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...
