Thank you so much for your videos! I am a geology student at a university (a VERY old geology student) and your videos really help in understanding topics that might be a little muddy. I have always thought the angle of repose was this magic angle that applied to every situation. Thinking specifically of fluvial crossbedding and you always read the angle of repose is some set number and that's written in stone. I live in a sedimentary area with some Penn fluvial crossbeds and can't make sense of the angle cos it don't seem like the textbooks. These are textbook quality fluvial crossbreeds, but the Penn is very eroded around here and just occurs on the tops of hills, so I an never sure if I'm looking at the Penn sitting on the Miss or just a boulder that might have moved a bit over the (lot) of years. Kinda neat outcrop because it really is just a large bolder and you can walk behind it and see the troughs. Don't think I can post a pic in comments or I would. The crossbreeds are compacted into maybe a couple of meters, so I have a good horizontal reference on top and bottom. Still can't make sense of it :). Thank you so much for your videos. I know you are making them for your students, but they really help a lot of other folks like me who are trying to sort things out.
I am so glad they are helpful! I was going to keep them unlisted and just have my students access them but it seem like a lot of others are using them so I am glad I made them public!
