Riley Coleman - PSC 103

 This week, I went for a little nature walk with my roommate, Claire, to find some natural examples of buoyancy. We were lucky enough to stumble upon a small creek, where there were some sticks floating. This was a great opportunity to take a picture for this project. The stick I placed in the water was able to float due to the fact that it is less dense than the water, therefore it is able to stay on the surface. I took these photos today, April 25th, at around 2:30 pm on a trail behind my apartment complex at Cal Poly. 

This Saturday around 2 pm, my roommate, Claire, and I went on a cool little drive down by Avila Beach here in San Luis Obispo. Here, we pulled over along the road to find a cliffside that seems to have a prime example of erosion by water and/or air. As you may be able to tell, this rock formation seems to have a multitude of cracks and crevices in which could have been formed by flowing water or by gusty winds. As you also might be able to tell from these photos, is that there are parts of broken rocks also below the cliff, which indicates that this cliff also could have been broken apart by natural causes. 

This week I was lucky enough to be able to take a trip down to my hometown of San Diego to get my second Covid vaccine! Along the way, I spotted some great examples of erosion along Highway 101. This first photo depicts a highly eroded mountain along the freeway near the city of Camarillo. Some evidence that shows the side of this small mountain has been eroded is the fact that there are deep crevices and caves within the mountain itself. In addition, the rocks seem to have very broken edges which could indicate that they have been broken or chipped at through weathering. The second photo is of the side of a cliff near Ventura. This cliff seems to have been eroded due to the apparent rock and sand slides along the side in addition to what looks like areas where water could have previously flowed. In both photos, it seems the weathering has been occurring for probably hundreds, even thousands, of years. Since their formation, each of these larger examples of erosion have probably been f...

 This week I went out to Pismo Beach for my rock hunt! I found a beautiful blue stone that I thought would be great for this project. I took these pictures on Wednesday, March 31st around 4pm. What really drew me to this rock initially was the color and the location. Both were relatively unique which made it an interesting option for me to pick. I found this little stone sitting in the sand pretty far up the beach and there wasn't many other rocks around it. Below I attached some photos of the location and the rock!
