the boulders. What is prohibited according to the sign?

5. Send a picture of yourself at the beach (optional)
