A few weeks back I took a trip here in Ecuador to a river canyon and had a great opportunity to try out the panoramic feature of my camera. The above is a composite from about 10 different photos, and the original, full size is about 12,000 pixels wide. The image covers about a 270 degree arc. As context, you can see both the sun on the right side and the shadow of a tree near my position on the left.
The river visible below is about 1100 feet lower in altitude than I was. The canyon is about 7000-8000 feet above sea level, and near a village called Isinlivi, several hours south of Quito.
Here's a link to a bigger version that is 720 pixels tall and about 5300 pixels wide. Should fit on most screens without vertical scrolling.
