Keywords: Badlands | Alberta
Seventy million years ago, at the end of the Cretaceous, this part of Alberta would have been forest and swamp. Many of the plant fossils in this area from that time are relatives of plants found in modern day China and South America. A walk through UBC's Asian Garden with its dawn-redwoods, ginkgos and magnolias (or the future Araucaria Grove) can well be imagined as experiencing an environment not unlike the one roamed by the dinosaurs of the late Cretaceous.
Horseshoe Canyon is partially protected by The Nature Conservancy of Canada. The Nodwell family, particularly the late Leila Nodwell (interview and article), have contributed greatly to preserving the site.
I'm going to start a new addition to Botany Photo of the Day today - a link to an extra resource that I've found helpful to learn about botany, or photography, or some other topic. I figure if it's been useful to me, it might also be useful to you. I'm also going to bookmark and tag each link on this del.icio.us page.
Photography resource link: The Luminous Landscape - I particularly found the “Understanding Series” and “Essays” of value.

Yes, those are human-made trails. The tannish-grey layer at the bottom of the hill in the lower left of the image is approximately 3m high, suggesting that the total depth of the badlands from the ground surface is roughly 30m +/- 5m.
On a different tack, I wanted to mention that keen observers might note the curvature of the horizon - this is an artifact of a lower-quality lens.

Wonderful. Daniel, have you tried some of the newer tools for stitching together panoramas?

Nice picture!

Jeremy, thanks. I've not tried any stitching for landscape shots, primarily because I often shoot with a polarizing filter. As the camera rotates on the tripod for the panorama, the angle of the light passing through the polarizer changes, and I'm fairly certain I'd get different colours of blue skies. Then again, I probably could experiment with rotating the polarizer, but that might be a fairly lengthy trial and error process.

Great picture Daniel (per usual). Can you give us some idea of scale? Are those human-made trails on the canyon floor?
