  4.19.24 When I visited Avila Beach this weekend for photos, I noticed erosion in the Avila beach rocks. These rocks are very large and cliff-like. There is lots of rock and and sediment at the bottom of the large rocks, a result or erosion from the waves constantly hitting the big rocks. A few parts of the rocks at the bottom have been smoothed out, also a result of waves crashing on top of them and constantly getting hit with sand, pebbles, etc that are smoothing them out. This has probably been going on for a long time, waves are always crashing o these rocks especially when there is a high tide.

   This was a rather large rock I found in the Yakitutu Neighborhood, where I noticed its been worn down a little by weathering. Its front side has cracks and different fractures and there is some color changes (more rusty orange on the sides and gray on the front.) I think the cracks and fractures are results from physical weathering; this maybe could be from the temperature changes. The color change is a result of chemical weathering and the rustiness is created from oxidation. speed of oxidation depends on how much iron is in the rock as well as how much moisture and oxygen is around, and so I believe it probably has been at least several years before the color change has occurred because it doesn't rain super frequently. same with the cracks, the temperature changes are not so drastic so I think it has been a long time of weathering.

  Photo Blog #1 My Rock! 2.  Wednesday,  April 9th 9:30 PM 3. I found my rock outside my dorm building in the yakitutu neighborhood after coming back from the Cal Poly rodeo. There wasn't many rocks in the surrounding area, especially not ones as large as my palm like the one I found. There were some small pebbles around but not many rocks, and this one stood out due to its size and interesting colors. I don't think the rock was formed in the area I found it because of its drastic size difference and there wasn't another rock that was very similar to it. I think the white, gray, and blue tints to the rock were really cool, again standing out from the rest if the little pebbles that didn't have many colors.
