I’m in undergrad and I feel like I missed something along the way where yall all know how to do field drawings and what symbols to use for different rocks or what is actually important to draw in the rock record or different sediments from a core. Can someone please share some examples maybe or like a master key for symbols of stuff please? Literally any and all tips are appreciated. I was never aspiring to be an artist but if the shoe must fit lol. Attached are two of my field sketches from a trench we dug, constructive criticism is welcome!
