Ogallala Formation, northwest Ellis County, Kansas by Ron Schott

The Tertiary Ogallala Formation is best known as the host rock for one of the largest freshwater aquifers on Earth. In Ellis County, Kansas the Ogallala is exposed at the surface and forms resistant hill-capping exposures such as the ones seen in this Gigapan.

My largest Gigapan yet at 2.45 gigapixels, this monster is stitched from 726 individual photos and took over 40 minutes to shoot.

If the Gigapan robot were able to interrupt the shooting sequence and allow me to move the camera arbitrartily to capture transient phenomena (and then resume the panorama where I interrupted it) I'd have been able to capture a pair of wild turkeys in flight and a herd of cattle that wandered into the field. Not that there's a lack of things to see in this one, but being able to capture transient phenomena such as these would make this image significantly more interesting and educational.
