Rifts and Subduction Zones
Yes, I know the title has nothing to do with the image, but the terms pretty well describe my morning so far. My heart is out there in the fog that drifts above the meadow this morning, but my head is into more continental forms of drifting. I need to compress two hundred million years of tectonics into no more than ten minutes of class time tomorrow. I've at least found some very good graphics links to the topic here, and now will have to try very hard not to get bogged down in following every one of them. This is a massively interesting topic to a natureophilic closet geologist like me. Check it out. What do YOU know about how we learned about sea floor spreading and such? This only came together as acceptable science in the 1960's and is foundational (no pun intended) in our understanding about the physical existance of the world's land masses and their history. Ok. Back to the work at hand. No more butterflies for me today.

Fred, how do you do it? Do you ever share some of your settings on your camera with the ones of us who would absolutely LOVE to take that same picture but have no idea exactly how to make it turn out that professional looking?
Maybe you should give a one-day "Come to Floyd and follow me around in my meadow" seminar for some wanna-be photo buffs. We'd bring a treat for Tsuga. :)

not necessarily for your classes
but absolutely fine sites
on the cosmos

and on earth history

both from the beginnings

Absolutely beautiful photo, Fred. I do a lot of macro photos of butterflies in my butterfly garden. My garden was recently certified as a "Monarch Way Station" by the U. Of Kansas. Have not yet seen any eggs layed by the monarchs but do currently have 2 black swallowtail larvae feeding on parsley in the garden..........once they get to be about 2 inches they will leave the garden to overwinter on a tree in the backyard - I only hope I will be able to locaste the chrysalis' at that time....... What a wonder nature is...........

Gorgeous photo, as most of yours are.

This won't help, but I remember how excited I was when I learned about plate tectonics in college in the early eighties. What a fascinating subject! I went home to discuss it with my father, who was a farmer but a geology major from the early forties, and that's when I found out what a new science it was.
Just think, 20-30 years from now there will be something else widely accepted that we have no concept of now. What a wonderful world!
