Yesterday, we dragged all the kids out of bed by 6:45am and drove about 2 hours north to a place called the Pinnacles Desert. The Pinnacles Desert lies on the "Turqoise Coast". Perth is located on the "Sunset Coast". If you go a little further north you will be on the "Coral Coast". I'm not sure if there's a geographical feature that delineates the different coasts or if it's something else. In any case, it was our first visit to this area, although, we've gotten about half way there on a couple of other trips.
The Pinnacles Desert is located in Nambung National Park. Throughout the park there are these enormous white sand, monolith-like dunes. Because we've had quite a bit of rain lately the area was quite lush and green . So whenever one of these white sand monstrosities popped out of the red and green desert it was surprising. The are formed by the prevailing winds, which can be quite strong in certain areas, so strong that an international wind-surfing competition is held in nearby Lancelin annually.
The Pinnacles are really quite interesting. They are difficult to describe and frankly, the photos don't do them justice. The tallest one's are maybe 20 feet high but most are probably between 4-8 feet in height. The cause of the pinnacles are a question of some debate. They are limestone formations that most people believe are the result of seashells that were broken down into lime rich sands which were blown inland to form high mobile dunes. After that there's some disagreement. Some think that the broken down limestone sand was fused together by the aciddy rain and grew upwards like a cave stolagmite. Others believe the minerals from the sand seeped into trees and essentially fosilized them. Others believe that the minerals went into the tree roots. Then over thousands of years as the ground was eroded by wind and rain the limestone tree roots were exposed.
The area covered by the pinnacles is actually quite vast or at least it seems that way. Today, the Pinnacles receives 250,000 visitors per year. However, the area was really "discovered" until 1960 when it was included in Nambung National Park. Although, I'm confident that it was likely "discovered" by the aboriginals a few years before that.
After our tour through the Pinnacles Desert we continued north to Thetis Lake. It's a small lake tucked away just offshore. It's main feature is that it is 1.5 times more salty than the ocean. This results in some interesting things. The first of which is there are no fish in the lake. The second is that it is a very good place to watch certain bird species. The third, and most unique, is that it is home to Stromatolites (pictured above). Stromatolites are colonies of cyanobacteria. These are microbial communities that produce oxygen. These were once widespread through the planet but are now only found in isolated places where the conditions are suitable with few marine animals to eat them. Further north, in the Pilbara region, there are stromatolite fossils that date back to 3.4 Billion years ago! That would make them one of the oldest living organisms on the planet. These particular ones in Lake Thetis are a mere 3500 years old.
After the visit to the pinnacles and stromatolites we settled down for a picnic lunch. We are getting very good at picnics, although, I've been very good at anything involving the consumption of food for several years now. Despite it being winter in this region, it still is fairly nice during the day. It was t-shirt weather in the afternoon during our picnic and we managed to have a day mostly without rain.
Nothing follows a picnic quite like a walk along the beach.

This weekend marks a couple of important occasions:
1) It's Fathers Day in Canada. So, for all the Canadian fathers I hope you have a great day of sitting around, watching sports, having your meals made for you and occasionally scratching yourself. Or in other words, the same as every other day.
2) It's my mom's birthday. Happy birthday mom! Hope you have a great day!!!
