  WEATHERING  These images are of a stone wall that supports a small tunnel under some train tracks near the Stenner apartments and near the intersection of foothill/California. These pictures were taken  4/10/26 at about 1pm.  1. Given that this wall is located in a tunnel and is supporting the railroad which has been here for I would say 150+ years I think the weathering was mainly done by the past but is still happening due to some moisture from the drainage water that passes through and rain.  2. I think that the type of weathering done here is both bits chemical and physical. (chemical from water/moisture that can get on the walls and flow, and physical form the potential abrasion and general wear that comes from supporting the railroad for so long.)   3. I just think the weathering has occurred through mainly water flow , wind, and general wear. (you could make a point about freezing and thawing on really cold rain night but I wouldn't know) I kn...

 Entry:1 I found this rock a few days ago just forgot to make my post, I believe the date was 4/3/2026 at around 2pm I would say. I was walking home when it caught my eye. The location of this rock was near a lamp post in the Stenner apartments parking lot.    Some things to note about this rock is its color being red with some lighter hues of orange here and there. I saw other rocks in the area that looked sort of like this one but I don't think it necessary formed where I found it. Perhaps in the area but not at the exact location. The reason for this thinking is that this area is commonly traveled by students so maybe someone picked it up and moved it at random, also there is a small creek/waterway underneath the railroad that students cross and I have seem similar looking rocks around there.  Overall its is a neat rock.
