Thanks for your input RAZD. My sister-in-law is a professor of geology with a specialism in glaciology. She'd be able to very clearly show where the errors are in the discussions here but when she's not doing field work or attending conferences, she's teaching at the university, so she's busy. She's also reminded me that I'm not going to change anyone's mind here LOL. I admire her for her dedication to her job and for making headway in a mostly-male profession which includes frequently "roughing it" out in the field. She's only just received the professorship promotion.

She said she'd send me some of her lecture notes. Whether or not they have any bearing on the discussion here, I'm always interested in what she's up to.

And no, she doesn't like teaching students who don't want to learn . . . no teacher does, of course. And she also doesn't tend to get YECs in her classes because being a geologist means looking every day at evidence for an old earth. There's no denying it, ignoring it, or getting around it in any way when it's there in front of you.
